The Kitty Paddle and Guinivere's Aureola deals effective damage against tome-wielders.
Jeorge's personal weapon Parthia has an exclusive refinement that mitigates damage from a tome wielder's first attack and gives him +6 Atk during combat if he's facing ranged opponents, including tome wielders.
The exclusive refinement for Regular Felicia's eponymous Plate gives her an extra special charge for each attack she lands when she is in combat with a tome wielder, which synchronizes quite well with her high Res and Res-based special Glacies.
Dragons Breaths which are released post-2.0.0, including refined and character exclusive, are a Downplayed Trope. They target the lower defensive stat of any unit with an attack range of two, including tome users, whose Def is usually lower than their Res.
The Distant/Close Ward skills allow the user to gain +5 Atk/Res and allow the user to counterattack regardless of range if the foe uses a tome, staff or breath weapon, and in the latter's case, negate skills that target the user's lower defensive stats, allowing them to increase their offenses while reducing damage against magic users.
The exclusive refine for Regular Jaffar's Deadly Dagger and Regular Innes's Nidhogg prevents mages from counterattacking them.
Magic Pants: Anna discusses creating and selling special outfits for Laguz characters to use when they transform in-between forms.
The reason why you fight all the Heroes in the story. Heroes defeated by the Emblian Empire must agree to the contract, which states that they must serve the empire, or they'll presumably be killed. However, the contract is null and void if someone else defeats them in combat. A majority of Book I (and a few Paralogues) focuses on freeing the Heroes from the Empire's contracts. From Book II onwards, the plot is less focused on the contracts, although some Heroes (i.e. Regular Micaiah, Sacred Memories Eirika, Exalted Chrom, Kaze) still comment on them.
Heroes that are summoned by the player through the Breidablik are also bound under a contract, which a few characters point out.
Alfonse, Sharena, and Anna all start out at two starsnote four stars since 2.5.0 and require significant investment to become viable, but once they get upgraded to five stars, they all become pretty decent to use.
Com Mons are usually not summonable at the 5-star rarity, unless they are featured in a summoning focus. Other than that, the only way to get them at 5 stars is to spend lots of feathers to upgrade them from lower rarities. Additionally, most of these units gain access to new personal weapons through version updates, which in turn can be refined with unique effects or stat boosts by using the rare Divine Dew material.
Units designated as trainees such as the youthful dragons (like Fae or young Tiki) or villagers and trainees (like Donnel and Amelia) start with low base stats, but when they're raised to their highest levels, they end up having higher base stat totals than other units of their class.
Grand Hero Battle units, who are never acquired as 5-star units; they must first be ranked up from 3 or 4 stars. They also usually have poor area of effect Specials with long charge times and rather underwhelming skillsets. However, it's almost always worth it to upgrade them to five stars and put enough investment into them. They usually have pretty good stats, and some of them can acquire unique weapons with incredible effects. Most notably, Xander and Camus acquire weapons that have Distant Counter built in, and Michalis gets the Hauteclere, which accelerates the charge time of his special and boasts a high 16 Mt.
It's theoretically possible to turn any unit you like into something amazing, even units that are only good for Cannon Fodder or Skill Inheritance. The process tends to be a lot more involved and drawn out than simply pulling a 5-star unit, requiring a large amount of Promotions, Merges, Skill Inheritance and Dragonflowers, and sometimes Trait Fruits, to bring them up to par with the game's all-stars, but it can be done. It's a common practice for players to do this with their favorite character at the very least.
Magitek: In Paralogue 8, Anna uses a magic tome that is basically a modern camera in all but name. In the following Paralogue, Anna uses a magic tome that works like a video recorder.
Marathon Level: Tempest Trials, Squad Assault, and Chain Challenge have you fight on 3 to 10 maps in a row with no breaks or After-Combat Recovery. The Blessed Gardens initially only gained one "new"note every map in the Blessed Gardens thus far is merely an already released Paralogue or Main Story map where its units have souped-up stats map every several days, but the introduction of Blessed Grounds as part of the Gardens began adding two maps, then eventually three.
Meaningful Name: The two warring kingdoms are the Kingdom of Askr and the Empire of Embla. In Norse Mythology, Ask (or Askr) and Embla are the first two humans, basically the Norse version of Adam and Eve. On top of that, Askr means "ash tree," and Embla sounds like "emblem," so the two names combined could be interpreted as "ash emblem" which is very close to "fire emblem".
Halloween Xane. While his has stats to at least make him work if he's alone, if he is near allies, his stats during combat is mostly dependent on his allies near him with his weapon. His weapon Jokers Wild, in addition to being the only weapon that gives +5 HP by default, allows the user to match stats equal to the highest Atk/Spd/Def/Res of all allies within 2 spaces of the user during combat, each calculated individually, and if all allies have certain stats lower than him, his stats decrease during combat as well.
Farina. Her Hotshot Lance allows her to gain +4 Atk/Spd/Def/Res during combat if she is at 25% HP or above at the start of combat. However, that number increases if she has at least 3 Dragonflower stat boosts applied to her, with +1 for every boost she gets after 2 boosts, up to +7 Atk/Spd/Def/Res during combat with 5 or more Dragonflower stat boosts, and if she has at least 3, she can negate any field stat buffs the foe has during combat, meaning that her Lance will gain more effects if she has at least 3 Dragonflower boosts applied to her.
Mentor Archetype: Seth takes a stab at trying to teach Veronica that her people should come first. It seems to have had an effect on her.
It's possible to have multiple versions of the same character in one team.
You can have 3 different versions of Cordelianote Regular, Bridal, Summer, Olivianote Regular, Performing Arts, Ylissean Travelers, Kageronote Regular, Spring, Halloween, Sakuranote Regular, Halloween, Bath, Elisenote Regular, Summer, Bath, Hinokanote Regular, Wings of Fate, Bath, Fjormnote Regular, New Year's, Bridal, Gunnthránote Regular, New Year's, Summer, Laegjarnnote Regular, New Year's, Summer, Berkutnote Regular, Fallen, Dancing, Reinhardtnote Regular, World of Thracia, Dancing, Ninonote Regular, Scattered Fangs, Winter, Sharenanote Regular, Spring, New Year Duo (with Alfonse), Faenote Regular, Winter, Spring Duo (with Idunn), Caedanote Regular, Bridal, Young, Pallanote Regular, Spring, Young Duo (with Catria & Est), Estnote Regular, Spring, Young Duo (with Palla & Catria), Julianote Regular, Legendary, Fallen, Mianote Regular, Halloween, Summer Harmonized (with Masked Marth), Bylethnote Regular Male, Regular Female, Female Summer Duo (with Rhea), Niniannote Regular, Bridal, Halloween Harmonized (with Young Tiki), Dimitrinote Regular, Brave, Legendary, Sanakinote Regular, Bridal, Winter Harmonized (with Altina), Krisnote Regular Male, Regular Female, Plegian Male, Claudenote Regular, Brave, Legendary, Myrrhnote Regular, Halloween, Spring Harmonized (with Nah), Minervanote Regular, Young, Spring Inigo/Laslownote Fates Regular, Performing Arts, Spring, Tananote Regular, Summer, Young, Innesnote Regular, Summer, Young, and L'Arachelnote Regular, Halloween, Young fighting at once.

There are 9 variants for Corrinnote Regular Male Corrin, Regular Female Corrin, Summer Female Corrin, New Year's Male Corrin, Adrift Male Corrin, Adrift Female Corrin, Fallen Female Corrin, Fallen Male Corrin, Legendary Female Corrin.
Eleven special maps featuring several of these characters and their alts were available from late April to early May 2018.
There's also Legion's Grand Hero Battle, wherein the player faces multiple Legions.
As a nod to the final battle of Fates: Conquest, two copies of Fallen Takumi have to be taken out during his Grand Hero Battle.
When Freyja steps onto the scene as a boss during Book IV's story, multiple copies of her are out to hunt down the player's units. There's three copies of her, each with differing skills, and they get replaced by another one should one of them fall.
Mickey Mousing: The Book V movie has this, where everything is synced up with the music. In addition, compared to "Howling Gears", the Book V map music featuring the Niðavellir units, the movie's music has additional instruments played on certain parts to add emphasis to the actions onscreen, such as clanks and drops to add impact on both Alfonse and Reginn's attacks.
Mighty Glacier: Armored units. While their individual stats vary and they can be everything from a Stone Wall to a Lightning Bruiser, their defining characteristics are very high stat totals, and having the slowest movement type in the game, being only 1 space per turn. (With that said, there are some skills that allow them to move further on certain conditions.)
Modesty Shorts: The towel-wearing Ryoma from the Hostile Springs event is clearly wearing underwear under his towel; lucky for him as he also suffers a full Wardrobe Malfunction in his injured artwork. Camilla also wears something under her towel, which is only apparent when she gets a wardrobe malfunction as well.
Modesty Towel: Bath units do battle while wearing only their towels. It doesn't hinder them in the slightest.
All Forging Bonds cutscenes are set to a lively tune, which was inconspicuous at first, as the first few events were Slice of Life stories set around the Summoner getting to know the new Heroes. However, in darker, more serious stories, the music doesn't change.
In "The Sworn Oath", the Nifl royals discuss a coming war with Múspell (which is already depressing because it was released after the end of Book II), and Fjorm has a nightmare of Surtr burning her kingdom, all the while cheerful music plays in the background.
After Xenologue 1 is completed, a cutscene plays where Veronica asks the Mysterious Man to have tea with her. He declines and instead asks Veronica about how she's been feeling, which leads to her talking about a voice in her head that compels her to kill people.
This is also how more light-hearted Paralogues have succeeded dire Main Story chapters. Take, for example, the climax of Book II where Surtr manages to tank the spell that was supposed to kill him, rendering everything the Heroes did futile and leaving them fleeing for their lives... Come Paralogue 21, and it's back to Anna's hijinks, attempting to get a quick buck to keep the Order of Heroes afloat. Paralogue 27 is itself this compared to the previous Paralogues, tackling a young Azura's childhood neglect and escapism.
Money Multiplier: The skills Live for Honor and Live for Bounty respectively increase the amount of badges and shards/crystals obtained from Training Tower maps by 50%.
While it's more obvious with enemy Heroes summoned by Embla, even the Heroes (including villains!) you summon have a compulsion to trust you. Some voice confusion about it, but it is strong enough for them to not be bothered by it too much. Bring a character to 5-star rarity and level 40, and you earn that trust properly.
Camilla recognizes that she's under a compulsion; but she states she doesn't care. She's so starved for affection; she'll accept the "magic" loyalty and make it real.
Multiple Reference Pun: The weapon's name "It's Curtains..." has two meaning behind it: the first is it's Exactly What It Says on the Tin, being just bath entrance curtains on a wooden pole, and the second being part of the phrase "it's curtains for you", meaning that your show is over.
The Multiverse: Where you're implied to be plucking heroes from. For clarities sake this is different than the outrealms like the settings of all the previous games the heroes go to. FE does both the multiverse and other dimensions.
Mutually Exclusive Powerups: Legendary and Mythic Blessings are exclusive to each other due to blessing only having one slot, as the Mythic Blessing are only active in Aether Raids, while the Legendary Blessing are active everywhere else. Mythic Blessing, however, give more stat benefits than Legendary ones to compensate.
Paralogue 27: Adrift has normal Azura confront her Adrift variant, who appears as a young child. Nothing will keep you from teaming them up, however.
Edelgard, Dimitri, Claude, and Lysithea from Fire Emblem: Three Houses have their Pre- and Post-Time Skip versions available to the player, and they can be put onto the same team.
Both Lilina and Zephiel appear as their younger selves from Blazing Blade and their older selves from Binding Blade, in addition to the younger version of Hector and his epilogue version from the prequel, as well as units from The Start of it All and Childhood Encounter units with young version of heroes from Shadow Dragon and the Blade of Light and The Sacred Stones, respectively. All of them can team up with each other.
Also discussed by Legendary Lilina in one of her castle quotes, where she mentioned that she saw a younger version of Hector with a child, who she believes is her younger self, referencing Duo Halloween Hector and Lilina. However, this doesn't stop you from putting both of them in your team.
Lilina: I caught a glimpse of a young version of my father! He had a child with him. I think it might have been me...
The enemy team can consist of up to six units compared to the player's limit of four (five in Aether Raids). This does not take reinforcements into account, as they can arrive even if there are already a certain amount of enemies on the field.
In Aether Raids, the attacking team can trigger tile traps when they stop on them (either by movement or positioning assists), but the defenders cannot.
Tomes and Daggers in Fire Emblem are usually able to attack at melee range, but they lose this ability in Heroes for balance reasons. It's still possible to counterattack at melee range, but it requires skills such as Close Counter and Close Foil.
Stat debuffs now only last until a unit completes their next turn, rather than gradually recovering 1 point per turn like in Fates.
In Fates, Savage Blow inflicts Splash Damage on its user's opponent and other enemies within two spaces of the user's opponent. In Heroes, Savage Blow only inflicts Splash Damage on enemies within two spaces of its user's opponent.
Rally skills in Heroes target only one adjacent ally after movement, instead of affecting all allies within range of the user in Awakening (3 spaces away) and Fates (2 spaces away for the single version, 4 spaces away for Rally Spectrum). Slightly Downplayed with the Rally Up variants, which the stat boosts also affect any allies within 2 spaces of the ally target.
Raijinto, Siegfried, Gradivus, Ragnell, and Alondite lose their ability to attack from range, though they at least have built-in Distant Counter to counterattack at range. They also lose their passive stat bonuses.
The version of the Yato that male Corrin wields is the Omega Yato, which is Purposefully Overpowered in Fates. Heroes strips away (unrefined)/nerfs (refined) its passive stat bonuses and lowers its Might from 18 to 16.
Armored Blow and Warding Blow have their hefty Damage Reductionnote -10 physical damage for "Armored Blow", -20 magical damage for "Warding Blow" changed to giving a max of +6 to Defense and Resistance, respectively.
Wary Fighter, which prevents follow-up attacks for the enemy and user during combat, has a HP threshold to remain active (the lowest being 50%) and is now restricted to armored units only, instead of being always active and usable by everyone in Fates.
In their home games, Silvia, Lene, Reyson, Leanne, and Rafiel could refresh more than one unit at a time: Silvia, Lene, Rafiel, and Reyson could refresh all four adjacent units (Reyson only if transformed), while Leanne could refresh two units on opposite sides of her regardless of her state. In Heroes, however, they are reduced to one at a time like other singers and dancers in game.
In Fates, Kaden and Selkie are able to pass through forest tiles without any reduced movement if they're in their Kitsune/Nine Tails class. In Heroes, however, they are unable to even enter forest tiles thanks to them being classified as Cavalry units.
In Three Houses, Catherine's sword, Thunderbrand, was treated as a Brave weapon, allowing her to attack up to four times in battle. Heroes drops the Brave weapon classification, and instead lets her immediately follow up.
Never Trust a Trailer: This image shown in the Hall of Forms made it seem like Legendary Heroes were going to be featured, but as of November 2020, no Legendary Heroes have appeared at all and even though main protagonists have appeared, most of them are in seasonal get-ups or are in their normal outfits. Only three have been Brave heroes.
Nice Hat: The June 2018 update allows heroes to wear certain accessories, including a "hat" of Feh!
Nintendo Hard: Lunatic and Infernal difficulty maps can be this even by regular Fire Emblem standards. While Final Death isn't enforced in Heroes, the game makes up for it with many of the higher-difficulty enemies having higher stats - often higher than their playable incarnations can reach - that you must overcome with your 4-man team and only those four men. Even in the maps that don't require a No Casualties Run, losing a certain unit can snowball into a sudden defeat, forcing you to put a lot of thought into their actions and skillsets.
Enforced with the Hero maps, which will immediately end in failure if any allied unit loses all of their HP.
Some quests require the player to not lose any units on top of the other objectives.
Beating an Arena battle with all four of your allies will reward you with more points than if 1-3 of them were killed in battle, encouraging you not to lose any units while fighting and work around certain foes.
Squad Assault requires the player to utilize five teams with no duplicate Heroes across five consecutive maps to get a Sacred Seal and 2 orbs. Not one Hero on any of those five teams must fall, no matter the map.
Blessed Gardens started out the same as the Hero maps—clear one map without losing a single unit, except the Gardens only admit units with certain blessings or affinities. Eventually the Gardens gained an expansion in the Grounds, which are more akin to Squad Assault. The Grounds up the ante from clearing only one map to two or three maps while still requiring the player to keep their units (who, again, must have the right blessing or affinity) alive.
Downplayed in Tiers 29-38, collectively called "Vault of Heaven" in Aether Raids introduced in update 5.1.0, where players earn an extra 10 Lift if all their units are alive for each successful raid (+20 if the player uses the x2 boost), meaning while players can still earn Lift if they lose any units, even with heroes in the special slot in raiding parties, it's encouraged for players to keep all their units alive if they want to reach higher tiers in the Vault of Heaven and reach Tier 38 if they want to remain there for the next season.
Shards and crystals of five different colors are used to level up characters outside of battle, similar to the Bonus EXP mechanic from Fire Emblem: Path of Radiance and Fire Emblem: Radiant Dawn. Shards are used to level up characters below level 20, while crystals are used to level up characters that are level 20 and higher. While normally characters can only use shards or crystals that match their color, the yellow Universal Shards and Crystals can be used by anyone.
Healer characters get EXP for healing other units in addition to attacking enemies with their staves.
Averted with the dancers when they use the Dance/Sing/Play command, and any healer with the Rescue(+) support command, even though they can get EXP when doing that in the main games.
Although called a Duo Hero, the hero Young Duo Palla & Catria & Est are actually a trio of sisters.
No Pronunciation Guide: Generally averted. Units have several status page quotes, which play when you tap their portrait and are all voiced. For many characters this includes one line in which they introduce themselves by stating their name.
Characters drawn by Soeda Ippei (Arden, Dorcas, Walhart, Garon, Travant, and Darros) are rendered in a considerably more realistic style than the norm.
Downplayed with the characters drawn by Yamada Akihiro (Jagen, Ogma, Regular Zephiel, Gunter, Bantu, and Mila), Rebecca (drawn by Hoshino Lily), Regular Idunn (drawn by Yamada Kotaro), Legendary Seliph (drawn by Akira Egawa), and Guinivere (drawn by Asatani Tomoyo). While most characters' special attack portraits are edited versions of their normal attack portraits, these characters possess unique artwork for their special attacks.
Another downplayed example is characters drawn by Kozaki Yusuke, the artist for the Original Generation characters, starting from Brave Veronica. Unlike nearly every other character whose special art is derived from their normal attack art, Brave Veronica's pose for her special art is similar to her damaged art. Similarly, the characters he drew post-Brave Veronica (most notably characters from Books III and V) have near-identical attack and damaged artwork, while they all have unique special artwork.
Staff users cannot use their staves to heal themselves; there are some abilities that enable some degree of self-healing, but for those to work, their users need to heal one of their allies. Also, skills like the Hone, Fortify and Orders skills will buff allies adjacent to the character, but does nothing for the character themselves. The Opening skills raise the stats of an ally with the highest corresponding stat, the Joyous Lantern raises the Def and Res of an ally with the highest Atk at the start of their turn, and the Rapport Wand raises the Atk and Def of an ally with the highest Spd at the start of their turn, but does not include the user.
Laslow's Blade allows him to give the target ally as well as any allies within 2 space of the target ally +4 Atk/Spd/Def/Res if a positioning assist skill was either used by him or on him, but the +4 Atk/Spd/Def/Res do not apply on Laslow himself.
Averted with several skills and weapons. The Wave skills, Link skills, Legendary Tiki's With Everyone!, Legendary Roy's Human Virtue, Regular Fae's Eternal Breath, Armor March, the Joint Hone and Joint Drive skills, and the weapons Ardent Service and Fresh Bouquet all can boost the stats of their user and their user's allies.
The Dull Skills allows the user to ignore any field stat boosts on enemies during combat, with Dull Close ignoring boosts from enemies equipped with melee weapons, while Dull Ranged ignoring boosts from enemies with ranged weapons. Certain weapons, such as Divine Naga, Mulagir, and the inheritable 2018 Valentine weapons also has this effect, with different limitations, such as the 2018 Valentine weapons having the same conditions as Dull Ranged, the unrefined Mulagir being limited to Tome users only (the refined Mulagir having Dull Ranged), and Divine Naga having no weapon limitations. Because of this, they can ignore the Atk boost of weapons that get stronger the more bonuses the user has, such as the -blade tomes and Laevatein.
The Lull Skills allow the user to ignore any field stat boosts on enemies during combat, but only to two stats. However, it also inflicts a -3 stat debuff on those two stats on the foe during combat. They also work against any weapon type unlike with the Dull skills, but they're also only available on Infantry and Cavalry units. Altena's Earthly Gáe Bolg also has this effect, except it inflicts -5 Atk/Def instead and excludes both effects on flying foes. The Pirate's Pride and Unbound weapons and Blackfire Breath+ also has this effect, except it inflicts -5 to two of the foe's stats instead and only activates if the user is not adjacent to an ally. Seteth's Spear of Assal has a similar effect, with the user gaining +4 Atk/Spd during combat, as well as ignoring any field stat buffs to the foe's Atk and Spd during combat, if the user is within 2 spaces of an ally.
Hardy Bearing, as well as Yukata Micaiah's Dawn Suzu, the Festival in Hoshido daggers, Dragonslasher and Caltrop Dagger, and Legendary Lilina's Studied Forblaze negates any skills that both the user and foe has that changes attack priority, such as Vantage and Desperation, with only Studied Forblaze needing the user to be at 25% HP or more at the start of combat.
Null Follow-Up allows the user ignore skills that negate any of the user's follow-up attacks, and negates any skills that guarantees any of the enemy's follow-up attacks. Both Regular Byleths' Creator Sword, Legendary Celica's Soul of Zofia and Spring Fir's Bun-Bun Baton also has this effect, while Regular Mareeta's eponymous Sword, Young Merric's Winds of Change, and Dagr's Sun-Twin Wing need to meet certain conditions to gain this effect.
Both Regular Byleths' Creator Sword grant Null Follow-Up and also ignore skills that gives the foe +1 special buildup and inflict -1 special buildup to the user. The refined Ayra's Blade for Ayra only has the latter effect.
Mystic Boost and Splashy Bucket allows the user to ignore any enemy weapons and skills that target the user's lower defensive stats, and the Wrathful Staff effect from enemies. Close Ward, the exclusive refine on Naga, any refine on Divine Naga, Legendary and Fallen Julia's Light and Dark, and Guinivere's Aureola, only has the former effect, and in the latter's case, only if either the user initiates combat or there is an ally within 2 spaces of the user.
Null C-Disrupt allows the user to counterattack, regardless of the enemy's skills (like Dazzling Staff or Firesweep weapons) or status effects (mainly the one cast by Candlelight+/Flash+) on the user.
Regular Idunn's Demonic Breath and Brunnya's Fimbulvetr allows them to ignore any penalties they have, as well as gain +4 Atk/Spd/Def/Res, during combat, if they either have any negative status effect or is not at full HP before the start of combat.
Deadeye, Altina's Twin Blades and Young Innes' Bow of Frelia allows the user to ignore Damage Reduction from non-special skills such as Close Call and Brave Ike's Urvan when they activate.
Shannan's Balmung, Male Kris' Blade of Shadow, and Female Kris' Spear of Shadow allows the user to ignore any penalties they have, as well as grant the user +5 Atk/Spd/Def/Res during combat for Balmung, and inflict -5 Atk/Spd/Def on the foe during combat for Blade of Shadow and Spear of Shadow, if the foe is at full HP at the start of combat, or if the foe initiates combat.
Legendary Chrom's Randgríðr allows the user to ignore any penalties they have, as well as inflict -6 Atk/Def, during combat, if the foe is at full HP at start of combat.
Spring Est's Eagle's Egg, in addition to giving +5 Atk/Spd/Def/Res, allows the user to ignore any penalties they have if they are within 2 spaces of an ally. The 2020 Spring weapons, Steadfast weapons, and Pale Breath+, as well as the unique refine for Draug's Stalwart Sword have similar effects, only that it gives +5 Atk/Def to the user and ignore any penalties to those two stats. The unique refine for Shiro's Bright Naginata has a similar effect with Eagle's Egg, only that it gives +5 Atk/Def during combat with the same activation conditions.
Spring Duo Idunn & Fae's Zephyr Breath, in addition to inflicting -6 Atk and deny any follow-up attacks on the foe, allows the user to ignore any penalties they have if either they have a field stat buff or are within 2 spaces of an ally.
Bramimond's Impenetrable Dark allows the user to negate all foes skills, excluding the target, during combat, including skills such as the Drive skills, Brave Lucina's Geirskögul, and similar effects.
The unique refine for Setsuna's Yumi for Setsuna, in addition to granting +5 Atk/Spd, allows the user to ignore any penalties to their Atk/Spd during combat if the user has any buffs on them, such as any field stat buffs or positive status effects.
Slick Fighter, as well as Brave Hector's refined Maltet, in addition to having a guaranteed follow-up attack, allows the user to ignore any penalties on the user if the foe initiates combat and the user is at 25% HP or above at the start of combat. The unique refine for Regular Nowi's Purifying Breath has a similar effect, with it allowing the user to ignore any penalties on the user as well as granting +4 Atk/Spd/Def/Res during combat if the user is at 50% HP or more at the start of combat.
Ronan's Indignant Bow, in addition to gaining +6 Atk and inflicting -6 Atk on the foe during combat, allows the user to ignore both penalties to the user's Atk and field stat buffs on the foe's Atk during combat, if the foe either initiates combat or is at full HP at the start of combat. The unique refine for Lewyn's Forseti has a similar effect, where it allows the user to ignore any penalties to his Atk and Spd and field stat buffs to the foe's Atk and Spd, if the foe is at 75% HP or more at the start of combat.
Røkkr Sieges actually allows you to put some normally useless or underused skills to actually decent use, such as:
Obstruct, considered a joke of a skill in any other mode, can actually help keep the Røkkr from moving too far away, which is especially helpful if the Røkkr is a cavalry unit.
Breath of Life, while normally impractical and unreliable, is actually helpful in keeping your team topped off and healthy if your units are set up properly. One viable tactic is by having one unit deal most of the damage with a Brave weapon and three refreshers adjacent to them, with Breath of Life helping keep the refreshers healthy.
Guard isn't actually a bad skill, but has limited uses due to the strict HP requirement, but it's monumental in Røkkr Sieges to prevent the Røkkr from using their Special which would damage the unit's team and have the Røkkr swap places. As long as the unit with Guard (usually the main damage dealer) stays healthy and topped off themselves with the help of their allies or their own skills, you can keep the Røkkr from ever activating their Umbra Specials.
Sol and Noontime have good use in Aether Raids and endurance type maps, but here, they can be crucial in helping your units survive the match. Since the healing is scaled off of how much damage you do, and your damage is multiplied by massive amounts, a single use basically amounts to a full heal.
Astra boosts your damage by 150%, and while it's normally Awesome, but Impractical due to its high charge, units that can pull it off with enough Special acceleration will tear through the Røkkr, since the damage will scale incredibly high due to the damage multiplier.
The Falchion, the legendary weapon used by Marth, Lucina, Chrom, and Alm, is a 16 might weapon that is effective against dragons and has a built-in Renewal 2. Naturally, it functions as a check against dragon units such as Tiki and Fae, but with the advent of Skill Inheritance, players discovered that the Falchion's Renewal 2 stacks with an inherited Renewal 3, allowing for an average of 8.33 HP healed per turn. Coupled with Reciprocal Aid, Falchion users can now be turned into medic-type units with, until update 2.0.0, more potent healing than the game's actual healers. With the release of refinements for the Falchions, their innate Renewal can be upgraded to level 3, which will raise the healing average to 10 HP per turn if paired with the B-skill Renewal 3, and up to an average of 15 per turn with the Renewal 3 Sacred Seal.
Rival Domains maps are surprisingly useful for completing quests that require you to KO units of a certain type or with certain weapons. They have no stamina cost, the maps are larger and feature more units, the mode cycles through your brigade, and the 10 turns is always played out (provided neither your fortress or the enemy's is destroyed), so you can increase your counts quickly using them.
While certain Special Training maps are meant for specific unit types, their enemy composition means they can be useful for powerleveling other unit types. For example, Special Training: Bows can be useful for leveling melee units.
The Pegasus Flight and Wyvern Flight skills, which allows them to inflict -1 Atk/Def on the foe during combat for every 2 Res they have over the foe, up to -7 Atk/Def, if their Spd is not more than 7 lower than their foe at the start of combat for the former, and inflicts -1 Atk/Def on the foe during combat for every 2 Def they have over their foe, if their Spd is not more than 10 Spd lower than their foe at the start of combat for the latter, is intended for units with high Spd and Res and are riding pegasi or kinshi for the former and units with high Def and are riding wyverns for the latter to give them an edge during combat, with what their names imply. However, due to the restrictions only allowing flying units wielding a Sword, Lance, or Axe to inherit these skills, it doesn't prevent wyvern riders to get Pegasus Flight as well, the most who can make use of that being Regular Camilla and Ninja Laevatein, or pegasi or kinshi riders to get Wyvern Flight as well, the most who can make use of that being Subaki and New Year's Hríd, or even those not riding a mount at all for both of them, like Regular Altina or Mirabilis. Ironically, many other units riding pegasi have low to average Res, meaning that only a select few can even use the Pegasus Flight skill to its maximum potential, while Wyvern Flight has many users who can use it well, where the hero with the lowest base Def and rides a wyvern is Regular Camilla, who, ironically, is one of the best wyvern riders to use Pegasus Flight.
Zig-zagged. Between Normal, Hard, and Lunatic, the biggest differences are increased stats and levels and better skills for enemy units. Infernal and Abyssal, on the other hand, often change the enemy layout, and in some cases skill sets and added Sacred Seals, to quash strategies that work on lower difficulties.
The enemy heroes in Relay Defense. Expect to see absurd levels of stats on enemies on the 5th map and higher.
The enemy heroes in Mjölnir's Strike, the successor to Relay Defense. The higher you tier and power of your heroes are, the higher the stats enemies will be.
The enemies in Resonant Battle. The higher your Interval, the larger the stats of enemies will become, sometimes reaching absurd levels, where you could see enemies having multiple stats go above 50 and Atk values go above 80 on Advanced. This was later brought down to more reasonable stats in update 4.10.0, where only very few heroes have multiple non-HP and Atk stats go above 50 and have their Atk reach the 70s on Advanced.
Lunge, Drag Back, Hit and Run, Knock Back, Close Call, and Repel are restricted to melee units only, since ranged units using it in Heroes would create problems with unit and map design, such as a flying ranged unit with Lunge making some maps Unwinnable by Mistake if they get an enemy unit stuck in terrain, blocking the unit from moving, or Knock Back moving units diagonally, moving them 2 spaces instead of the intended 1, which would make that skill overpowered against melee armored units.
Dancers cannot chain Dance, Sing, or Play onto each other if both are equipped with either, likely to prevent infinite movement between the two units, either to escape enemy attacks, or reach themselves or another unit to attack an enemy across the map.
Flier units are unable to inherit Bowbreaker, likely due to being able to stop any follow-up attacks on their constant weakness if they were able to negate it as well as being able to take bow wielders out easier.
The Triangle Adept/-raven tome combination was a problem for colorless units, since the triangle advantage against colorless provided by -raven tomes would be enhanced by Triangle Adept, making colorless units virtually helpless against units with this combination. To counter this, the Cancel Affinity skill was added to prevent Triangle Adept/-raven tomes from completely dominating colorless heroes, and was released on a common summonable hero to boot (though staff users cannot inherit this skill). While colorless units are still at a disadvantage against units who only have -raven tomes, the Triangle Adept problem now only affects those without Cancel Affinity.
Heavy Blade, which gives the user +1 special buildup for each of the user' attacks if they're stronger than their foe during combat, is inheritable to all movement type, with the only restriction is that Staff users are unable to inherit it. However, Heavy Blade was commonly seen being inherited on Cavalry and Flying units thanks to their mobility, and as a result, allowed them to activate specials sooner such as Galeforce and Ignis, and units in that movement types have high Atk while still having good access of ways to get a guaranteed follow-up attack. When Flashing Blade was released later, which compares Spd instead of Atk, it had the restriction of only being limited to only Infantry and Armored units, likely as a result of what Heavy Blade did in the Meta Game.
Brave, Gem, Firesweep, -raven, and -blade weapons, as well as the Poison Dagger+ and Kitty Paddle+, were popular for players to inherit onto heroes to exploit their niche in the Meta Game early in the game's life. Upon the release of version 2.0.0 in December 2017, those weapons were the only ones which did not receive any refinements, even though unique weapons with the same effects as those skills released later on in updates, such as Regular Titania's Draconic Axe having the same effect as Emerald Axe+ and Roderick's Steady Lance having the same effect as Firesweep Lance+, did get refinements later on. The Ninja Katana/Yari/Masakari weapons, which are tweaked versions of the Brave weapons released in November 2020, received the same treatment due to fears of having them be refined to be just stronger versions of the Brave weapons.
"Duel" skills are Arena-centric passives that treat a unit's BST (Base Stat Total) as 170 (in addition to a +5 HP bonus) for the Tier 3 versions and 175 for Legendary and Mythic Heroes and 180 for all other heroes (in addition to the +5 HP and +2 Atk/Spd/Def/Res bonus) for the Tier 4 versions before factoring in skills or merges. This allows low-BST units to function in Arena modes without tanking Arena Score, giving them more options than running full teams of Armors all the time.note For reference, BST bins are done in counts of 5. Gen 2-3 melee Armor units, Gen 4 melee Infantry, and Gen 5 ranged Infantry and melee Flying units reach the 170 bin, while some Gen 2-3 melee Armor units, Gen 4 Armor, and Gen 5 melee Infantry can reach the 175 bin (especially with superassets and no superflaws for the former and Gen 4 ranged Armor), and only specific Gen 2-4 Armor, most Gen 5 Armor units, and some Gen 5 melee Infantry units can reach the 180 bin, with only a few naturally and the rest needing superassets and no superflaws.
The Røkkr's Umbra Burst and Umbra specials were attempts at countering trapping Røkkr units with player units. The Umbra Burst weapons will at least deal 1 damage per attack and have Distant/Close Counter built into them, and the Umbra specials allow them to deal damage to all enemies within 2 spaces of them after combat and switch places with their target after combat, giving them an escape mechanism should they be trapped. However, there are specific builds that allow players to still be able to trap them since the switch is Special-based.
The Guardian Seals enemy heroes have and item Seals that the Thieves have in Resonant Battles have effects that activate when the unit is defeated, with them restoring 10 HP and +1 special cooldown to the unit that defeated them after combat, intended to halt Galeforce, AOE specials, Wings of Mercy, and Escape Route builds that players can use to easily cheese the map, as well as the Guardian Seal acting as Obstruct for ranged foes as well. However, like the Røkkr above, there are a few heroes and strategies that still can ignore the Seal's intended effects.
Close Ward grants +5 Atk/Res to the user during combat if the foe uses a tome, staff, or is a dragon, and allows the user to counterattack against dragons. Dragons usually hit the lower of Def or Res against ranged units however, so Close Ward also disables that adaptive damage effect to ensure that it can actually work as intended.
Once a Season: Several seasonal banners have so far always followed a few patterns in terms of what unit types they feature, and consistently appear at their appropriate times, like Summer banners always appearing in June and July.
New Year's banners feature every type of unit except armoured units, and starting from the second NY banner and onward, they have featured units who are original to Heroes itself.
Valentine's banners feature at least two armoured units and two cavalry units, and usually follow the theme of familial love.
Spring banners feature at least one flying unit.
Summer banners feature every type of unit except armoured units. Also, summer banners pop up twice a year, with the second always following the first.
Dancer banners feature dancers, with every unit that's featured having refreshing abilities.
Halloween banners feature at least one armoured unit.
Winter banners usually feature at least two armoured units.
One-Gender Race: Dragon units used to be all female—including the generic Manakete enemies—until the arrival of the Fallen Heroes banner, which included Male Robin as a green armored dragon, and many more male Manaketes has been released since then.note Male Corrin is also a dragon in his home game, but in Heroes, is treated as a sword or (in his New Year's variant) bow user and thus isn't affected by dragon-related buffs or anti-dragon weapons.
The Choose Your Legends event usually do not change the names of some Japanese-only Fire Emblem characters. Therefore, there's both Arthur of Nohr and Arthur son of Tailtiu and the game does not bat an eye on this. The same can also be said of Hilda Valentin Goneril and Hilda of Friege, and even Lorenz of Grust and Lorenz Hellman Gloucester (the Lost Lore in Archanea featured the former Lorenz, and his name is written exactly like the latter). When you say their names in context of Heroes, you may want to be careful to not refer to the wrong person (though usually, fans only refer to the character that has been added to the game).
Fáfnir is both the name given to the generic flying dragon enemies, and the character who is the King of Niðavellir from Book V.
Only Six Faces: Some artists often use the same faces on their character arts, but are usually varied enough that they look different side-by-side. Fujiwara Ryo (character artist of Regular Male Robin, Seth, Halloween Jakob and Regular Joshua), however, has a bit of a reputation for suffering from Same Face Syndrome. While the individual pieces are quite well-drawn, looking at them side-by-side shows that the characters' faces only really differ by the color and scaling of their eyes.
Our Dragons Are Different: The Manaketes use their Dragonstones to transform between human and draconic forms here, just like in their respective games. While many have forms that resemble traditional western dragons, Fae's is covered with feathers while Corrin's vaguely resembles a qilin.
Out of Character: Invoked by Winter Tharja, who tries to act more "normally" in an attempt to win Robin over. It naturally fails, and even Robin himself wonders what's going on with her.
A lot of weapons are functionally identical to another weapon in Mt and effect, with the only difference being appearance, lore, and wielder. For instance, swords like Raijinto, Siegfried, Ragnell, and Alondite all have the Distant Counter effect, just like the lances Gradivus and Leiptr, or the axe Stout Tomahawk.
The Book II update introduced enemy dragon riders; they are functionally mostly identical to the previous enemy pegasus riders, differing only in their typical stats.note Dragon riders have more HP, Atk and Def, but less Spd and Res.
The Sanctuary of the Mages Tap Battle has generic Red Mages and Troubadours instead of Sword Fighters and Lance Cavaliers, but they play the same way as their physical brethren.
There are specials that have the same effects, such as Mayhem Aether, the unique special skill of Fallen Ike, is mechanically identical to the Radiant Aether skill used by Legendary and Valentine Ike.
Parent-Child Team: First generation characters from Genealogy, Awakening, and Fates can team up with their children. Then there's also characters from The Blazing Blade who can team up with their children from The Binding Blade, as well as parent characters like Rudolf, Greil, Mikoto, and Garon who can team up with their children. Hector and Lilina even team up in Paralogue 18, while Eliwood and Roy band together for Tempest Trials: Breath of Destiny.
Certain events are intended to introduce new mechanics such as the Defense Tiles in the Defensive Battles map, or to pit players against the character designer of Awakening and Fates, Yusuke Kozaki, in the Yusuke Kozaki Trials. However, because these event maps always pay out 4.6 Hero Merit per battle (the maximum for most maps in the game) and cost merely 5 stamina, players used these challenges to quickly accumulate Hero Merit.
The Chain Challenge also became a Hero Merit farm. Even the easiest maps will give a large amount of Hero Merit per character for only 30 stamina. Also, some players intentionally leave a 10-map Normal challenge uncleared because it is the easiest way to level up characters of level 30 or more, since clearing the challenge will reduce the experience and SP given on further attempts, and the reward for clearing the challenge is minimal. Clearing even just one map in the challenge will still allow you to keep the rewards from that map.
The Fire Emblem Warriors maps had numerous reinforcements or many more enemies than usual, and they were much weaker than even the typical fodder unit. This made them the best way to grind experience and SP while they were available. This was so beneficial to the player, that the devs eventually created the Special Training maps specifically for that purpose, as the Warriors maps were only available for a limited time.
Special Training maps contain many reinforcements and are tuned specifically to help train certain units, e.g. Special Training: Bows contains mostly flyers and bow units. As such, they are an effective way to powerlevel your units.
Since they were updated to cost zero stamina, Grand Hero Battle and Bound Hero Battle maps are the most efficient way to grind Hero Merit, stamina-wise.
The Perils of Being the Best: Chill Skills allow the user to debuff foes at the start of their turn with the highest stats on their team, with up to -7 to the foe with that highest stat with the single stat version, and -5 to two of the stats to the foe with the highest total sum with those two stats on their team with the dual stat version, such as Chill Def inflicting -7 Def on the foes with the highest Def, and Chill Atk/Spd inflicting -5 Atk/Spd to the foe with the highest total sum of their Atk and Spd. The Bright Shrine and Dark Shrine structures in Aether Raids have the same effects as the dual stat version, except it inflicts up to -8 to two of the stats depending on its level, with the Bright Shrine inflicting up to -8 Atk/Spd, and the Dark Shrine inflicting up to -8 Def/Res. Plegian Harmonized Dorothea & Lene's Fell Candelabra has the same effect as the single stat version, functioning as if they have Chill Atk, Chill Spd, Chill Def, and Chill Res, only applying -6 to each of those stats at the start of the user's turn.
Permanently Missable Content: Forging Bonds events have been, thus far, one-time-only limited time events. Want to read some of the best writing the game has to offer? Too bad, go find it on the internet, unless the specific one you missed was voted for a rerun at a later date.
Pink Girl, Blue Boy: The spring variants of Alfonse and Sharena have light blue and pink accents, respectively. This also applies to their New Year's kimonos: Alfonse's is blue, while Sharena's is pink.
Ally and Summoner supports give your units a stat bonus depending on the rank of the support.
The +10 HP and +4 Atk/Spd/Def/Res stat boosts for bonus units on Tempest Trials and Arena, which does not apply to defense teams.
The bonuses for certain areas and units in Grand Conquest applies to the player units, but not for the enemy.
After update 2.5.0, player units in Rival Domains and Grand Conquests can perform actions after they warp to camps and their own fort, but not the computer. However, on the highest Infernal difficulty in Grand Conquests, enemies will perform actions.
Only the player can use a Duo Hero's Duo Skill and Harmonized Hero's Harmonized Skill.
Legendary Leif's Meisterbogen prevents the foe from making a follow-up attack if he initiates combat, but this only works if a player is using him.
Popularity Power: Popularity is the main deciding factor in the Voting Gauntlet, since a team with more players has more chances to score points.
Life and Death grants its user up to +5 Atk/Spd for the 3rd tier and +7 Atk/Spd on the 4th tier, but also inflicts up to -5 Def/Res with the 3rd and 4th tier version.
On the opposite end, Fortress Def and Fortress Res grant +5 Def and +5 Res, respectively, while Fortress Def/Res 2 grants +4 Def/Res, but also inflict -3 Atk. Fortress Def/Res 3 grants +6 Def/Res, but inflicts only -2 Atk instead.
Fury 3 grants the user up to +3 Atk/Spd/Def/Res, but makes them take up to 6 damage after combat. Fury 4 has it go to +4 Atk/Spd/Def/Res, and take 8 damage after combat.
Firesweep weapons and Roderick's Steady Lance prevents the enemy from counterattacking, but the user cannot counterattack either.
Windsweep and Watersweep can prevent the enemy from counterattacking, but only if the user's Spd is higher and they initiate against specific weapon users, depending on what -sweep the user has equipped. They also prevent the user from doubling if he/she initiates combat, and will not protect the user from being doubled.
Lightning Breath(+) allows the user to counterattack even when attacked at a distance, but its Might is lower than other Breath attacks, and slows special charge by 1.
-blade tomes increase damage based on the amount of Status Buffs that the user has, but they also slow special charge by 1.
Weapons such as the Brave weapons, Dire Thunder, and Vafþrúðnir allow the user to attack twice regardless of Spd before the opponent can counterattack. On top of that, if the user has enough Spd to double, this leads to them attacking up to four times in a single round. However, the user also suffers either -2 or -5 Spd depending on the weapon, making it difficult to reach that quadruple attack threshold while also leaving the user more likely to get doubled themselves. The In The Moment weapons, as well as Duo Ninja Lyn & Florina's Tailwind Shuriken, instead gives the user +4 Spd and allows the user to attack twice if they initiate combat, making it easier to quadruple their attacks, but also inflicts -4 Def/Res on the user, making them more vulnerable enemy attacks as well. Lex's Goddess Axe allows the user to have +5 Def and attack twice, regardless of phase, but inflicts -5 Spd/Res, making the user more physically bulky, but still vulnerable to magic attacks. These weapons don't have the highest of Might, either.
Triangle Adept and the equivalent gem-based weapons (the Ruby Sword, Sapphire Lance, and Emerald Axe) amplify the Weapon Triangle's effect on both ends. This means when the user has the advantage, they will do 40% more damage to their opponents and take 40% less damage from them, but when they have the disadvantage, they will do 40% less damage to their opponents and take 40% more damage from them, as opposed to 20% in all cases.
The exclusive weapon refinement shared by the Basilikos and Solitary Blade gives "Life and Death 3" to the user, giving them more power at the cost of less durability. Combining this with "Life and Death 3/4" in their A Skill and Sacred Seal slot would make them a Glass Cannon, but it's Awesome, but Impractical for a reason.
Julius' Loptous tome gives him +3 Res and inflicts -6 Atk on an enemy that fights him without an anti-dragon weapon, but also makes him weak to anti-dragon weapons.
Fallen Berkut's Kriemhild allows him to deny any follow-up attacks as well as counterattack any ranged opponents that initiates on him if an ally is within 2 spaces of him, but instead of him receiving anything, the closest ally receives 20 damage after combat.
The Spendthrift Bow+ allows the user to gain +7 Atk and inflict -7 Atk on the foe during combat, but if the user has attacked, they get inflicted +2 special cooldown after combat.
The Slayer weapons became the first items added that objectively outclass their older counterparts. They're identical to Killer weapons but with higher Mt. Later on, the game also added stronger versions of the Anti-Armor weapons and the -wolf tomes. Thankfully, the same update allows units to upgrade their weaker weapons into the stronger versions without Skill Inheritance.
The increase of BST on many units released later in the game's life did not do wonders for some heroes, especially "Gen 1" heroes, but some heroes released earlier do standout from the competition, due to access to either exclusive skills or weapons that later heroes do not have.
Some heroes are just straight up weaker than later ones released, such as Finn and Canas, who were overshadowed by later released heroes such as Brave Eliwood for Finn, and Ewan and Miranda for Canas, and some at the same time are easier to summon than others on top of being statistically stronger, such as Kliff being stronger and more available to the seasonal-only Spring Lucina, and Regular Hilda, Gerik, and Pirate Darros being stronger and more available to the seasonal-only Spring Chrom.
Some are Downplayed examples, as while they have access to stronger stats, they do not have access to exclusive weapons, such as Summer Ylgr, Echidna, Gerik, and Ninja Hana being statistically stronger than Raven, but he still has access to his exclusive weapon Basilikos and its refines over them.
Other Downplayed examples are heroes who are stronger in their niche, but have at least one or two of their stats be lower than their competition, such as Regular Conrad being a better Res tank Lance Cavalier than Regular Berkut, Jagen and Mathilda before all three received their personal weapons and their refines, but he misses a few HP and Atk for Regular Berkut, a few Spd for Jagen, and a lot of Spd for Mathilda, which are sometimes vital for surviving against certain enemies.
There are Zigzagged examples, however, as they still have a niche due to their exclusive weapons even after all the heroes released later don't have access to, such as Jeorge and Masked Marth, as while Jeorge is statistically weaker than heroes such as Legendary Alm, Dancing Nephenee, Norne, Shinon, and in the case of Nephenee, access to Dance over him, he still has access to Parthia and its refines, and while Masked Marth is weaker than Astram statistically and skill inheritance wise, they still have access to Falchion, its refines, and refine evolution into the Sealed Falchion.
Even Dancers, who normally have less stats than their non-dancer Gen equivalents, are a Zigzagged example, as they still have access to Dance/Sing compared to later released heroes, and as such still stand out as support characters instead, such as Performing Arts Inigo being weaker than Thrasir, but he still has access to dance, and therefore can use the Dance-buffing and Cantrip skills.
At first, personal weapons typically had a secondary skill that was only as strong as a second tier skill. Later Special Weapons will usually have two skills that are on par with third tier skills or better. However, the older ones have a chance to catch up if an update allows them to be refined.
Regular Eliwood's unrefined Durandal (+4 Atk on player phase) and Regular Corrin's unrefined Yato (+4 Spd on player phase) were both powercrept by Siegbert's Dark Greatsword (+4 Atk and Spd on player phase). Eliwood's refined Durandal paid him back in kind later on (a flat +3 HP, and +10 Atk and +4 Spd on player phase), but the unique refine for Siegbert's Dark Greatsword later on was able stand on its own (+5 Atk/Spd and ignore enemy field stat buffs if the user is alone during combat).
Fallen and Legendary Robin's Expiration (Distant Counter and adaptive damage) were powercrept by Legendary Tiki's Divine Mist and Fallen Tiki's Razing Breath (Distant Counter, adaptive damage, and effective against dragons), as well as Sothis' Sublime Surge (Distant Counter, adaptive damage, and negates her dragon weaknesses) and Fallen Female Halloween Robin's Moonless Breath (Distant Counter, adaptive damage, and recover HP equal to 30% of the user's HP when they activate a special and are within 2 spaces of an ally).
The ranged swords Ragnell, Alondite, Raijinto, and Siegfried were all powercrept by Legendary Roy's Dragonbind, which is a ranged sword that deals effective damage against dragons, and Fallen Ike's Chaos Ragnell, which is a ranged sword that gains in-combat stat buffs equal to double the user's field stat debuffs.
Gradivus and Leiptr, two lances that have Distant Counter built in, are directly powercrept by Brave Dimitri's Moon Gradivus, which has Distant Counter and +1 special buildup per foe's attack.
Shiro's Bright Naginata (Sturdy Stance 2) was powercrept by Lukas' unique-refined Daybreak Lance (Sturdy Stance 2, +3 HP, and a Killer effect). The unique refine for Shiro's Bright Naginata however gave him on top of Sturdy Stance 2 an additional +5 Atk/Def and ignoring any penalties on those stats during combat if the user is within 2 spaces of an ally.
Dancer Berkut's Verðandi is a straight upgrade of Performing Arts Azura's Urðr and Ylissean Travelers Olivia's Skuld, giving +4 Atk/Spd/Def/Res to the target instead of Azura's and Olivia's +3.
Lloyd's Regal Blade, which gave +2 Atk/Spd during combat if the foe is at full HP at the start of combat, was powercreeped by both Sacred Memories Eirika's unrefined Glepnir and Regular L'Arachel's unrefined Ivaldi with +3 Atk/Spd with the same conditions and additional stat boosts, but was later able to be refined to get up to par with them, with the refined Regal Blade now giving +3 Atk/Spd. When Sacred Memories Eirika's Glepnir and Regular L'Arachel's Ivaldi later on got refines in later updates, it powercreeped Regal Blade again by increasing it to +4 Atk/Spd if the foe is at full HP for the former, and gives +3 Atk/Spd/Res if the foe is at 75% HP or above at the start of combat. However, the former two were powercreeped by weapons such as Perceval's Prized Lance and Young Minerva's Dragoon Axe, which gave +4 Atk/Spd/Def/Res in addition to inflicting -1 special buildup on the enemy per attack if the enemy is at full HP at the start of combat, Larcei's Edge from Larcei, which gives +4 Atk/Spd/Def/Res and ignore foe's field stat buffs during combat if the foe is at full HP or if the user is faster than the foe at the start of combat, and Shannan's Balmung, which gives +5 Atk/Spd/Def/Res and allows the user to ignore penalties inflicted on them during combat if the foe is at full HP or if the foe initiates combat.
The Brazen skills are far more effective than the Defiant skills. While Defiant skills boost one stat by 7 and only activate if the unit starts its turn with 50% HP or less, Brazen skills boost two stats by 7 and activate if the unit enters battle with 80% HP or less, even if it's the middle of the enemy's turn. Additionally, Brazen skills can stack with other stat boosts, aren't affected by Panic since the boost only applies in battle, and are unaffected by skills that ignore stat boosts since they only affect visible stat boosts. The only advantage Defiant skills have is that they trigger Blade tome, and the refined Regular Eirika's Sieglinde and Regular Kaden's Kitsune Fang boosts, as well as give an edge with skills that compare the user's specific stat with the foe's one before the start of combat.
The Color Duel Movement 3 skills are direct upgrades to HP+5; they give the same effect in addition to treating the unit as if they have 170 Base Stat Total for the purposes of Arena scoring. The Color Duel Movement 4 skills are also direct upgrades to HP+5 and the dual stat 2 skills as well, where they give +5 HP and +2 Atk/Spd/Def/Res as well as calculate their BST as if they have 175 on Legendary and Mythic heroes, and 180 BST for all other heroes in the competitive modes.
Repel and Close Call are direct upgrades over Knock Back and Hit and Run, respectively, as they have those effect alongside Damage Reduction if the user is faster than their foe during combat.
The Pledged Blade+ and Huge Fan+ from the 2020 Bridal banner are more powerful versions of Sandfort Spade+ and Shoreline Rake+ from the Summer Returns banner in 2019, where while both give +4 Atk/Def during combat if there is a [Bonus] on the user, the former two also give +1 special buildup per foe's attack with the same activation requirements.
The Ideal skills are more effective versions of the Push skills at Tier 1~3, where the Ideal skills gives up to +5 to two of the user's stats during combat if the user is either at full HP at the start of combat or has a [Bonus] applied to them, while the Push skills just need the user to be at full HP at the start of combat, but deals 1 damage to the user after combat. Averted with the Tier 4 versions, where they have different activation requirements while also being a big boon for certain heroes, with the Ideal 4 skills giving +7 to two of the user's stats during combat if the user is either at full HP at the start of combat or has a [Bonus] applied to them, and an additional +2 to those stats if both requirements are met, which is great for units that want to be healthy and rely on buffs, while the Push 4 skills give +7 to two of the user's stats if the user is at 25% HP or above at the start of combat, but deals 5 damage to the user after combat, which is great for units that want to be damaged to activate other skills and weapons.
Power Equals Rarity: You are less likely to obtain higher-star units when summoning, but they are generally more powerful than lower-star units.
Power Floats: Legendary and Halloween Fallen Female Robin, Yune, Naga, Brave and Bridal Micaiah, Altina, and Lilith are seen as units floating without using wings, which makes them fliers without a mount, much like units like Regular Myrrh and Summer Young Tiki.
Power Glows: The most powerful units, five-star units, have a faint golden glow around them, visible in combat, but most evident on the unit status screen. Characters with refined weapons also glow, the color depending on what type of upgrade they're using.
Legendary Heroes with the Battle Blessing and the last hero in your team in Allegiance Battles can pair up with other allies, which gives both the Legendary Hero and ally stat boosts, and the player can change between them at will, even if their turn is finished.
The -owl tomes, Regular Innes' Nidhogg, Katarina's Reese's Tome, and the unique refine for Regular Soren's Wind's Brand, Raigh's Hermit's Tome, gives +2 Atk/Spd/Def/Res during combat for each ally adjacent to them.
The Bond skills boost two of the user's stats by 5 during combat if they have an ally adjacent to them, while the Bond 4 skills increases them by +7 to two of the user's stats, as well as negating any penalties to those stats during combat. The exclusive refinement for Regular Chrom's, Regular Lucina's, and Masked Marth's Falchion has a similar effect, except it grants the user +4 Atk/Spd/Def/Res during combat. The -bloom weapons, Loyal Wreath, Faithful Axe and Heart's Blade grant the user +3 Atk/Spd/Def/Res under the same conditions. Adrift Camilla's Book of Dreams and Adrift Azura's Book of Shadows have the same activation conditions, except they inflicts -4 Atk/Spd/Def/Res to the foe during combat.
The Unity skills are a stronger versions of the Bond 3 skills, as while the +5 to two of the user's stats during combat are the same, the activation range is increased to 2 spaces, and any penalties on those stats are essentially reversed. For example, with Atk/Def Unity, if the user has -5 Atk and -7 Def, the user gains +10 Atk and +14 Def, essentially giving +5 Atk and +7 Def during combat, on top of the +5 Atk/Def from the base effect.
There are skills and weapons that give stat boosts to two of the user's during combat if the user has certain allies within 2 spaces of them, most of them being unique refines for personal weapons.

Pre-Mortem One-Liner: Like the 3DS Fire Emblem games onward, characters shout one of four lines when activating an offensive skill. Played with for healers; while they do shout lines, their skills don't trigger unless they're healing someone, and their offensive skill lines are only heard in the Catalog of Heroes and during Tap Battles.
Characters that had previously been unplayable antagonists and supporting characters in their home games can be recruited in Heroes as playable units. Naga, Duma, Rudolf, Mila, Annand, Díthorba, Reinhardt, Kempf, Veld, Idunn, Leila, Bramimond, Sonia, Greil, Yune, Altina, Jorge, Dheginsea, Mustafa, Iago, Garon, Mikoto, Lilith, Iago, Berkut, Rinea, Sothis, Kronya, Rhea/Seiros, Nemesis, and Solon in particular have never been controllable in any form, while the Death Knight made his first playable appearance in Heroes.

Rival Domains and Relay Defense has the player defend their fortress from being attacked 3 times by enemies, with the former also have the player attempt to destroy the enemy fortress to end the map. However, the battle ends when 10 turns have passed for the former, and 8 turns for the latter, and that players need to reach a certain score to actually win.
Subverted with Grand Conquest, where while the gameplay functions exactly like Rival Domains, the player does not need to defend the fortress from foes to prevent the player from losing, as it being destroyed ends the map instead and still gives score to the player.
Mjölnir's Strike, Relay Defense's successor, has the player defend two gateways from waves of enemies for 7 turns, with players having access structures in order to give them an edge.
Pun: The "New Year: ω Special Heroes" banner features the New Year variants of álfar units, and "ω" is the lowercase of Omega, or Ω. In other words, the Alpha and Omega.
Purple Is Powerful: A select number of Special weapons can be upgraded in the Weapon Refinery, with each having the selection of a unique refinement. If that unique refinement is equipped, the character with that weapon will gain a purple glow.
Purposely Overpowered: Some Heroes are a cut above others in the weapon and movement type they belong to, or perform a certain role better, but many Brave, Legendary, Mythic, Duo, and Harmonized Heroes are this on purpose due to their exclusive weapons, skills, and/or their optimized statline, such as Legendary Hector being better than some Axe Armored heroes, including Regular Hector.
Put on a Bus: On the side of the seasonal Paralogues, every single one after "Renewed Spirit" has no mention of the Order of Heroes at all in the narrative, instead focusing more on the featured characters themselves as opposed to the shenanigans of Anna, Sharena, and Alfonse.
Puzzle Boss: Tactics Drills give you specific units and a small number of turns to clear a level, usually by taking advantage of the limited skill set they have.

A Quest Giver Is You: The Lost Lore events have you sending units to locations in other worlds to collect story information about particular events that happened in that world. After a period of time, they return with lines and other items like badges and crystals.

Finish that, and your reward is a summary of an important event that happened in one of the world's games.
Ragtag Bunch of Misfits: Even by Fire Emblem standards, the Order of Heroes is weird.

The Dragonflowers introduced in update 3.2.0 give allies +1 to a single stat for each charge, up to 10 times for infantry introduced prior to 3.2.0, and 5 times for all other units.

Recurring Element: Since the Darker and Edgier Book II, there has been a banner featuring Fallen Heroes (which usually comes with a Grand Hero Battle as well).

For Book II, there's Hardin, Male Robin (as Grima), Celica and Takumi. In Book III, there's Mareeta (who got a normal version of herself later), Berkut, Corrin (Female), Tiki (Young) and Delthea. For Book IV, we have Ike, Corrin (Male), Lyon, Julia, and Ashnard.

Dancing Ishtar's Mögþrasir and Dancing Reinhardt's Vafþrúðnir are named after two Jotunn from Vafþrúðnismál, the third poem of Poetic Edda, whom the latter compete in a deadly contest of wits against Odin while mentioning the former once, and lost against Odin.

Unlike the other Brides, Lyndis is aghast towards the bride dress that she's forced to wear, insisting that there has to be an important reason why she's wearing that dress and it's totally not her idea.
Spring Catria does not appreciate having to wear a bunny outfit for the Spring Festival and mentions as much a lot.
Spring Catria: My desire to protect you is no laughing matter! Unlike this outfit...

Retcon: When the game first launched, Virion was the first hero you summoned during the Preface map "The Legend". After the 2.5.0 update, Regular Takumi is summoned instead. Virion still joins, but now he does so at the end of the map, along with Raigh and Matthew.
The boss music for certain Bound Hero Battles, such as Hawkeye & Ninian or Seliph & Julia, as well as the battle music in Heroic Ordeals, are direct rips of the player phase battle themes from the respective games the featured characters originate from.
The Tap Battles "Farewells" and "Heir of Light" use music from the games they're based on as boss music.
In Aether Raids, breaking Aether Fountains and Amphorae recovers Aether, the amount recovered depending on your lift tier, but only if you rout all the enemies within the time limit. Considering that you spend Aether on every attack raid, it's encouraged to go after them if you can.
The AR-O A Skills gives the unit if they're on the attacking raid team in Aether Raids stat boosts to 2 of their stats during combat, depending on how many defense structures are remaining on the enemy team, with 2 or less giving a substantial +10, 3 giving +7, 4 giving +4, and 5 or more just +1, so players are encouraged to destroy enemy structures to gain the maximum benefits of these skills.
Rock Beats Laser: The characters from Niðavellir fight in Mini-Mecha called Gullinbursti armed with machine guns and missiles, yet your sword-wielding characters can go toe-to-toe with them just fine.
Rocket-Tag Gameplay: The competitive modes such as Arena and Aether Raids all but requires one-round kills, especially if you want to win without casualties. If you can't one-shot an enemy hero, prepare to be one-shotted by them, especially if enemy dancers come into play.
