History YMMV / NightOfTheFullMoon

* TearJerker: The true ending of chapter 4, [[spoiler:Red crying onto the cover of the storybook as she closes it after the Little Carpenter dies saving her life.]]

* TheWoobie: The Little Carpenter. [[spoiler:Born a werewolf from his parents' forbidden romance and left as a DoorstopBaby, he was [[AllOfTheOtherReindeer bullied by the other kids when he was a child]]. The only one who would stand up for him and [[OnlyFriend be his friend]] was Little Red, but when an early moonrise on the night of full moon caused him to start transforming while in the village, he had to run away from her and hide in a miserable cave in the depths of the Dark Forest all night long while listening to her desperately calling out to and searching for him. Despite his strong feelings for her, [[CannotSpitItOut he can't confess]] because of [[InsecureLoveInterest his fear of her finding out his secret and possibly rejecting him]], so he continues to hide in the forest every full moon night — which unfortunately leads to a tragic encounter when Red is forced to search the woods herself for her missing grandmother and, oblivious to his identity, singles "the Big Bad Wolf" out as a possible culprit. If you get the true ending, she instead finds out his secret and realises he's not guilty, [[HopeSpot apparently accepting him despite his curse]] — but in the end, [[YankTheDogsChain he dies]] [[HeroicSacrifice saving Red's life]] from the explosion of the Nature Spirit.]]

* GameBreaker: Like with many card games, there are some incredibly powerful cards that should prove useful for clearing the game.

* TierInducedScrappy:
** The Nun is unquestionably the weakest class in the game; like all classes she has a number of strategies available to her (healing, prayers, Confession stacking) but she doesn't have as many blatant GameBreaker combinations available to her as the other classes, with very few to no ways of winning a battle quickly. She has a large number of really bad matchups against some of the more gimmicky enemies, such as against the Jungle Giant, and is consequently the class you'll lose on the most often. Possibly this is the reason the Apothecary (a DLC class in the Full Moon campaign) was made the 4th playable class in the Red Hood Diaries campaign rather than the Nun. On the other hand, this is part of the reason ''why'' she's so weak, as she didn't gain access to any new tools like the other base classes (Knight, Ranger and Witch) did from the Red Hood Diaries.
*** However, she did get some new buff in an update, even getting the most new cards out of everyone in said update. Thanks to all those new cards, a dedicated Prayer deck can put the hurt on an enemy real fast thanks to cards like Divine Portrait (Equipment that gives you 1 confession when a prayer's counter goes down by one), Holy Scepter (activates all prayers in your deck at their highest counter), and simple cards that lower the countdown of those Prayer Cards
** The Apothecary herself, while much more effective in the Red Hood Diaries, struggles ''really'' hard in the Full Moon campaign because of [[MagikarpPower her atrocious early game]]. Her starting deck is by far the worst of any class, with all her default cards being individually really weak, and if she can't quickly put together a viable way of doing damage from her starter blessing, chest cards and Grimalkin Shop offers, she will eventually find herself unable to even muster enough power to make it past the chapter 1 boss. She has about 3 different build paths, but they're all combo-dependant with almost ''no'' crossover between them, so any cards or blessings you pick up for one path will be almost useless (and in fact only get in the way) of making any other ones work (cards that increase your maximum HP are effectively meaningless if the rest of your deck is built around lightning combos or condition stacking).

** The Mechanic's ''Mechanical Transmission'' is so ''comically'' broken that it's ridiculous. It's an Exhausted card, one of a series of cards that all give you +1 action and then spend ALL of your actions to generate an increasingly-powerful effect depending on how many actions you spent on it. Mechanical Transmission's effect? ''Replicate the effects of every other Exhausted card in your deck at once!'' The idea of Exhausted cards is that they're all-in cards, of which you can only play one per turn to generate one massive effect, with all the others only being able to generate a minimal 1-proc effect if you play them as well, but Mechancial Transmission effectively lets you fire off ''several turns'' worth of full power effects, completely inverting the entire ''concept'' of Exhausted. Once you have even a couple of base actions to spend and a couple of other Exhausted cards (like Energy Bombing, Current Injection and Repair Wrench) in your deck, Mechanical Transmission is so broken that it will generally one-shot almost ''any'' enemy on its own, and even take a massive chunk out of bosses with minimal effort.
** One of the most fundamental cases is the common attack card Storm Strike, which is available to the Lady Knight and Magician as well as being used by many ([[DemonicSpider of the most troublesome]]) enemies. All it does is inflict 4/6 Lightning damage and increase all further damage the user inflicts that turn by 1. The thing is, being an attack card it costs nothing to use, and it ''stacks.'' Combining multiple copies with multi-hitting effects like Omnislice or Lethal Weapon and you can do ''outrageous'' amounts of damage very easily. This is also what makes the enemies who like to spam it against you (like the Ghost Captin or the Feral Child) so dangerous, and they can easily chew through practically your entire HP bar in only a single turn- and then do it again the next one!

** The Black Rose can be really problematic for certain classes, mainly because of her passive which causes you to lose ''all'' actions ''and'' mana the first time in a turn you play ''any'' card that inflicts damage on her- even if it doesn't actually inflict damage when you play it (like various counter cards)! Highly annoying for action-based decks, it's ''crippling'' for mana-based decks who don't regain all their mana at the start of each round like you do with actions. Classes that rely on spamming multiple low-damage spells to add up to a bigger effect (like Apothecary or Conjurer) can have a ''nightmare'' of a time bringing her down before she kills them- which is something that will only take a few turns, as her entire attack strategy is basd around spamming absurd amounts of poison onto you until you're taking 20-30 damage per turn, far more than any but the tankiest of builds can hope to survive.

** The Soul Hunter can use ''Soul Extraction'' to permanently steal any enemy card. Find a copy in chapter 1, and you may get a chance to lift ''Deadly Virus'' from the Mad Apothecary. Play it, survive four turns, and unless the enemy can AutoRevive you win. (However, you'd better have a backup plan, as enemies who ''can'' auto-revive like the Witch will promptly do so, while [[ItOnlyWorksOnce you only get one copy of the Virus]], forcing you to take their second life conventionally. Using it against the Headless Horseman is also [[HoistByHisOwnPetard the easiest way to commit suicide]] due to its Obsession ability reflecting all overkill damage back at you- and since the Virus hits for 999, that's a ''lot'' of overkill.)

** "The Weak Body" is also absurdly difficult, requiring you to get a combined 999 stacks of debuffs (Poisoned/Chilled/Burned/Stuck) on an enemy at once. There is basically precisely ''one'' way of completing this, and it requires a ''very'' [[GuideDangIt specific setup]]: a Witch build utilising multiple sources of poison, the ''extremely'' rare spell Wither (which doubles all stacks of Poison on the target before adding 8 more), the less-rare spell Toxicity Spread, which applies a number of Chilled stacks equal to the number of Poisoned stacks on the target before adding 3 more, and some way of multiplying the effects or generating duplicate copies of both spells. The problem is that Wither is very, very, ''very'' rare- you can easily do 5 or 6 runs through the Full Moon campaign, visiting every single Grimalkin Shop and opening every single chest along the way, and not be able to obtain a ''single'' copy, and without it you're wasting your time- there's simply no way to build up the requisite number of Poison stacks ''without'' its multiplicative effects (pretty much any enemy in the game will simply ''die'' from the poison long before you can reach 999- assuming you don't die yourself first). While not ''quite'' as bad as the above examples, the achievement still only has a global completion of 2.3% on Steam.

** "Save the Black Forest" requires you to defeat the TrueFinalBoss, [[spoiler:the Nature Spirit]], in a ''single turn.'' There's a number of these achievements for different bosses in the game, but this is definitely the hardest; aside from its mammoth HP pool, it also has a unique gimmick where the first time you bring it down it revives and corrupts half the cards in your deck. Appropriately enough, the achievement icon is a ShoutOut to ''VideoGame/DarkSouls''. Despite being available to players of the free version of the game (albeit added in an expansion update that a lot of old players will have missed), both of these achievements have a global completion rate of only ''0.8%'' on UsefulNotes/{{Steam}}.
** Another one that's particularly difficult is "Curse Purification" which requires you to take the monster abilities from the other 3 story bosses in the Red Hood Diaries and defeat Midas with them. The cards, abilities and blessings you unlock from defeating opponents in the campaign can be selected at the start of a run to improve your chances, but the skill you get from the Vampire Lord (which does nothing), the card you get from the Viper Queen (which also does nothing, effectively a Prank card) and the blessing you get from Black Swan (lose 1 health for every card you play) do nothing except [[SelfImposedChallenge make your run harder]]. To make matters worse, you can only face Midas as the final boss on a Hard V run, the highest level of difficulty. With the additional handicaps of the useless and ''actively harmful'' boss abilities, an already difficult boss becomes almost unbeatable, which is why the achievement only has a 1% global completion rate on Steam.
** "The Weak Body" is also absurdly difficult, requiring you to get a combined 999 stacks of debuffs (Poisoned/Chilled/Burned/Stuck) on an enemy at once. Quite aside from the fact that literally ''only'' the Apothecary or an extremely dedicated Poison/Frost Witch has any chance of completing this one, it's still borderline impossible, largely because without certain specific blessings, all debuffs except Poisoned are either consumed by the enemy's actions on their turn or simply go away at the end of turn anyway (Poison simply loses 1 stack every turn), so you have to either rack up all those stacks in ''one turn,'' or find a way to take multiple turns back-to-back (for the Apothecary this means exploiting the AwesomeButImpractical Mercury Hourglass, while the Witch can use Absolute Zero, which is much easier but also has the unfortunate side effect of consuming the Chilled stacks she's trying to rack up). While not ''quite'' as bad as the above examples, the achievement still only has a global completion of 1.8% on Steam.

** The [[SmashMook Jungle Giant]], while an easy encounter for most classes, can be almost impossible for the Nun to defeat. He has a unique gimmick where he only draws cards at the ''end'' of his turn, drawing an additional one each time, and his entire deck is made up of the high-damage Attack card Crush, but he discards a card whenever he gets hit. All the other classes can easily hit him enough times with {{Spam Attack}}s to make him discard his entire hand before he can bludgeon them to death- but the Nun's GradualGrinder style is uniquely unsuited to this requirement, and can't generate enough separate instances of damage to be able to make him repeatedly empty his hand before he can flatten her, while her healing and armour gain can't even ''begin'' to keep up with the barrage of Crushes, her Prayers don't have enough time to trigger unless they're set so low that they have minimal effect, and her Confessions only apply a single proc of damage, which isn't enough to chew through [[StoneWall his massive HP pool]] for the stage of the game he appears at.

** The Nun is unquestionably the weakest class in the game; like all classes she has a number of strategies available to her (healing, prayers, Confession stacking) but they all come down to some form of GradualGrinder, and she doesn't have as many blatant GameBreaker combinations available to her as the other classes, with very few to no ways of winning a battle quickly. She has a large number of really bad matchups against some of the more gimmicky enemies, such as against the Jungle Giant, and is consequently the class you'll lose on the most often. Possibly this is the reason the Apothecary (a DLC class in the Full Moon campaign) was made the 4th playable class in the Red Hood Diaries campaign rather than the Nun. On the other hand, this is part of the reason ''why'' she's so weak, as she didn't gain access to any new tools like the other base classes (Knight, Ranger and Witch) did from the Red Hood Diaries.

** The Headless Horseman can absorb a ridiculous amount of damage due to the fact that the first two times you defeat him he instantly revives with reduced HP. An extra nasty wrinkle to this is his Obsession buff, which causes any overkill damage you do to him (''including'' damage done on the hits that cause him to revive) to be reflected onto you instead- and if this kills you, you ''lose,'' even if the damage was [[KaizoTrap from the hit that finished him off for good]]. Decks that are able to build up huge bursts of damage (like Judgement-based Soul Hunters and their massive damage Death Comes spells) can easily end up killing themselves if they don't (or aren't able to) calculate their damage carefully to bring him down with the minimum of overkill. Making matters worse, his offence is almost entirely based around stacking up Confession, which does increasing amounts of piercing damage at the end of each of his turns, and unlike with the Priest, this does ''not'' reset every time he revives himself, so if you take too much time trying to work around his Obsession (or simply being unable to chew through his ridiculous combined HP total) you will inevitably lose to his unpreventable damage.
** The Poker Soldier poses a unique problem to some decks due to lacking a deck of its own; It deals large amounts of damage automatically each turn. Cards like Prank and Fear can’t slow it down, counter cards have nothing to respond to, and status effects like Burn never trigger. Basically, any deck that favors the indirect approach is going to have a hard time.

** "Save the Black Forest" requires you to defeat the TrueFinalBoss, [[spoiler:the Nature Spirit]], in a ''single turn.'' There's a number of these achievements for different bosses in the game, but this is definitely the hardest; aside from its mammoth HP pool, it also has a unique gimmick where the first time you bring it down it revives and corrupts half the cards in your deck.

Despite being available to players of the free version of the game, both of these achievements have a global completion rate of only ''0.8%'' on UsefulNotes/{{Steam}}.

* BreatherBoss: The Sword in the Stone is this. It's main gimmick is that the leftmost card in your hand becomes an exact copy of the last card that you use. This obviously works to your advantage, allowing you to, for example, spam cards with powerful effects that you only have 1 or 2 copy of or draw your entire deck out while still dealing damage to the Sword in the Stone. Also, while the boss's deck sounds pretty scary on paper, since it has a lot of Storm Strikes it can copy along with some Basic Attacks, it's ability does not activate for it, meaning you're the only one who gets to benefit from it.

** The [[SmashMook Jungle Giant]], while an easy encounter for most classes, is almost impossible for the Nun to defeat. He has a unique gimmick where he only draws cards at the ''end'' of his turn, drawing an additional one each time, and his entire deck is made up of the high-damage Attack card Crush, but he discards a card whenever he gets hit.

Possibly this is the reason the Apothecary (a DLC class in the Full Moon campaign) was made the 4th playable class in the Red Hood Diaries campaign rather than the Nun.

** Speaking of Witches: the Absolute Zero blessing removes stacks of Chilled from the enemy to give the Little Witch extra turns[[note]]First 5 stacks, then 10, then 15, and so on[[/note]]. Frost Nova can inflict a whopping 20 stacks, and there are a few ways to double that. Put it all together, and it can net you at least three turns in a row before your opponent thaws out. More if you can add enough stacks.
** And speaking of Witch Blessings that deal with Chill, the Ice Flame Bonfire is simply ''amazing,'' largely because it provides 2 different effects at once. Inflicting 6 free stacks of Chill on the enemy at the start of each turn, while very useful, is the ''lesser'' of the two, as it also grants you 2 free stacks of Pyro as well, which increases ''every'' instance of Fire damage you deal by your number of stacks. Pyro is a very powerful effect, but can normally only be increased by the Attack card Flickering Flames or the Mana card Magic Flames, which can make it hard to stack up enough, which the Ice Flame Bonfire trivialises. While not that impressive with most main Fire spells, which only inflict a single large instance of damage, when you [[GatheringSteam let it accumulate enough]] then an effect that can apply multiple repeated instances like the mana card Piercing Spell (3 instances of 1 damage) or the spell Firewall or equipment card Blazing Cloak (2 damage every time the enemy plays an Attack card) it can rack up ''insane'' amounts of damage.
** The Witch has a lot of these, really. Another possibility is weaponizing Cross Magic; on its own, the blessing causes you to gain twice your base mana at the start of each fight. Every two mana you gain triggers the Magic Staff for one physical damage, which in turn can trigger a Torch for one fire damage, and you can equip multiple copies of either. Build your base mana high enough, and this setup can near-kill most enemies before you even get to play a card.
** The Soul Hunter can use Soul Extraction to permanently steal any enemy card. Find a copy in chapter 1, and you may get a chance to lift Deadly Virus from the Mad Apothecary. Play it, survive four turns, and unless the enemy can AutoRevive you win. (However, you'd better have a backup plan, as enemies who ''can'' auto-revive like the Witch will promptly do so, while [[ItOnlyWorksOnce you only get one copy of the Virus]], forcing you to take their second life conventionally. Using it against the Headless Horseman is also [[HoistByHisOwnPetard the easiest way to commit suicide]] due to its Obsession ability reflecting all overkill damage back at you- and since the Virus hits for 999, that's a ''lot'' of overkill.)
** Wolf’s Roar as the Werewolf is useful on its own, preventing enemies from playing your choice of attack, action, or spell cards for two turns. But play a copy of Paranoia first, and it’ll lock down all three at once. Find or clone multiple copies of Wolf’s Roar, and your prey can’t do much but stand there while you rip them to shreds.
** [[LifeDrain Damage-based healing]] from the Vampire Sword equipment or the Vampire Codex Pandora Blessing. High-damage builds can suffer from attrition really badly against tanky opponents, especially in higher difficulty stages where healing from level-ups and healing encounters is reduced, but the ability to recover HP when you damage the opponent can easily trivialise almost any threat by exploiting the HealthDamageAsymmetry to repeatedly heal you to full health in one turn's worth of blasting.
** The Mechanic's Mechanical Transmission is so ''comically'' broken that it's ridiculous. It's an Exhausted card, one of a series of cards that all give you +1 action and then spend ALL of your actions to generate an increasingly-powerful effect depending on how many actions you spent on it. Mechanical Transmission's effect? ''Trigger every other Exhausted card in your deck!''
