History Fanfic / Prytaneum

* RealityEnsues: Sure, fighting enemies AtopAMountainOfCorpses may look cool. But it makes it easy to lose balance and fall over.

* HealingFactor: Percy's canonical healing from water is dialed UpToEleven due to his increasing magic stat, allowing him to do absurd feats, such as [[spoiler:survive tanking two blasts from a Crozzo sword (although that one required help from [[HealingPotion health potions]] and [[HellHound Mrs O'Leary]]]]. Percy even points out how him being injured or maimed [[GoodThingYouCanHeal isn't really as big a deal for him as it may be for other people]].

* ReallyGetsAround: Poseidon, as per canon, which Percy complains made his mythology lessons with Chiron a bit too information and causes him to "tune out" certain myths as a result. He happily muses that at least he wasn't Thalia, who had [[AnythingThatMoves Zeus]] as her father. Judging by Hestia's snarky comment about them hitting on Thetis sounding like them, this hasn't changed.

The battle with Kronos goes horribly wrong and Percy Jackson ends up dying, only to wake up inside of the dungeon. When he gets free, he ends up going Hestia's Familia (taking Bell's place) and combs through the Dungeon in search of any of his friends who have survived.

* NewAbilityAddiction: After Welf achieved Level 2 and the gained the Blacksmith DA he stayed up all night smithing items with different properties. [[TheWorkoholic Percy]] is slightly bemused by it.

* NoKillLikeOverkill: To deal with the Level 6 attacking Aiz, Percy has Ryuu snatch up the girls before unloading one of Welf's [[FantasticNuke magic swords]] on the murderer. Then has Ryuu back it with her magic. Then drives Riptide into the ground to collapse it down and bury them. [[spoiler: Typically, it fails dramatically to kill her.]]

* HomeFieldAdvantage: Percy when in water.

* SuperSenses: All Adventurers have these, but Percy's sense of smell is strong enough to track individuals.

* AttackReflector: The purpose of Percy's Skill Thetis: A Plea To Hold Back Fate. WordOfGod is that at full charge with all nine layers it is capable of reflecting an attack on the level of [[PersonOfMassDestruction Riveria's]] [[KillItWithFire Rea Laevateinn]]. [[AwesomeButImpractical Good luck getting it charged that much.]]
* AwesomeButImpractical: Sure being able to create a personal hurricane is cool, but it also drains a large amount of power and runs the risk of injuring allies.

* BlessedWithSuck: Percy's "Despair" Skill. Causes the Dungeon to ZergRush him.

* CombatPragmatist: Percy.

* DishingOutDirt: Part of Percy's power-set is the ability to cause localized earthquakes.
* DoomMagnet: Percy as usual, which is only amplified by his "Despair" skill. Other Adventurers get monsters spawning in small groups on the early floors. Percy? ZergRush.

* FatalFlaw: Percy maintains his, the inability to abandon his friend. [[spoiiler:He let's Revis escape because every second he delayed her was one Riptide could use to get away.]]

* TheForceIsStrongWithThisOne: Percy can tell how strong an Adventurer is by their sheer presence.

** Mystery is an incredibly rare Developmental Ability which is highly sought after and poorly understood, it allows users to "activate a miracle" and craft magic items. It works best by synergizing with other Developmental Abilities and how it manifests depends on the user. Mystery allows Percy to make a variety of magic items. Initially he only makes Undine Silk, but he later learns to make a variety of other items, such as [[spoiler:Nectar, [[KillItWithFire Greek Fire]], [[InvisibilityCloak Chameleon Armour]], Sonic Arrows, knock off [[NighInvulnerability Nemean Lion skin]] and [[HealingFactor Golden Fleece]]]].

* NoKillLikeOverkill: To deal with the Level 6 attacking Aiz, Percy has Ryuu snatch up the girls before unloading one of Welf's magic swords on the murderer. Then has Ryuu back it with her magic. Then drives Riptide into the ground to collapse it down and bury them.

* StrongAsTheyNeedToBe: [[JustifiedTrope Actually justified]]. Percy's strength fluctuates and changes depending on which of his Skills and Abilities are activated by the situation, allowing him to range anywhere from mid-Level 2 to low-Level 5.

* TurnedAgainstTheirMasters: [[spoiler:It turns out that the Dungeon spawned Percy as a monster, or tried to but couldn't make him into one. Since then he's been pretty much antagonizing it.]]

--> '''[[spoiler:Riptide:]]]'''“Perseus… You kept me waiting.”

* ComicallyMissingThePoint: Upon being told by Lili that Crozzo magic swords are said to be powerful enough to dry up the sea, Percy's first reaction is to become concerned and ask why anybody would actually want to do that.

* StrongAsTheyNeedToBe: [[JustifiedTrope Actually justified]]. Percy's strength fluctuates and changes depending on which of his Skills and Abilities are activated by the situation, allowing him to range anywhere from mid-Level 3 to low-Level 5.

* DualWielding: Percy chooses to try this with Riptide and Annabeth's dagger, [[spoiler: at least until the latter is badly damaged]].

* SoftWater: Averted hard for anybody who isn't Percy. Welf is badly injured after falling 600 feet off a cliff into a lake, despite his reasonably high Stats as a Level 1, and theorises the only reason he wasn't worse off was that [[MakingASplash Percy]] noticed him falling and altered the properties of the water.

-> At the end of the Second Titanomachy, Percy found Hope to be in short supply. With Kronos unstopped, his friends dead or dying, and the gods falling one by one, it was hard to believe they still had a chance. But when Hestia sacrifices herself to give him ‘Hope’, there’s no reason not to take it, even if it costs him his life. But when he awakens…

* AttackReflector: The purpose of Percy’s Skill Thetis: A Plea To Hold Back Fate. WordOfGod is that at full charge with all nine layers it is capable of reflecting an attack on the level of [[PersonOfMassDestruction Riveria’s]] [[KillItWithFire Rea Laevateinn]]. [[AwesomeButImpractical Good luck getting it charged that much.]]

* BerserkButton: The Dungeon and its monsters REALLY don’t like it when Percy drains power from the Pantries.
* BlessedWithSuck: Percy’s “Despair” Skill. Causes the Dungeon to ZergRush him.

* CallBack: Percy tries to copy his father’s sending Typhon into Tartaros via a whirlpool on [[spoiler: the Black Goliath]], but eventually becomes too exhausted to complete it.

* ClothingDamage: Percy goes through armour like most people changes underwear, and in one chapter is explicitly stated that he left spare clothing at Wayland's shop because he “was tired of people staring at him while he waited half naked in line to change his Magic Stones in the Guild.

--> '''Percy:''' I was proud of my own swordsmanship too, of course, but pride wasn’t my flaw; I was willing to give him a fair fight, but only on the condition that I was sure I would win.
* ComicallyMissingThePoint: Upon being told by Lili that Crozzo magic swords are said to be powerful enough to dry up the sea, Percy’s first reaction is to become concerned and ask why anybody would actually want to do that.

** [[spoiler: Before he died (again) Daedalus entrusted a list of names to Uranus of people to watch out in the event they are reincarnated from the Dungeon. Additionally, he leaves the name “Quintus” as a way of letting Fels gain Percy’s trust.]]

* DidntSeeThatComing: [[spoiler: Percy knew the specs on the Goliath and tailored his strategies for dealing with the Black Goliath accordingly. He didn’t anticipate the Black Goliath having a BreathWeapon capable of striking through his defences. Things rapidly deteriorate from there.]]
* DoomMagnet: Percy as usual, which is only amplified by his “Despair” skill. Other Adventurers get monsters spawning in small groups on the early floors. Percy? ZergRush.
* DualWielding: Percy chooses to try this with Riptide and Annabeth’s dagger, [[spoiler: at least until the latter is badly damaged]].
* DungeonBypass: Mrs O’Leary can still Shadow Travel, which Percy uses to skip to floors he wants or avoid having to climb back through the high floors. Welf points out exactly how valuable this ability is.

* EyeScream: Kronos gets Annabeth’s dagger rammed through his eye socket in the prologue. It wasn’t enough to kill him, but it certainly distracted and infuriated him.

* FluffyTheTerrible: Mrs O’Leary, the friendly Hellhound the size of a garbage truck.

* HealingFactor: Percy's canonical healing from water is dialed UpToEleven due to his increasing magic stat, allowing him to do absurd feats, such as [[spoiler:survive tanking two blasts from a Crozzo sword (although that one required help from [[HealingPotion health potions]] and [[HellHound Mrs O'Leary]]]]. Percy even points out how him being injured or maimed [[GoodThingYouCanHeal isn’t really as big a deal for him as it may be for other people]].
* HeroicRROD: After Shadow Travelling too much Mrs O’Leary begins to lose her corporeal form. [[spoiler: Taking Hestia down to the 18th Floor to reinforce Percy after barely recovering from previously overusing her powers reduces her to a tiny fragile shadow.]]

** “Smothering” has Percy, Welf and Lili make it through to the 18th Floor Safe Zone without the Goliath spawning or the monsters following them. [[spoiler: Then the Dungeon summons the Black Goliath.]]

** Mystery is an incredibly rare Developmental Ability which is highly sought after and poorly understood, it allows users to “activate a miracle” and craft magic items. It works best by synergizing with other Developmental Abilities and how it manifests depends on the user. Mystery allows Percy to make a variety of magic items.

--> '''Percy:''' “Don’t pay attention when the gods do something stupid; it only encourages them. Just pretend they don’t exist.”

* NoBodyLeftBehind: The habit of Dungeon monsters ‘not’ to do this is a source of frustration for Percy, who is used to them turning into dust immediately after being killed.

* NotQuiteFlight: During the fight with [[spoiler: the Black Goliath]] Percy figures out how to mimic flight by willing water to stick to his skin and then controlling it, describing it as less being flight as “pushing the water I was holding myself with”.

* ReallyGetsAround: Poseidon, as per canon, which Percy complains made his mythology lessons with Chiron a bit too information and causes him to “tune out” certain myths as a result. He happily muses that at least he wasn’t Thalia, who had [[AnythingThatMoves Zeus]] as her father. Judging by Hestia’s snarky comment about them hitting on Thetis sounding like them, this hasn’t changed.

* RedBaron: Percy gets the Alias “Hound of the Goddess” after Freya interrupts the suggestions of embarrassing nicknames and musing how he reminds her of a cute puppy. Compared to the [[EmbarrassingNickname previous suggestions]] from [[JerkassGods the gods]] he definitely got lucky.

* RoaringRampageOfRevenge: Ryuu’s canon rampage turns out to have been against Evilus, and everybody [[ThereIsNoKillLikeOverkill even remotely associated with them got destroyed]]. When she finds out that some of them may have survived she doesn’t take it well.
* RunningGag: Percy’s ability to constantly ruin his armour in early chapters.

* SoftWater: Averted hard for anybody who isn’t Percy. Welf is badly injured after falling 600 feet off a cliff into a lake, despite his reasonably high Stats as a Level 1, and theorises the only reason he wasn’t worse off was that [[MakingASplash Percy]] noticed him falling and altered the properties of the water.
* ShoutOut: Wayland, a member of Hephaestus’ familia, is one to Wayland the Smith from NorseMythology

* StrongAsTheyNeedToBe: [[JustifiedTrope Actually justified]]. Percy’s strength fluctuates and changes depending on which of his Skills and Abilities are activated by the situation, allowing him to range anywhere from mid-Level 3 to low-Level 5.

* SuperEmpowering: An ''unintentional'' variant. Percy’s Hero DA supports and inspires heroic actions in himself and others, making people around him more likely to [[SuperpowerLottery develop heroic Rare Skills and even magic]].

** Hestia points out that his own magic is closer to the gods’ own Arcanum, either activating automatically or with no chant (or even a verbal trigger) required.

* ThereIsNoKillLikeOverkill: The Dungeon’s typical reaction to Percy is to throw ludicrous amounts of monsters at him. When he first arrives on Floor 11 he the Dungeon sets an Infant Dragon, a Level 2 monster known for slaughtering entire teams of Level 1s, on him. When that doesn't work? It proceeds to spawn three more (there are only five of them in total), summon other monsters from every wall and direct the Minotaurs (also Level 2 monsters) fleeing from the Loki Familia towards him.

--> '''Cassandra:''' "When the dragon wakes, everything will burn. For seven days and seven nights, it’ll burn, and no blade will stand before it."
* VillainousBreakdown: [[spoiler: Zanis completely loses it after Mrs O’Leary takes his hand off. He even unleashes his stolen Crozzo magic sword in the middle of Orario, killing a significant number of his own Familia members as well as collateral damage to the surrounding area of the city.]]

* WreckedWeapon: [[spoiler: Annabeth’s dagger was badly damaged after Zanis uses his stolen Crozzo magic sword, [[KillItWithFire Kazuki]], on Percy. Welf is holding onto it until his Blacksmithing is high enough to repair it in a way that does it justice.]]

* FirstEpisodeResurrection /FirstChapterDisplacement: The prologue has Percy stabbed through his AchillesHeel by Kronos and dying as Olympus is destroyed. In the first chapter he wakes up inside the walls of the Dungeon.

** Bleeds into CursedWithAwesome via HadToBeSharp. Percy, and everyone with him, gets continuous TrainingFromHell, as long as they're in the dungeon...
