->''"I swear with words not yet written, on gods not yet born... I will never run away again."''
-->-- '''Kin''', ''Webcomic/{{Goblins}}''

Most protagonists are depicted as imperfect; though heroic, they aren't flawless paragons of perfection, and will have some minor shortcomings to help the audience identify with them better. [=SuperBob=] can selflessly save the world on a daily basis, but mild-mannered Bob Trope will regularly leave the refrigerator door open.

Even so, some characters make a Heroic Vow: a commitment or standard that they ''will not cross'' for whatever reason. Perhaps it's [[ThePromise a promise]] to a dear one, a sense of pride, a personal MoralEventHorizon, or just because the hero is a NiceGuy. If a villain takes vows, it's usually because EvenEvilHasStandards.

Key to the Heroic Vow is that it is a commitment the character keeps because he willingly '''wants''' to. There are no talismans or fail-safes preventing the breaking of the vow, nor are they needed -- the character's willpower and resolve are the only requirements.

Note that the Heroic Vow doesn't necessarily have to be spoken (or written); a hero's behavior enforced with sheer [[HeroicWillpower personal willpower]] counts. If the vow ''is'' spoken/written, it may become a BadassCreed.

Some Heroic Vows are so commonplace, they have their own tropes:
* CelibateHero (will not have [[VowOfCelibacy romantic or sexual relationships]])
* DoesntLikeGuns (will not use firearms)
* NeverHurtAnInnocent
* ThouShaltNotKill (will not commit murder -- sometimes won't kill ''anything'')
* WouldntHurtAChild
* WouldntHitAGirl
* Not using a DangerousForbiddenTechnique is frequently requested by a {{Mentor}} or MoralityChain, or self imposed after seeing the potential consequences.

Often an application of HeroicSpirit, and popular with a KnightInSourArmor. When done well, can lead to [[SugarWiki/MomentOfAwesome Moments of Awesome]]. When handled poorly, can result in HonorBeforeReason, StupidGood, or SeriousBusiness. If a hero becomes obsessed with enforcing his Heroic Vow, he may end up becoming TheFettered. If unlucky, they'll be forced to make their vow a FrequentlyBrokenUnbreakableVow when circumstances force them to break it.

A convenient [[NarrativeDevices Narrative Device]] to drive a story in a direction it wouldn't normally go. Sometimes used to deliver AnAesop on morality. If the character is forced into breaking the Heroic Vow, expect a {{Heroic BSOD}}. If his determination to keep his vow starts to slip, it can be a prelude to JumpingOffTheSlipperySlope.

Compare and contrast with EmptyPromise, IGaveMyWord, PinkySwear, and ExactWords. When someone has broken this vow so thoroughly they become ostracised they're TheOathBreaker. If the oath is strong enough to prevent even mind control from forcing them to break it, it's an IntrinsicVow.



[[folder:Anime & Manga]]
* Many heroes [[ThouShaltNotKill refrain from killing]], but ''Manga/RurouniKenshin'' is very, ''very'' serious about the topic -- to the point of preventing ''other'' people from killing if at all possible. It's {{justified|Trope}} by the fact that it's pretty much all that prevents him from regressing back to his "Hitokiri Battousai" persona: A emotionless killer who is utterly remorseless about any and all lives that he takes. He took the vow after [[HeelRealization realizing just how far]] [[MyGodWhatHaveIDone he had fallen]] in his service to the Meiji revolution/government as an anti-Shogunate/pro-Meiji assassin during the Bakumatsu period.
* Also in the ThouShaltNotKill camp, Vash from ''Manga/{{Trigun}}''.
* In ''VideoGame/SuperRobotWarsOriginalGeneration'', Kyosuke promises Lamia that he'll kill her if she loses her mind.
-->If you ever lose your mind, don't worry. I'll destroy you myself.
* ''Manga/{{Naruto}}'''s vow to bring Sasuke back to Konoha. Arguably in the series ''every'' character has one, but Naruto's is the most important plotwise.
** The Five Kage Summit arc {{Deconstructed|Trope}} this, by showing the burden and increasing impossibility that this vow had entailed:
*** After Sakura delivered her [[NeverLiveItDown infamous]] [[FalseConfession fake love confession]] to Naruto to [[BreakHisHeartToSaveHim relieve him of the promise]], not only does [[WhatTheHellHero Naruto call her out for lying]] and then [[ShipSinking reject her outright]] by telling her that he '''hates''' people who lie to themselves, he also tells her that ThePromise was no longer the reason why he wants to bring Sasuke back; he has [[TrueCompanions his own reasons]] now.
*** Naruto then added an addendum: he'll bring Sasuke back or settle for [[TheOnlyOneAllowedToDefeatYou mutual death]] to eliminate the threat Sasuke has become.
** Naruto made one over [[BloodOath Hinata's blood]], to defeat Neji in the Chunin Exams finals and avenge [[NoHoldsBarredBeatdown her brutal defeat at the preliminaries]]. He succeeded.
*** In ''Anime/TheLastNarutoTheMovie'', he made another one to Hinata, only this time it was [[spoiler:to save her from [[BigBad Toneri]] and properly return her love for him]]. He also succeeded.
* Edward Elric from ''Manga/FullmetalAlchemist'' made a vow to his brother to restore his body without resorting to the Philosopher's Stone, which drives him for most of the story. He also [[ThouShallNotKill refuses to kill people]] but unfortunately sometimes his two vows clash.
** Also, and similar to the ''VideoGame/SuperRobotWars'' example, Riza Hawkeye has promised Roy Mustang that if he ever deviates from the righteous path, she will shoot him rather than let him go against his ideals. In an odd twist, this was ''his'' idea.
* In ''Anime/MobileSuitGundamUnicorn'', Banagher gave his word to Audrey that he would protect her, and he's sticking to it, no matter what fights he gets plunged into and whether Audrey would like this or not.
* Shinn from ''Anime/MobileSuitGundamSEEDDestiny'' [[DeclarationOfProtection vows to protect]] Stella, even if it means [[spoiler:handing her over to the Earth Alliance for medical treatment (and handing them a powerful combat asset), not attacking her while she wipes Berlin off the map, or attacking the Freedom in order to stop it from doing so.]]
* Balsa from ''Anime/MoribitoGuardianOfTheSpirit'' has vowed to save one life for everyone who died to protect her. When her childhood friend and healer [[WhatTheHellHero called her out]] on how many lives she was taking in her efforts to accomplish that goal, she further swore [[ThouShaltNotKill never to kill]].
* In ''Anime/EurekaSeven'', Renton make a personal vow that he will protect his beloved Eureka. He nearly broke his vow when he [[spoiler: ran away from Gekkostate]] in episode 21, but this vow eventually motivates him to go back.
* In ''Anime/YuGiOhGX'', Aster Phoenix had his fortune told that he would one day save his ChildhoodFriend Sartorius from evil, and Aster promised him he would. During the actual conflict years later, Sartorius is under DemonicPossession by the [[ExactlyWhatItSaysOnTheTin Light of Destruction]] and the real Sartorius appears in Aster's mind apologizing that he involved Aster in his attempt to save himself, but Aster admits he really does want to save his friend from the Light because Sartorius has helped him so much as a friend.
* Dr. Kenzo Tenma in ''Manga/{{Monster}}'' is bound and resolved to do two things: save every life he possibly can (as a wanted fugitive, he more than once has to hold people at gunpoint in order to get them the emergency care they need), and kill Johan. The inconsistency between these two vows is not missed, to put it mildly.
* Even though they were the [[HeroAntagonist antagonists]] at the time, the [[AntiVillain Wolkenritter]] swore during ''Anime/MagicalGirlLyricalNanohaAs'' that [[ThouShaltNotKill they wouldn't kill anyone]] during their quest to fill the [[ArtifactOfDoom Book of Darkness]] since it would taint [[MoralityPet Hayate's]] name with blood.

* SpiderMan has the infamous quote, "With great power comes great responsibility."
** After J. Jonah Jameson's wife is murdered by Alistair Smythe thanks to his Spider-Sense burning out, Spidey adds a new one "As long as I live, no-one else dies."
* The ''Comicbook/AstroCity'' story "Old Times" features Supersonic, a FlyingBrick who pledged to always use an original method against each of his opponents. [[spoiler:When he's called out of retirement to stop a rampaging robot, he feels shamed because his impending senility has reduced him to simply hitting it until it stops.]]

[[folder:Films -- Live-Action]]
* In ''Film/ThePrincessBride'', Inigo Montoya devotes his entire life to finding the six-fingered man who killed his father.
** Similarly, Inigo insists on a fair fight with his opponents, to the point of helping the Man in Black up the cliff and waiting for him to be rested before beginning their duel.
-->'''Inigo:''' I promise I will not kill you until you reach the top. \\
'''Man in Black:''' That's ''very'' comforting, but I'm afraid you'll just have to wait. \\
'''Inigo Montoya:''' Isn't there any way you trust me? \\
'''Man in Black:''' Nothing comes to mind. \\
'''Inigo Montoya:''' I swear on the soul of my father, Domingo Montoya, you will reach the top alive. \\
'''Man in Black:''' ... throw me the rope.
* In ''Film/GIJoeTheRiseOfCobra'', Snake-Eyes takes a vow of silence [[spoiler:after the death of the Hard Master.]]
* There's a RunningGag in ''Film/GalaxyQuest'' where Sir Alexander Dane winces every time he hears or says his CatchPhrase. It becomes a Heroic Vow after [[spoiler:the death of his protege Quellek.]]
* The Contract in ''Film/TheManWhoWouldBeKing'' is one of these.
* Vlad's in ''Film/DraculaUntold'', when someone mentions they couldn't win the fight against the Ottoman Empire.
-->'''Vlad III Dracula''': I'll find a way.

* Two major ones from ''Literature/{{Animorphs}}''. Firstly, the kids will never morph a sentient species without the individual's express permission. The other vow is a little more vague: The kids "fight Yeerks, but won't become them". This essentially means the kids agree to not use the same underhanded tactics Yeerks use (cold-blooded murder, ganging up on a single enemy, etc.) [[spoiler:They end up breaking both of these vows.]]
* ''Literature/TheChroniclesOfNarnia'': In "Literature/TheVoyageOfTheDawnTreader", Reepicheep pledges to find Aslan's country. Caspian also vowed at his coronation to search for the seven missing lords.
* Creator/TerryPratchett's ''Literature/{{Discworld}}'':
** In ''Discworld/{{Thud}}'', Sam Vimes will stop whatever he's doing and go home to read "Where's My Cow?" to his son at 6 o'-clock... even if he's halfway across town or buried underground at the time.
-->Every day. Read to Young Sam. No excuses. He'd promised himself that. ''No excuses.'' No excuses at all. Once you had a good excuse, you opened the door to bad excuses.
** The novels suggest that this is the only reason Granny Weatherwax doesn't become a stereotypical WickedWitch.
* ''Literature/TheDivineComedy'': The reason {{The|Oathbreaker}}s have the lowest place in Heaven is that freedom is the greatest treasure a person can give to God, making vows of celibacy and service matters of incredible heroism and seriousness.
-->''"For when a pact is drawn between a man\\
and God, then through free will, a man gives up\\
what I have called his treasure, his free will."''
* ''Literature/TheDresdenFiles'' have the Knights of the Cross. They are three paladins in the modern world wielding a Sword that carries in its hilt a Nail that pierced Jesus Christ. Their Swords are called ''Fidelacchius'' aka the Sword of Faith, ''Esperacchius'' aka the Sword of Hope, and ''Amoracchius'' aka the Sword of Love. While they each get missions and intuitions from the Lord-On-High or His administration, non-Christians may be Knights. Their vow isn't to the doctrine of Christianity, but rather an accepting that people need help and they will help them, even at the risk of their own life to help people. They will not harm the innocent. They will follow the ideals that particular Sword invokes.[[note]] A half-human vampire woman who was once burned by touching the Sword of Faith is later able to wield the Sword of Love when she is protecting the life of her daughter[[/note]] And most importantly, the first mission of any Knight is to ''save and redeem'' the lives of those who are possessed by {{Fallen Angel}}s, not to strike them down. It isn't their place to judge. Failing these vows means risking the Power of the Sword itself as acting against the nature of the Sword could rob the power from the Sword. That said, it is possible another could take up the Sword and reawaken the dormant power.
* Sparhawk of Creator/DavidEddings' ''Literature/TheElenium'', who maintains an ironclad sense of personal honor and dignity despite his own world-weary cynicism and the criminals and evils he has to deal with.
* In the ''Literature/ElephantAndPiggie'' book "Can I Play Too?", Piggie vows to find a way so Snake can play catch with them, even though he lacks any appendages to do so.
* Arguably, Aziraphale in ''Literature/GoodOmens'' has one in regards to profanity. [[spoiler: [[PrecisionFStrike He breaks it]].]]
-->"Oh dear," muttered Aziraphale, not swearing with the practiced ease of one who has spent six thousand years not swearing, and who wasn't going to start now.
* Surprisingly defied in ''Literature/TheLordOfTheRings'' when the Fellowship is formed. Gimli wants the Fellowship to swear an oath to protect Frodo and get the Ring to Mount Doom, but Elrond refuses to allow it. "No oath, no bond is laid on you to go further than you will." Turns out to be a good thing in the end, since it allows most of the Fellowship to part from Frodo (due to circumstance and necessity) without becoming TheOathBreaker.
* These are a major element in C.J. Cherryh's ''Literature/MorgaineCycle''. They form a big part of Vanye's characterization due to his [[InTheBlood Nhi]] obsession with [[HonorBeforeReason honor]], and when he does something stupid to keep his honor he's generally [[GenreSavvy well aware]] of the stupidity of what he's doing. Oaths, their making, their consequences and the attendant difficulties, anguish and so on make for some major drama.
* In ''Literature/{{Pact}}'', Blake Thorburn swears to Evan Matthieu, the [[UndeadChild ghost of a murdered child]], that he will kill monsters like the one that killed Evan. Blake keeps this oath even after being made an {{Unperson}} by a demon and [[HeWhoFightsMonsters losing his humanity]], though he later redefines his definition of "monster" to include monstrous ''people''.
* In ''Literature/{{Pyrates}}'', George van Gelder and his friends pledge to protect each other no matter what.
* In ''Literature/TheStormlightArchive'', the Knights Radiant have oaths (called Ideals) that represent their bonds to their [[BondCreature spren]], and grant them their powers.
** The first is the same for every Order:
--->[[MartialPacifist Life before death]], [[ComesGreatResponsibility strength before weakness]], [[HonorBeforeReason journey before destination]].
** The Second Ideal of the Windrunners:
--->[[WeHelpTheHelpless I will protect those who cannot protect themselves]].
** The Third Ideal of the Windrunners:
--->[[SaveTheVillain I will protect even those I hate]] [[NeutralGood so long as it is right.]]
** The Second Ideal of the Skybreakers:
--->I will put the law before all else.
** The Second Ideal of the Edgedancers:
--->I will remember those who have been forgotten.
** The Third Ideal of the Edgedancers:
--->I will listen to those who have been ignored.
** Lightweavers make no oaths beyond the first, and only need to speak truths (especially about themselves) to advance.
** The Second Ideal of the Bondsmiths:
--->I will unite instead of divide. I will bring men together.
* Gawyn Trakand from ''Literature/TheWheelOfTime'' swears an oath to protect his sister to the death, even when she makes his childhood a living hell with her antics, she runs off in the middle of training twice, leaving him behind. [[FromBadToWorse It gets worse,]] yet he never waivers.
%%* Morley's Code of Ethical Behavior from ''Literature/BurntEmpire''.
%%-->Rule One: Don't kill anyone, ever.
%%-->Rule Two: Never blackmail, especially not for anything disgusting.
%%-->Rule Three: Never steal, ever.
%%-->Rule Four: [[ThereIsNoRuleSix There is no Rule Four]].
%%-->Rule Five: Don't insult anyone who doesn't deserve it.

[[folder: Live Action TV]]
* ''Franchise/StarTrek'''s [[AlienNonInterferenceClause Prime Directive]]: Every Starship captain swears a solemn oath that he will risk his ship and crew, rather than interfere with a planet's normal development.
** It may seem to be violated so often it is hardly a vow at all, but many of the cases are actually a case of LoopholeAbuse, especially [[Series/StarTrekTheOriginalSeries early on]]: the Prime Directive forbids interfering with a planet's ''normal'' or ''healthy'' development, depending on the quote in question. A captain may argue that failing to develop at all is not normal or healthy development, especially if it is not by the free choice of the members of the culture in question, and Starfleet itself originally ''mandated'' discreet interference in the most severe case of ceasing to develop, namely ceasing to exist. The Prime Directive is also superseded by a Starfleet vessel's requirement under interstellar law to respond to distress calls and render any possible aid, which was a plot point in one episode of TNG.
** The principle is generally expressed as a right of self-determination for any society. Even if this means that society making choices which harm or even destroy itself (like oppressive government or civil war). It is also taken much more seriously in the case of civilizations which have not yet developed interstellar travel, that's where the "normal development" part really comes into play; these civilizations have to find their own way to the stars while figuring out how best to run their society (or not). They are treated some-what like under-age minors, simply off-limits even if you might have the best of intentions. In-universe, opinions differ on whether "normal development" includes acts of nature (like the local sun going supernova or a naturally occurring disease which threatens to wipe out a sentient species who possess inadequate medical technology).
** More than one writer in the ExpandedUniverse has portrayed the Prime Directive as extremely problematic in-universe, a knee-jerk reaction to a couple of incidents where GivingRadioToTheRomans went catastrophically wrong that was too vaguely-worded and poorly thought out, but which nobody can figure out how to revise for the better.
* In ''Series/{{CSINY}}'', Mac Taylor will categorically not allow evidence fabrication or tampering within his lab.
* Derek Reese from ''Series/TerminatorTheSarahConnorChronicles''. He will stop at absolutely nothing in order to fight the coming cybernetic invasion, simply because no matter how hopeless it gets, it's not just the right thing to do... it's the ''only'' thing to do.
* ''Series/DoctorWho'':
** The Doctor holds such a vow. It is that vow which defines what it means to be the Doctor.
---> '''The Doctor''': Never cruel or cowardly. Never give up, never give in.
** The so called "War Doctor", or Not-Doctor, iteration is thus his deepest shame. Because he feels like in that incarnation he ''did'' give up on finding a way to TakeAThirdOption, choosing mass genocide (of his own people) in order to save the universe. [[spoiler: Except it turns out he didn't, but had to suppress his own memory of interacting with his future selves when they saved Gallifrey instead]]
** He also follows ThouShaltNotKill. ''That'' one he's a bit more flexible about when push comes to shove, but he's never happy to violate it, and only ever as an absolute ''last'' resort (usually involving making a HeroicSacrifice himself at the same time)
---> '''Madame Kovarian:''' The anger of a good man is not a problem. Good men have too many rules.\\
'''The Eleventh Doctor:''' ''([[TranquilFury calmly]])'' Good men don't ''need'' rules. Today is not the day to find out why I have ''so many''.
** The tenth Doctor also feels that he needs to give the villains a chance to peacefully surrender, even when it's painfully clear that they won't, and it may cost him his life. In one case, a {{Heel Face Turn}}ed genius has to perform a HeroicSacrifice to keep him from doing the same.
* In ''Series/WolfHall'' this is more of an Anti-Heroic vow, given who speaks it, however. When George Cavendish tearfully relates the story of Cardinal Wolsey's sudden arrest for high treason and his fatal illness, which he implies was [[DeathByDespair brought on by the shock and hurt]], he prays God to take revenge on the Boleyns and the other men who brought Wolsey down. Thomas Cromwell's reply sets the stage for the rest of the series.
--> "No need to trouble God, George. I'll take it in hand."

* The Music/{{KISS}} song "The Oath" from ''Music/MusicFromTheElder''.
-->"Your glory, I swear I ride for thee;
-->Your power, I trust it rides with me;
-->Your servant, I am and ever shall I be."

[[folder:Tabletop Games]]
* The ''TabletopGame/DungeonsAndDragons'' {{Splat}} book, ''The Book of Exalted Deeds'', has various vow Feats that carry advantages and disadvantages. The Vow of Poverty for instance disallows you from owning equipment, but gives you roughly 80% of your estimated wealth in bonuses).
** In the Fifth Edition of Dungeons and Dragons, all {{Paladin}}s must swear an oath when they reach third level. The oath of a paladin not only determines what abilities they will get as they level up, but also sets a code of conduct which they must always uphold. For example, Paladins who swear the Oath of Devotion [[KnightInShiningArmor strive to uphold the ideals of honor and chivalry]]. Those who swear the Oath of the Ancients promise to protect all the beautiful, life-giving things in the world. Paladins who swear the Oath of Vengeance devote their life to [[KnightTemplar hunting down and punishing evildoers, no matter the cost]]. If a Paladin willfully breaks their oath, they either lose their paladin abilities until they repent, are forced to switch character classes, or become an [[TheOathBreaker Oathbreaker]].
* In ''TabletopGame/{{Exalted}}'', the Charm Righteous Lion Defense causes a magically enforced version of this: one of the character's Intimacies becomes utterly inviolate, and nothing, not even MindControl, can persuade him to act against it.
* In ''TabletopGame/{{Warhammer 40000}}'', the [[KnightTemplar Black Templars]] chapter of {{space marine}}s, an army of particularly pious {{warrior monk}}s, may choose a vow that affects how they fight a battle. One, for example, gives all models a weak saving throw against ranged attacks that would normally ignore their PowerArmor, but keeps them from taking cover, while another forces units to charge at the nearest enemy but grant them significant combat bonuses when doing so.
* The titular Oath of [[TabletopGame/MagicTheGathering Oath Of The Gatewatch]]. Each of the members has their own personal version.
-->'''Gideon Jura:''' "I have seen civilization fall. When [[EldritchAbomination the Eldrazi]] destroyed Sea Gate, they threatened all I believe. The people of Zendikar—my whole army—were nothing more than stinging flies in their path. Never again. Not just the Eldrazi, and not just Zendikar. Never again, not on any world.

-->'''Nissa Revane:''' "I have seen a world laid waste. As the Eldrazi sweep over Zendikar, the land is reduced to dust and ash. Left unchecked, they will consume it and everything on it.

-->'''Jace Beleren:''' "I have seen a greater danger than I could have imagined. The Eldrazi don't threaten just Zendikar. If we leave here, if we leave them alone, they could consume plane after plane until even Ravnica is laid waste.

[[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=407570 For the sake of the Multiverse, I will keep watch.]]"
-->'''Chandra Nalaar:''' "Every world has its tyrants, following their own desires with no concern for the people they step on. They're no different from the Eldrazi. So I'll say it: never again.

-->'''Liliana Vess:''' "I see that together we're more powerful than we are alone. If that means I can do what needs to be done without relying on the Chain Veil, then [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=414395 I'll keep watch. Happy now?]]"
-->'''Ajani Goldmane:''' "[[AmbitionIsEvil I have seen tyrants whose ambitions knew no limits]]. [[RageAgainstTheHeavens Creatures who styled themselves gods]], or [[AssimilationPlot praetors]], or [[BigBrotherIsWatching consuls]], but thought only of their own desires, not of those they ruled.

He instead encourages her to have faith in him and the other heroes in the form of a vow that he will never give up. Cosmos is so moved by his vow that she in turn makes one of her own, to not lose faith in him and the others.
--> '''Warrior of Light''': I have made a vow to obtain the crystal and save the world. That vow gives me strength.
--> '''Cosmos''': I understand your determination. Then I shall also make a vow...to believe in all of you until the end.
* Shirou in ''VisualNovel/FateStayNight'' has an interesting personal vow. Apart from the one about saving everyone, that is. This one is about how he can accept losing to an enemy, but he ''refuses'' to let his own weakness or body get in the way. Basically, he refuses to give up until [[{{Determinator}} you kill him outright where he stands.]] [[spoiler:And in one HF ending, he appears to surpass even ''that'' to save Sakura.]]

* [[VegetarianVampire Valvatorez]] from ''VideoGame/{{Disgaea 4| A Promise Unforgotten}}'' has made a vow to never drink human blood until he can show a certain woman true fear. He does not care that the woman in question is long dead, the vow has depleted him of all his former power and standing, and that everybody except for him agrees that the vow is utterly unnecessary - he made a promise and he's going to keep it. [[spoiler:He eventually does show Artina ([[AscendToAHigherPlaneOfExistence now an angel]]) true fear in one of the epilogues: the fear of losing him.]]
* Luke fon Fabre in ''VideoGame/TalesOfTheAbyss'' makes one of these after the [[spoiler: destruction of Akzeriuth,]] complete with ImportantHaircut. He essentially vows to accept responsibility for what he has done, begin making decisions for himself, and [[TheAtoner atone for his crime.]] Considering he's spent the last portion of the game either completely [[NeverMyFault denying his guilt]] or in combo HeroicBSOD / HeroicRROD, this is [[CharacterDevelopment pretty damn awesome.]]

As a result of a natural 100 out of a d100, it's....very impressive for someone six years old, to say the least.
--> “I, Kytheus Rhavenfell, Swear upon Kythuna, all the gods, my blood, my father’s blood, and all our ancestor’s blood to safeguard Rhavenfell and its people against all that would wish it harm!
