->''An extra +10 against anything that starts with the letter J. Don't ask why. Don't ask what Vorpal means, either.''
-->-- '''Vorpal Sword''', ''TabletopGame/{{Munchkin}}''

A weapon which gets extra bonuses (possibly including AntiArmor or OneHitKill) against a specific enemy type, without resorting to DepletedPhlebotinumShells (e.g. silver vs. werewolves) or ElementalRockPaperScissors (e.g. using fire against an ice monster). Subtrope of SituationalSword.

There may be some overlap with AchillesHeel; in such cases, consider the weapon's effectiveness against things that ''aren't'' the NighInvulnerable critter.

Unique-named weapons with this kind of property often come with ExactlyWhatItSaysOnTheTin naming.

Compare TheHunter, who is a ''person'' dedicated to slaying a specific enemy type.

!!Examples

[[foldercontrol]]

[[folder:Anime & Manga]]
* ''Roleplay/RecordOfLodossWar'' took this to an extreme, with a set of magical halberds enchanted to slay one specific dragon. [[spoiler:These were effective despite the heroes having to jump off a cliff to hit the dragon's head.]]
* One story arc in ''LightNovel/ACertainMagicalIndex'' revolves around a weapon called the Stab Sword, which is able to kill immensely powerful magic users.
* Technically the Zanpakuto swords from ''Manga/{{Bleach}}'' are used to release dead souls and cut down Hollows. This doesn't make them any better or worse at actually fighting Hollows specifically.
* ''Anime/DigimonAdventure'': Wargreymon's spiked gauntlets are called "Dramon Destroyers"; they give him a particular advantage against [=MetalSeadramon and Machinedramon=].
* The Dragonslayer from ''Manga/{{Berserk}}'' didn't start out as one of these[[note]]While it has its name from a king commissioning a weapon capable of killing a dragon, its forger had never ''seen'' a dragon or even known if they existed, so nothing makes it specialized in actual dragon slaying.[[/note]], but after years of Guts using it against demons, it eventually gains the ability to kill them more effectively. It can even [[spoiler:wound the Godhand themselves]].
[[/folder]]

[[folder:Card Games]]
* Inverted in ''TabletopGame/{{Munchkin}}'' by the "sword of slaying everything except squid". It gives a substantial bonus but against squid (there are two in the decks so far -- karate squid and Squidzilla) the fight is automatically lost.
[[/folder]]

[[folder:Gamebooks]]
* ''Literature/LoneWolf''
** The Sommerswerd, devastating against undead, and deadly even for the Darklords. [[spoiler:It is stated later it could be lethal even against [[BigBad Naar]].]] To be honest, it's quite good at killing ''anything'' anyway.
** The various evil weapons favored by the Darklords have one thing in common: they give combat bonus against ''other Darklords'', and are among the very few things able to kill them permanently. [[ChronicBackstabbingDisorder Those guys truly had their priorities in order.]]
** The jewelled mace from book 5 gives a bonus against illusory creatures.
** The enchanted bullwhip from book 10 can hit (and gives a bonus against) specters.
** The Dessi Stone is a magic gem that, when merged into the hilt of any ordinary weapon, can turn it into an undead slayer.
** Several of the weapons forged by Lone Wolf with Kai Weaponcraft in the New Order series have a CS bonus when used against specific creatures, like reptiles, undead, stone beings, magic-users, flying monsters or fire-breathers, respectively.
[[/folder]]

[[folder:Literature]]
* The eponymous weapons of the ''Literature/{{Dragonlance}}'' setting were exceptionally effective against dragons.
* In the ''GotrekAndFelix'' novels, Felix's SituationalSword is especially effective against dragons.
* In ''Lord Demon'', many of the demons have weapons that are attuned to kill them specifically. Kai Wren shows up to one duel wielding the sword made to kill his opponent, and the wounds he sustains don't heal properly. Kai Wren also has an OhCrap moment when he realizes just who has the weapon made to kill ''him''.
* ''Literature/ThePrismPentad'': The Scourge of Rkard is amazingly effective against [[BigBad the Dragon]] and the various [[SorcerousOverlord Sorcerer Kings]].
* In Nick Perumov's ''Keeper of the Swords'' series, Fess the necromancer occasionally uses a dwarven falchion of undead slaying to pacify those unruly zombies.
[[/folder]]

[[folder:Live-Action TV]]
* Three examples in ''Series/StargateSG1''.
** The first is the energy weapon for killing [[BigBad Anubis']] [[SuperSoldier Kull warriors]], which is of indeterminate use against anything else but will kill Kull in a couple shots by negating the Ancient phlebotinum that brought them to life in the first place.
** The second is the Replicator disruptor and the anti-Replicator gun later adapted from it, weapons built using Ancient knowledge that disrupts the ability of individual Replicator blocks to communicate with each other.
** Finally, the weapon Merlin designed to destroy ascended beings, which is finally used to wipe out the Ori in season 10.
[[/folder]]

[[folder:Tabletop Games]]
* ''TabletopGame/DungeonsAndDragons''
** The magic item lists in have a lot of these -- "sword +2, giant slayer", "arrow of slaying", etc.
** Third Edition generalized these with the "bane" effect (+2 to hit and +2d6 damage against specified enemy).
** The Hammer of Thunderbolts, if hurled by a dwarf aware of its power, can OneHitKill giants.
[[/folder]]

[[folder:Video Games]]
* The golem staff in ''VideoGame/WizardsCrown'', which is just a normal staff unless you attack a golem with it, in which case it [[ArmorPiercingAttack ignores armour]] and has its damage rating tripled.
* ''Franchise/FireEmblem''
** A lance called Horseslayer which is [[AntiCavalry highly effective against cavalry]].
** There are also the Axereaver, Swordreaver and Lancereaver weapons, which reverse the [[TacticalRockPaperScissors weapon triangle]] by being effective against the weapon referred to in their name.
** In ''Radiant Dawn'', Micaiah gets the character-exclusive Thani, light magic of HeavilyArmoredMook slaying.
* ''Franchise/FinalFantasy''
** ''VideoGame/FinalFantasyI'' and some of its sequels have various weapons of this kind. They didn't work in the first game, however, due to a bug (which was fixed in the remakes).
** ''VideoGame/FinalFantasyIX'' allowed characters to equip various "killer" abilities (e.g. Demonkiller, Birdkiller) that caused ''whatever'' weapon they had to deal bonus damage.
* ''VideoGame/{{Angband}}'' has a set of Slay X properties (Evil, Orc, Demon, Undead, Troll, Giant, Animal, and Dragon), which can be found in various combinations on ego and artifact weapons.
* ''[[VideoGame/AncientDomainsOfMystery ADOM]]'' followed a similar model to ''Angband''; the possible values of X in this case included ''humanoids'' (which category included some bosses and most elite mooks).
* ''VideoGame/DungeonCrawl'' has weapons of orc slaying, which simply give a damage bonus against orcs.
* Several of the artifact weapons in ''VideoGame/NetHack'' fall into this category e.g. Ogresmasher, Werebane (which happens to ''also'' invoke DepletedPhlebotinumShells, since it's a silver saber), and Orcrist. Additionally Vorpal Blade, which can OneHitKill anything with a head 5% of the time, does so 100% of the time against jabberwocks.
* ''VideoGame/{{Diablo}}'' gives all blunt weapons this effect against undead monsters, and ''Diablo II'' also has weapons with specific anti-undead or anti-demon enchantments.
* Weapons with bonuses against the Darkspawn, undead, and/or demons are pretty commonplace in the ''Franchise/DragonAge'' series, but ''VideoGame/DragonAgeII'' also has a greatsword with a large bonus against [[ProudWarriorRace Qunari]]. Fittingly, [[spoiler: you pick it up shortly before storming a Qunari stronghold.]] In the following act, a Qunari gives you a sword specialized against humans (probably as a stealth comeback).
* ''VideoGame/ValkyrieProfile''
** The series has a whole range of Slayer weapons -- they tend to be {{breakable|Weapons}}, making them TooAwesomeToUse against anything but bosses. The game only rolls to see if a weapon breaks at the start of your enemy's turn, however, so if you finish the battle in one round, it will never make the check, allowing them to last you through the whole game. As the weapons are uniformly a one-hit kill, the only real danger of losing them comes when you're facing more than one such enemy, which happens rarely, and only after you've had the opportunity to pick up multiple weapons of the type.
** In addition to the Slayer weapons, there are also weapons that have a Death effect based on a given element. With these, the weapon will instantly kill anything that has that elemental weakness, regardless of total HP or defenses. This includes the penultimate boss on the way to the GoldenEnding, who can be killed in one round by a sword you picked up around the midpoint of the game.
** ''[[VideoGame/ValkyrieProfileCovenantOfThePlume Covenant of the Plume]]'' doesn't have the OneHitKill weapons, but it still has weapons with bonuses against specific monster types.
* ''VideoGame/AgeOfWonders: Shadow Magic'' has a "[[http://aow2.heavengames.com/aowsm/gameinfo/unitabilities/general.shtml#Dragon%20Slaying Dragon Slaying]]" unit ability, given to Knight and available on weapons for Hero Unit.
* ''VideoGame/RuneScape'' has several examples, including Silverlight (and its upgraded form, Darklight) for slaying demons; Balmung, the Battleaxe of Dagannoth Slaying; the Ivandis Flail, used for killing Vyrewatch vampyres; and the brackish blade and brine sabre, which are super-effective against crabs for some reason.
* ''VideoGame/ShiningForce'' has a variety of specialized weapons that are strong against specific types of enemies -- the Mermanbuster is strong against sea creatures, the Jagged Flash is strong against flying enemies, the Elf Slayer is good against robots, and so on.
* ''VideoGame/CastlevaniaSymphonyOfTheNight'' has the Werebane, which is supposed to do more damage against werebeasts. [[InformedAbility It doesn't.]] Apparently they didn't program it correctly...
* ''VideoGame/TheLegendOfDragoon'' has two ancient weapons forged to defeat Dragons and Dragoons: one of them was the [[LaserBlade Dragon Buster]] sword, capable of piercing the Dragoon armor. Unlike most video game examples, it's your ''enemy'' that wields it, handicapping you during your battles against him.
* In ''VideoGame/LegendOfMana'', weapon upgrades can bestow ''or remove'' this effect.
* ''VideoGame/EverQuest'' has a "Bane" effect which increases damage towards a particular species of monsters.
* ''VideoGame/{{Wizardry}}'' has weapons dealing double damage to specific types. 7-th has weapons against Dragon, Robot, Undead and, due to a silly bug, Fighter; in 8-th against Android, Beast, Demon, Dragon, Plant and Undead.
* ''Crossfire'' adventure game has slaying weapons, and when a deity blesses someone's weapon, it usually acquires the slaying property vs. the kind of creatures this deity doesn't like.
* Most games in the ''VideoGame/DragonQuest'' franchise have an assortment of these, doing higher damage against the designated enemy (e.g. weapons with "metal" at the start of the name usually do extra damage when they hit a MetalSlime, while the dragonsbane does extra damage to dragons).
* In ''VideoGame/{{Drakensang}}'', dwarves have the Wyrmslayer Ax (a small hatchet with a very big blade) and also the Dragonslayer Axe, the Dragon-Crushing hammer, the Dragon-Piercer crossbow and the [[OverlyLongGag Dragon Spear]] (as in a trident made for skewering dragons). Yes, before you ask, dwarves hate dragons, and even have something like seven different words to define the death of a dragon.
* ''VideoGame/KingdomHeartsChainOfMemories'' played this straight and averted it, by giving various cards elements, using fire type against water-type gives an extra attack boost. However using the same element heals them.
* ''VideoGame/FallOut3'' has pulse grenades and pulse mines dedicated to fighting robots. There is also a stick that makes mole rats heads explode.
* ''VideoGame/TheElderScrollsVSkyrim'' has a few here and there:
** Silver swords, dropped by the werewolf-hunting Silver Hands, [[SilverHasMysticPowers do more damage to werewolves and the undead]].
** There's a woodcutting axe that does extra damage to animals (which can then be disenchanted and applied to other weapons); and the artifact axe Wuuthrad [[ScrewYouElves does more damage to Elves]].
** There also exists a weapon that does more damage to Nords in the game's code, but it's sadly DummiedOut.
** The Daedric artefact Dawnbreaker, which not only sets regular foes on fire but does extra damage to undead, the latter of which can trigger an explosive shockwave that either delivers a OneHitKill to any remaining undead or makes them [[AttackAttackRetreatRetreat run for the hills]].
** Dragonbane, a one-handed sword you obtain in Sky Haven Temple, does extra damage against dragons and shock damage against everything else. It's impractical against the latter though, since its charge is low and unlike other shock weapons it doesn't drain magicka.
** ''Dawnguard'' give us a series of weapons than do extra damage against vampires and the bow of a god that does extra damage against undead.
* ''VideoGame/{{Minecraft}}'' has two sword enchantments in this category: "Smite" gives a damage bonus against undead enemies, while "Bane of Arthropods" gives this bonus against spiders and silverfish.
* ''VideoGame/LufiaIIRiseOfTheSinistrals'' has a set of weapons that are extra effective against {{giant spider}}s, another that is the same for lizard (including dragons). Another set, much later, effects only dragons but has a higher base damage than the anti-lizard set.
* ''VideoGame/{{Earthbound}}'' has spray bottles filled with Rust Promoter (which damages robots) and Insecticide (guess).
* A quest in ''TheSimsMedieval'' requires you to make a dragon-slaying sword called Wyrmslayer.

[[folder:Web Comics]]
* ''Webcomic/{{Roommates}}'' makes the [[Literature/TheHobbit Orcrist]] this against [[OurGoblinsAreDifferent Goblins]], and even more against anybody currently holding the Goblin King title.
[[/folder]]

[[folder:Web Original]]
* ''Blog/ThingsMrWelchIsNoLongerAllowedToDoInAnRPG'': Mr. Welch has occasionally been reprimanded for forging weapons of [[FalseFriend party member slaying]].
