Wyrmsbane (竜特効 Ryū tokkō lit. Dragon Buster in the Japanese version, Fléau des dragons in the French version, Affliggiwyrm in the Italian version, Matawyrms in the Spanish version) is a Skill in Fire Emblem Awakening. A user equipped with this skill will deal effective damage against Wyvern Riders, Wyvern Lords, and Manaketes. However the bonus damage only applies if the user is in the Manakete class and will not activate if the user is in another class. It is learned by Manaketes at Level 15.
Most usage of this skill during the main storyline will be against Wyvern Riders or Wyvern Lords as no enemy Manaketes exist in the game. However this skill can be used against StreetPass Teams who have Nowi, Nah, Tiki, and a Manakete Morgan on them as well as against Tiki in her SpotPass team and in some DLC chapters.
In other games
A precursor to this skill appears in all games with Fire Emblem: Shadow Dragon and the Blade of Light, Fire Emblem: Mystery of the Emblem, and Fire Emblem: The Binding Blade where the Divinestone/Breath of Fog deals extra damage towards Dragon type units.
