The spell Oomph (バイキルト Baikiruto, originally localized in English as Bikill, later localized as TwinHits) is a recurring spell in the Dragon Quest series.
For most of the series games, Oomph is used in combat to temporarily double the attack power of a character.
The spell was introduced to Americans as the spell Bikill in Dragon Warrior III. When Dragon Warrior Monsters was released, the spell was localized by Eidos as TwinHits. Enix America kept the localization of the spell name as TwinHits as it released Dragon Warrior VII and remade Dragon Quest III for Game Boy Color. From Dragon Quest VIII on, the spell has been localized by Square Enix as Oomph.
TwinHits is learned by monsters beginning at level 17 if the monster has at least 72 MP and 66 Intelligence. It is learned naturally by AmberWeed, ArmorPede, BeanMan, ChopClown, CurseLamp, Pixy, and StubBird. Additionally, the Diago summoned by DiagoCall can use TwinHits.
