Trivia

 * Despite the description stating that it works against debuffed enemies, it means enemies with Status Ailments. Effects such as Burn, Bleed etc. were being called "debuffs" in the earlier versions of the game, which hasn't been changed in the description.
 * Paralysis is written with a typo in the description, as "Paralysisb"
