AntiMute is a curative White Magic spell that restores the power of speech to those who have been muted. It works much like the spells Lamp, Pure, and Soft. AntiMute counters the effects of the spell Mute.
However, this spell is not considered worthwhile since only a couple monsters in the game use Mute or a similar attack, and even then it rarely comes into play. (Trivia: AMUT was nominated as one of the "Most Useless Powerups in Video Game History" at www.seanbaby.com.)
