Gray Buster

Gray Buster (Japanese: 砕氷塵グレイ·バスタ―, Kanji translation: Crush Ice Dust, Romaji: gurei basutā) is a water shamanistic spell with a variety of uses.

The spell lowers temperature in the target area by freezing moisture in the air. The small ice shards glitter like diamond dust, producing a beautiful effect. For obvious reasons, the spell can be quite lethal against those present in the area, but Gray Buster has less aggressive uses as well: A weaker variation of this spell can function as an air conditioner. This is one of the first spells sorcerer pupils learn to use, in order to cool down the classroom.
