Arc Brass

Arc Brass (Japanese 地霊咆雷陣アーク・ブラス, Kanji translation: Earth Spirits Roar Lightning Ranks, Romaji: āku burasu) is an offensive spell. Its effects suggest that it is an air shamanistic spell, but Encyclopedia Slayers lists it as an earth spell instead, probably based on its kanji representation.

The spell causes lightning to rain down on an area as large as a few city blocks. It is almost impossible to dodge it, but the affected targets do not sustain serious damage; they are usually paralyzed or at worst suffer some kind of a minor mental disorder.
