Obedient avalanche

Obedient avalanche, also known by many as Zajimarn's avalanche, was a conjuration spell of the creation subschool that called down an avalanche to bury one's foes.

Effect
The spell opened a rift in midair, from which poured an avalanche of snow that engulfed everyone and everything beneath it in area up to 80 ft (24.3 m) wide. The avalanche crushed and froze those directly beneath it, and could even bury them in heavy snow. Further away, the impact was less, but the spreading snow shoved all aside.

The obedient avalanche also damaged buildings and other structures, uprooted small trees and lesser plants, and turned the ground into a trail of rubble in the snow's path. It also put out all fires, whether they were natural or magical in nature.

Users
The obedient avalanche was formerly unique to clerics with the Cold domain, but could later be learned by sorcerers and wizards.
