You unleash the absolute cold that dwells deep within the para-elemental plane of ice. A 50-foot-sphere around you is permeated with a blast of pure frigid energy. Creatures except you in the area must make a Constitution saving throw.

Targets take 18d10 cold damage and are incapacitated and restrained on a failed save, or take half as much damage and instead have their speed reduced by half for 3d4 minutes on a successful save. A creature that fails its save can make a Strength save at the end of each of its turns to end the effects.

If a creature is reduced to 0 hitpoints with this spell, they are petrified in ice instead of becoming unconsious or dead.
