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 succesful save. The targets 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 unconscious or dead.
