Stored Cataclysm

When a charged object or creature within range would be destroyed, reduced to 0 hit points, or critically hit, release its stored energy. Creatures of your choice within 30 ft. must make a DEX save, taking 66 (12d10) force damage on a failed save, or half as much on a success. The triggering target then survives at 1 hit point if it was a creature.
