Crystallized Defiance

A protective mist of glass shards surrounds the target, manifesting as a spectral frost that covers you and your gear. The target gains 1d10 temporary hit points for the duration. If a creature hits the target with a melee attack while you have these hit points, the creature takes 1d10 piercing damage as shards of glass explode from the target.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, both the temporary hit points and the cold damage increase by 1d10 for each slot.
