Dragonshape

You feel a fire burning deep within you. Crimson scales quickly grow over your body, a pair of great wings sprout from your shoulders, and the scent of sulfur fill the air as you transform into a dragon.

You take the form of a Large young red dragon. You assume the hit points of its new form, and when it reverts to its normal form, it returns to the number of hit points it had before it transformed. If it reverts as a result of dropping to 0 hit points, any excess damage carries over to its normal form. As long as the excess damage doesn't reduce the creature's normal form to 0 hit points, it isn't knocked unconscious.

The target's gear melds into the new form. The target can't activate, wield, or otherwise benefit from any of its equipment.
