Elemental Kinetic

Your knowledge of the Fire element has advanced to where you can transform incoming damage to fire damage and unleash it on your attacker.  This affect lasts 1 minute (10 rounds). On the first round you deal 7d10 fire damage which is unavoidable, and all following rounds for every 3 points of damage you receive you deal 1 point of fire (ex 12 piercing becomes 4 fire). On each following round a spell save is made to avoid the additional damage, where a save avoids and fail takes the damage. All fire damage dealt through this spell does not cause the condition burning, but if already under the condition add 1d10 to any damage taken.
