Become fire

You snap your fingers and you become fire, your entire body consists of white flame, anyone who looks at you must roll a con saving throw or is blinded for one round, peaceful or hostile. To roll a hit, you would roll the same as your punch, if you touch someone, on contact, they take 13d12 fire damage +15, you may manipulate your body to do things like make your arm an axe or a sword, to be hit during this form, the enemy must roll a hit higher than your DEX+your CON, otherwise, the attack passes right through you.
