5th ring Primordial, Evocation
You eat a chilli pepper, your metabolism increases, and your skin begins to burn to the touch. Make a melee spell attack against a creature within your reach. On a hit, the target takes 6d6 fire damage. Until the spell ends, you can use an action on each of your subsequent turns to make this attack again.
For the duration, your walking speed increases by 15 feet, and you gain 2d6 temporary hit points at the start of each of your turns.
