As a bonus action or part of the bonus action you use to activate rage your skin sheens with an element of your choice. You can use this ability each day equal to your proficiency modifier. While making your skin sheen, choose any 'element' except for physic, while in the same instance of rage you have resistance to the element chosen. As your skin shimmers with magical power any melee attacker also takes 1d6 of the element selected for each successful hit they land on you.
