Feat: Elemental Evolution

The elemental power within you is more mutable and versatile than most. Choose a second damage type for your element. Whenever you Rage, you can choose that type instead of the damage type you would normally gain. The new damage type can be the one you did not choose when you selected the element initially if you had multiple options available for your element, or one of the following types:

air cold

earth poison

fire cold

metal electricity

water acid

wood poison.
