Benefits
Upon casting a spell with an elemental feature, you can change the elemental type between Earth, Fire, Air, Water, and Poison. These changes can cause the spell to be resisted or enhanced by resistances, immunities, or vulnerabilities. When changing the elemental type, the new element will have the properties as if it's naturally occuring.
