Elemental Shift

Choose one energy type (Acid, Cold, Fire, Lightning, Poison, Thunder; At 11th level additional choices are Force, Necrotic, Psychic and Radiant). You may replace any spell's normal damage with that energy type. This can be taken multiple times to gain multiple elements to choose from. The element type must be declared upon casting the spell and no more than one damage type can be applied at one time.

You may only do this up to twice per long rest. You also must choose between Dexterity, Intelligence, Wisdom, or Charisma to increase by 1.
