Alter Elements

You shift the energy of a spell to your favor. You change the damage type of a spell, choose one of the following damage types. Cold, Fire, Lightning, or Acid. If the spell deals the same damage type as the chosen type, the spell fizzles.

If the spell of 3rd level or higher, make an check and add your spell modifier. The DC equals 12 + the spells level. If the target is a willing creature, you gain advantage on the check. On a failure the spell fizzles.
