You attempt to transmute a spell’s element type. If a creature casts a spell that does elemental damage you can change the typing to either an element the target is resistant to or to change the element of your Allie’s spells to something the target is weaker against

If the creature is casting a spell of 3rd level or lower, its spell can be changed If it is casting a spell of 4th level or higher, make an ability check using your spellcasting ability. The DC equals 10 + the spell's level. On a success, the creature's spell typing can be changed.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the transmuted spell has no effect if its level is less than or equal to the level of the spell slot you used.
