Alter Letters

You alter the words in the verbal component of an opposing spell. The enemy makes a Wisdom Saving Throw equal to your spell save DC minus the level of spell they cast if the spell is greater than 3rd level. Choose one letter to remove, add, or change from the target spell. The new spell must create a word or phrase, or else the casting fails and the original spell is cast. The effects of the spell are changed based on the new name of the spell. The new effects of the spell are up to the discretion of the DM.
