Counterspelling

Once this spell is used as a reaction against an enemy spellcaster, you can change a single letter in the spell that they cast to change the effect of the spell, such as changing Wish to Fish to make it summon a singular fish instead of granting a wish.

PLEASE NOTE THAT THIS SPELL SHOULD ONLY BE OBTAINED THROUGH THE RING OF THE GRAMMARIAN, AND SHOULD NOT BE ADDED AS A NORMAL CANTRIP WITHOUT THE RING. THANK YOU!
