Through extensive research in the field of magic, you are able to effect the formula of the spells you cast. When casting a spell, you may cast this spell as well to alter its effects. You are required to cast this spell using a spell slot of the same level as the one of the spell you are targeting. For example, a Fireball cast at 3rd level would use a Widen Magic cast at 3rd level.
