Eldritch Invocation: Prismatic Blast

Your mastery of damaging cantrips has improved beyond the limitations of casting a single cantrip in a turn. When you make a spell attack roll for your Eldritch Blast you can instead choose to substitute for another ranged spell attack cantrip you know. This cantrip is cast at its lowest level and still counts as Eldritch Blast for the purposes of gaining benefits from other Invocations.
