Scintillating Spell

Your spells become a radiant display of light and color. If your next action is to Cast a Spell that doesn't have the darkness trait, has no duration, and requires creatures to attempt a Reflex save, the spell explodes in a spray of scintillating lights, in addition to its other effects. Each creature that failed its Reflex save against the spell is Dazzled for 1 round, and those who critically failed are instead Blinded for 1 round.
