1st-level Spell: Prismatic Flash

Aspetheurgy (Illusion)

A vivid rainbow of prismatic lights springs out from your hand. Each creature in a 15-foot cone must make a Constitution saving throw. On a failure, a creature is blinded until the start of your next turn. On a success, a creature is not blinded but is disoriented by the brilliant flash and cannot make attacks of opportunity until the start of your next turn.
Creatures that are already blinded or cannot see you aren’t affected as they do not see the burst.

• At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, the size of the cone expands by 5 additional feet.
