You create a pattern of lights that pulses with intensity. Creatures are
dazzled while inside the pattern. In addition, a creature must attempt a Will saving throw if it's inside the pattern when you cast it, enters the pattern, ends its turn within the pattern, or uses a Seek or Interact action on the pattern. A creature currently
blinded by the pattern doesn't need to attempt new saving throws.
Success The creature is unaffected.
Failure The creature is blinded by the pattern. If it exits the pattern, it can attempt a new save to recover from the blinded condition at the end of each of its turns, to a maximum duration of 1 minute.
Critical Failure The creature is blinded for 1 minute.
