Aurora Borealis

You create a swirling wisps of lights that weave through the air inside a 30-foot cube within range. The ephemeral vapors coalesce for a moment before dispersing. Each creature in the area that gazes upon the vapors must make a Wisdom saving throw. On a failed save, the creature becomes charmed for the duration. While charmed by this spell, the creature is incapacitated and has a speed of 0.

The spell ends for an affected creature if it takes any damage or if someone else uses an action to shake the creature out of its stupor.
