Dazzling Nebula

A beautiful display of colorful gas clouds and sparkling lights springs into existence in a 20-foot cube within range.  The illusion sheds bright light in a 30-foot radius from the edge of the cube and dim light for an additional 30 feet.  The illusion also spreads around corners, and the area within the 20-foot cube is heavily obscured.  Each creature outside of the cube but within 10 feet of it must make a Wisdom saving throw, excluding yourself.  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 n action to shake the creature out of its stupor.
