Hypnotic Pattern

Create a twisting pattern of colors that weaves
through the air inside a 30-ft cube and vanishes
quickly. Creatures inside who see make a Wis save.
On a fail, the creature becomes charmed for the
duration. While charmed, the creature is incapacitated and has speed 0.
The spell ends for an affected creature if it takes
damage or if someone else uses an action to shake
them out of their stupor.
