Orb of Enthralling Patterns

Wondrous item, uncommon (requires attunement)

This plain, glass orb shimmers with iridescence. While holding this orb, you can use an action to speak its command word, which causes it to levitate and emit multicolored light. Each creature other than you within 10 feet of the orb must succeed on a DC 13 Wisdom saving throw or look at only the orb for 1 minute. For the duration, a creature looking at the orb has disadvantage on Wisdom (Perception) checks to perceive anything that is not the orb. Creatures that failed the saving throw have no memory of what happened while they were looking at the orb. Once used, the orb can’t be used again until the next dawn.
