Wondrous Item, Very Rare, 33,000 gp
(Requires Attunement)
This robe has 3 charges and regains 1d3 expended charges daily at dawn. While you wear it, you can use an action and expend 1 charge to cause the garment to display a shifting pattern of dazzling hues until the end of your next turn. During this time, the robe sheds bright light in a 30-foot radius and dim light for an additional 30 feet. Creatures that can see you have disadvantage on attack rolls against you. In addition, any creature in the bright light that can see you when the robe’s power is activated must succeed on a DC 15 WIS save or become stunned until the effect ends.
