Wondrous Item, Rare (Requires Attunement)
This robe is adorned with eyelike patterns. While you wear the robe, you gain the following benefits:
All-Around Vision. The robe gives you Advantage on Wisdom (Perception) checks that rely on sight.
Special Senses. You have Darkvision and Truesight, both with a range of 120 feet.
Drawbacks. A Light spell cast on the robe or a Daylight spell cast within 5 feet of the robe gives you the Blinded condition for 1 minute. At the end of each of your turns, you make a Constitution saving throw (DC 11 for Light or DC 15 for Daylight), ending the condition on yourself on a success.
