Ring of Bravado (5e Equipment)
From D&D Wiki
Ring, legendary (requires attunement)
You may only use Ring of Bravado's effect if it is the only thing you are wearing.
Inscribed on the inside of the ring, in Dwarven, is "Don I, and nothing else"
Attuning to Ring of Bravado gives you the following properties:
The Ring of Bravado has 5 charges and regains 1d4 - 1 charges each day at dawn. You may expend 1 charge, as a bonus action on your turn, to cause a blinding light to be expelled from you. Creatures within a 15 foot radius around you must make a DC 13 Constitution saving throw or be blinded until the start of your next turn. Creatures who fail this saving throw by more than 5 are also charmed by you for 1 minute or until attacked.
You may expend all 5 charges simultaneously to cause a large burst of light to erupt from your body. This creates a 30 foot sphere of light around you. All creatures within the sphere must make a DC 17 Dexterity saving throw or take 6d6 radiant damage, and become blinded for 10 minutes. If they pass the check, they take half damage and are not blinded.
Curse. If the Ring of Bravado is the only item you are wearing, it may not be taken off and no other items or clothing may be donned. Donning any other items will make the user incapactitated while the ring transmits messages of nudity to the user's mind. This curse may only be removed from a remove curse spell or similar effect.
