Ring of Truth

Ring, rare (requires attunement)

This ring of pure silver is usually unadorned or else set with small white stones. You gain advantage on Wisdom (Insight) and Charisma (Persuasion) ability checks to gather information, Wisdom (Perception) checks to spot forgeries, and Wisdom (Perception) checks made to oppose Dexterity (Sleight of Hand) and checks to see through a disguise.

Epic Attunement. You can cast zone of truth at will, but you are constrained to never knowingly lie. You cannot lie up to 24 hours after removing the ring of truth. Creatures stepping within your zone of truth have disadvantage on their saving throws against the spell effect. The DC for this zone of truth is equal to 8 + your Wisdom modifier + your proficiency bonus.
