The Third Eye is a spherical blue crystal carved to appear as an eyeball. When you attune to this item, it rises into air and orbits your head at a distance of 1d3 feet, providing you with its benefits. Thereafter, another creature must use an action to grasp or net the sphere to separate it from you; this requires a successful attack roll against an AC of 24 or a Dexterity (Acrobatics) check of DC 24. 

While attuned to the eye, you gain Truesight at a distance of 30 ft and Darkvision at a distance of 60 ft. You are unable to be surprised, have an advantage on Wisdom (Perception) checks that rely on sight, and have the effects of Detect Magic permanently active. 

Mind Reading. While attuned to The Third Eye, you can use an action to cast Detect Thoughts targeting creatures you can see within 30 ft. This version does not require concentration and instead lasts its entire duration or until dismissed. You can do this up to four times, regaining any expended uses each dawn. 

Hidden. While attuned to this item, you are hidden from Divination magic. You cannot be targeted by such magic or perceived through magical scrying sensors. 

Cursed. After about 1d6 + 2 days after the initial attunement, the user will begin to perceive a strange being off in the distance. Only they are able to see this entity. It appears as a medium humanoid with black charred skin, no head, and pendulum blades instead of arms. It appears visible regardless of obstructions between itself and the observer, including fog, solid walls, terrain formations, or the viewer's eyelids. This is often distracting to you; any time you roll a 5 or lower on the dice for a Wisdom (Perception) check, the creature flashes face-to-face with you, making it impossible to discern whatever you were trying to focus on observing.
