Eyepatch of the Allfather

The Eyepatch of the Allfather was created for Odin during the Subjugation of the Nine Realms. Although then just an enchanted object, it became a necessity after losing his right eye against the Frost Giants.

Passive Abilities
Power Immune: The artifact is immune to all effects and powers not cast by the wielder. This doesn't extend immunity to the wielder. It cannot be broken, transported (seperately from the wielder), or altered by an opponent.

Active Abilities
Activate Stones: You may activate the power of the Infinity Stone held within.

Spells: You may cast Teleport and True Sight at will as an action.
