Portable Eye
Portable Eye's always come in pairs. Their construction varies, but most commonly they are made from a clear crystal of high quality. As an action, while looking through one of the pair, you can see through the other for up to one hour, as long as you are on the same plane of existence. During this time, you are blind with regard to your own senses. Once per day you may cast a spell through the eye that does not have a range of touch or require an attack roll. Once a spell has been cast through the eye the pair may not be a used until they recharge at dawn. To attune to this item the user must have the pair.
