Link Sight

The target and the recipient each eat a whole eye, after which (within a 5 minute window of time) the mage speaks the incantation and targets one of the two creatures who consumed an eye, who becomes the target. The target feels nothing specific, but the other entity, the recipient, can see through the target's eyes, as a second set of eyes.

The spell lasts 2 hours, but if the target enters combat, the stress ends the spell, and the recipient is blinded for the remainder of the time. The recipient can end the spell by taking a minute to focus. During this focus they cannot do anything distracting.
