Arkwright's Vigilant Tether

You touch a willing creature of your choice. That creature forms an arcane bond with you for the spell’s duration, allowing you to act and perceive from its position.

Whenever you take the Attack action on your turn, you can attack as if you were in the tethered creature’s space. You can also cast spells and make opportunity attacks from that space.

You can communicate telepathically with the connected creature as long as it is on the same plane of existence as you. Additionally, as an action, you can see and hear as if you were in that creature’s space. Until you lose concentration on the spell, or return to your space as an action, you are blind and deaf with regard to your own position.
