Watching

In an elaborate ritual, you first place one of the two beads used as material components into the amulet and then place the other into the skull of a target creature, which must be unconscious or willingly within range the entire time. After the ritual is completed, the wearer of the amulet, provided he and the target are on the same plane of existence, can use an action to see and hear everything the target sees and hears until his concentration ends (as if he were concentrating on a spell), he and the target are on different planes of existence, or the spell ends. Meanwhile, he is blind and deaf to his own surroundings. He can also communicate telepathically with the target. By using an action, he can also explode the bead in the target's head, dealing 24d10 blast damage to the target. After that, the spell ends immediately.
