An ethereal chain shoots forth from your chest at a creature you can see within range. The target must make a Charisma saving throw. On a failure, the spectral chain attaches to the target’s body, linking you both together. The chain can stretch to any distance and pass through objects, and you and the target can move away from each other beyond the casting range of the spell without ending the spell. While you are connected in this way, you and the target know each other’s location, even if you can’t see or hear one another. When you take damage, the target takes the same type of damage equal to the amount of damage you take. If damage reduces you to 0 hit points, the target takes the full amount of damage that you would have taken beyond 0 hit points. If you regain hit points while under the effect of this spell, the target gains a number of temporary hit points equal to the number of hit points you regained. Each time a target takes damage from this spell, the target can repeat the saving throw, ending the spell on a success. If you or the target moves to a different plane of existence, the spell ends.
