Deadly Embrace

You touch a living creature and embrace it while forcing it to make a Constitution saving throw. On a failed save, it's grappled by you and takes 1d6 necrotic damage at the start of each of its turns, the first damage dealt when it fails the saving throw. It can repeat the saving throw on each of its turns as an action to be free from the spell. If you are incapacitated or you are farther than 5 ft. from the target, the spell ends early.

A creature killed by this spell rises as a poltergeist controlled by you for 24 hours.

At Higher Levels

When you cast this spell using a 3rd-level spell slot or higher, its damage increases by 1d6 for each slot level above the 2nd.
