Preservation. While wearing these wrappings, you have resistance against necrotic damage and age half as fast as normal.

Wraps. When you take the attack action, you can use one attack to attempt to wrap one creature within 30ft. of you with these wrappings by making an unarmed strike. On a successful hit the target is grappled. The escape DC is equal to your Ki save DC. Until the grapple ends, the target is restrained. You can use this feature twice per long rest.

Siphon Life. You can use a bonus action to drain a creature you Grappled with Wrap Attack. You force the creature to make a Constitution saving throw against your Ki save DC. On a success they take no damage but, on a failed save they take 3d6 Necrotic damage, and you regain hit points equal to half of the necrotic damage dealt. You can use this feature twice per long rest.
