Death Mask

Choose either undead or corpse. You assume the appearance and disposition of the option you chose, appearing so to all outward inspection and magical detection.

If you chose corpse, while moving, it is obvious that you are not a corpse, but you are indistinguishable from one while you remain motionless.

If you chose undead, you have advantage on persuasion checks to diffuse hostilities with intelligent undead.

Regardless of your choice, mindless undead, such as zombies and skeletons, will completely ignore you unless provoked or commanded to attack.
