Undeath

As an undead, your skin becomes tight, eyes dark and sunken, and your blood thickens beneath your rotted exterior. After being reborn, you gain the following traits:

- Whenever you drop to 0 hit points, you instead roll a DC: 13 Constitution saving throw. On a success, you regain one hit point. On a failure, you drop to 0 hit points and fall unconscious.

- You gain resistance to necrotic damage; however, you also only receive half healing from spells. Potions and similar items have full effect on your hit points.

- You are immune to disease and resistant to poison. All medicine checks you make to stitch, suture, amputate, or otherwise operate have a 50% chance of granting a disease to the person you are operating on.
