A compelled does not have blood. Instead, it 'bleeds' a dark ichor substance that has healing properties towards Undead, and does necrotic damage if in contact with the Living. As a bonus action, if you have been previously hit with piercing or slashing damage, you may activate your ichor to apply 1d4+[CON Modifier] healing to yourself or another Undead within 5ft, or 1d4+[CON Modifier] damage to a living creature within 5 feet. You gain uses of this ability equivalent to your proficiency bonus per long rest. The die increases to 2d6 at level 5, and 3d8 at level 15.

Because of your undead body, you do not need to eat, sleep, drink, or breathe. You are always fully awake and do not require a long or short rest, just for that off time to pass, however you can be magically put into a trance by sleeping spells.

Spells such as Cure Wounds and Healing Word have no effect on you, but spells such as Inflict Wounds will work as a Cure Wounds with the typical die of Cure Wounds. Additionally, you are resistant to poison damage and immune to all forms of disease. You are immune to the Poisoned condition. However, you are vulnerable to Radiant Damage.

You can speak, read, and write Common, Abyssal and Celestial.
