Undead. Your creature type is undead. You are immune to disease. You do not need to eat or breathe, but you can ingest food and drink if you wish. Instead of sleeping, you enter an deathlike state for 8 hours each day. You do not dream in this state; you are not aware of your surroundings and approaching enemies.

Darkvision. You have superior vision in dark and dim conditions. You can see in dim light within 120 feet of you as if it were bright light, and in darkness as if it were dim light. You can’t discern color in darkness, only shades of gray.

Thirst. You can drain blood and life energy from a willing creature, or one that is grappled by you, incapacitated, or restrained. Make a melee attack against the target. If you hit, you deal 1 piercing damage and 1d6 necrotic damage. The target’s hit point maximum is reduced by an amount equal to the necrotic damage taken, and you regain hit points equal to that amount. The reduction lasts until the target finishes a long rest. The target dies if this effect reduces its hit point maximum to 0.

Hypnotic Creature. You know the Friendship cantrip. When you reach 3rd level, you can cast the Suggestion spell once per day. When you reach 5th level, you can also cast the Gaseous Form spell once per day. Charisma is your spellcasting ability for these spells.

Sunlight Sensitivity. You have disadvantage on attack rolls and on Wisdom (Perception) checks that rely on sight when you, the target of your attack, or whatever you are trying to perceive is in direct sunlight.

Unholy Resistance. You have resistance to necrotic damage.

Accursed Being. Due to your undead nature, you have a vulnerability to radiant damage.
