Your Strength, Dexterity and Constitution scores each increase by 1.

Dark magic sustains you, making you resistant to necrotic damage. Healing potions do not have a healing effect on you. Instead, they deal poison damage equal to the amount that was meant to heal. To heal you must either drink blood, spend hit dice, or finish a long rest.

Even though you are undead, you still require sustenance in the form of blood to sustain your unholy existence. You are immune to diseases. You do not need to eat or breathe, but you can ingest food and drink if you wish, though this food is always bland and stale to you. If you go for longer then seven days without drinking at least one ration of blood, you suffer one level of exhaustion on the midnight of that day, which can only be removed by drinking a ration of blood. After consuming one ration of blood, you recover all levels of exhaustion. If you reach six levels of exhaustion due to this trait, you are destroyed.

A ration of blood is a vial, roughly 4 ounces and while that is just enough to sustain you each week, you still feel the urge to drink and may still appear twitchy or ravenous in the heat of battle or when treating a wounded ally. A pint, such as that contained within a flask is considered a healthy amount, enough to keep you sustained while also suppressing your less civilized behavior. Each ration of blood heals you for 1d4+1 hit points while a pint will heal you for 2d4+2 hit points.

You can see in dim light within 60 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.

All vampires have sharpened teeth capable of tearing flesh from bone and draining blood from the body. If a willing, paralyzed, charmed, incapacitated, restrained, or grappled, creature within 5 feet of you has blood, you may use your bonus action to Bite them dealing 1d6 piercing damage and draining their blood dealing additional necrotic damage equal to your Constitution modifier. Drinking blood this way is equal to consuming a ration as per your Blood Drinker trait. When you use your Bite, you can choose to not deal damage.

As a vampire you have a set of claws, your claws are natural weapons, which you can use to make unarmed strikes. If you hit with them, you deal slashing damage equal to 1d4 + your Strength or Dexterity modifier, instead of the bludgeoning damage normal for an unarmed strike.

You are a vampire spawn and as such your will is circumvented by that of your true vampire master. There is little you can do in the way of resisting your master and can't take actions to harm them, however, you can pervert the intent of their commands by exploiting their poor wording. The knowing perversion of such a command though will often lead to your destruction if their master believes it to be so. Any attempt to go against you masters will or pervert their command requires you to make a DC17 Charisma saving throw at disadvantage.

You can speak, read, and write Common, as well as one other language of your choice, that you knew in life.

Although vampires can be incredibly strong, their curse still comes with several notable drawbacks. Regardless of if you are a vampire spawn or a true vampire, you are affected by the following weakness unless specified otherwise:

• Forbiddance: You can't enter a residence without an invitation from one of the occupants.
• Running Water: Your flesh is torn apart in the presence of water, you take 20 acid damage when you end your turn in running water. This damage may not be reduced in any way.
• Stake to the Heart: If a piercing weapon made of wood is driven into your heart while incapacitated in your coffinic structure, you become paralyzed until the stake is removed if you are a true vampire. However, if you are a vampire spawn, you are instead destroyed.
• Sunlight Hypersensitivity: You sear and burn in the light of the sun, your flesh immolating. If you end your turn in direct sunlight, you take 20 radiant damage. You also have disadvantage on any attack rolls and ability checks when in direct sunlight.
