Your Dexterity score increase by 1, and Charisma or Wisdom or Intelligence score increases by 2.

Vampires are immortal and can be any age. Vampires retain the physical appearance of the age at which they were turned at during their mortal life. They also retain the psychological development associated with that age, therefore vampires who did not reach adulthood in their mortal life may still have the impulses of an adolescent in their vampiric life

You can't enter a residence without an invitation from one of the occupants.

You cannot cross water unless it is at high or low tide.

If a piercing weapon made of wood is driven into your heart while incapacitated, you become paralyzed until the stake is removed.

Your creature type is considered to be both humanoid and undead. 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 and intoxication. 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 no longer gain any more levels of exhaustion and become indefinitely paralyzed. The only way to remove this paralyze is to be exposed to a rations worth of blood.

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 2d4+2 hit points while a pint will heal you for 4d4+4 hit points.

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.

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 Connoisseur trait. When you use your Bite, you can choose to not deal damage. The damage for your Bite increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).

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 1d6 + your Strength or Dexterity modifier, instead of the bludgeoning damage normal for an unarmed strike.
