Your vampire character has the following traits.
Ability Score Increase. Your Charisma score increases by 2, and either your Wisdom score (Ixalan) or your Intelligence score (Zedikar) increases by 1.
Age. Vampires don’t mature and age in the same way that other races do.
Alignment. Vampires might not have an innate tendency toward evil, but many of them end up there. Evil or not, their strict hierarchies incline them toward a lawful alignment.
Size. Vampires are the same size and build as humans. Your size is Medium.
Speed. Your base walking speed is 30 feet.
Darkvision. Thanks to your heritage, you have superior vision in dark and dim conditions. 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.
Vampiric Resistance. You have resistance to necrotic damage.
Languages. You can speak, read, and write Common and Vampire.
Bloodthirst. 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.
Feast of Blood. When you drain blood with your Bloodthirst ability, you experience a surge of vitality. Your speed increases by 10 feet, and you gain advantage on Strength and Dexterity checks and saving throws for 1 minute.
Undead You no longer require air, food, drink or sleep.
Vampiric Exultation
Prerequisite: Vampire (Ixalan)
As an action, you can transform the lower half of your body into an inky black vapor, allowing you to float through the air. While transformed, you have a flying speed of 30 feet. You can maintain this form for up to 10 minutes. Once you use this ability, you can’t use it again until you finish a short or long rest.
