Regeneration. The vampire regains 10 hit points at the start of its turn if it has at least 1 hit point and isn't in sunlight or running water. If the vampire takes radiant damage or damage from holy water, this trait doesn't function at the start of the vampire's next turn.

Spider Climb. The vampire can climb difficult surfaces, including along ceilings, without needing to make an ability check.

Vampire Weakness. The vampire has these weaknesses:

Forbiddance. The vampire can’t enter a residence without an invitation from an occupant.
Running Water. The vampire takes 20 Acid damage if it ends its turn in running water.
Stake to the Heart. The vampire is destroyed if a weapon that deals Piercing damage is driven into the vampire’s heart while the vampire has the incapacitated condition.
Sunlight. The vampire takes 20 Radiant damage if it starts its turn in sunlight. While in sunlight, it has disadvantage on attack rolls and ability checks.

Multiattack. The vampire makes two Claw attacks and uses Bite.

Claws. Melee Weapon Attack: +6 to hit, reach 5 ft., one creature. Hit: 8 (2d4 + 3) slashing damage. Instead of dealing damage, the vampire can grapple the target (escape DC 13).

Bite. Melee Weapon Attack: +6 to hit, reach 5 ft., one willing creature. Hit: 6 (1d6 + 3) piercing damage. If the target hit has the grappled condition, it deals an extra 2d6 necrotic damage and the target is no longer grappled. After that the vampire regain hit points equal to half of the necrotic damage dealt to the target.
