Regeneration. The vampire regains 7 (2d6) 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.
Multiattack. The vampire makes 2 attacks, only one of which can be a Bite attack.
Bite. Natural Melee Weapon: +5 to hit, Reach 5 ft., one willing creature, or a creature that is grappled by the vampire, incapacitated, or restrained.
Hit: 7 (2d6+3) piercing plus 4 (1d6) necrotic damage. The target's hit point maximum is reduced by an amount equal to the necrotic damage taken, and the vampire regains hit points equal to that amount. The reduction lasts until the target finishes a long rest. The target dies if this effect reduces its Max HP to 0.
