Melee Weapon Attack: +9 to hit, reach 5 ft., one willing creature, or a creature that is unable to move. Hit: 9 4d8 necrotic damage. The target's maximum hp is reduced by the amount of damage dealt, and the vampire regains that much hp. The reduction lasts until the target finishes a long rest. The target dies if this effect reduces its hit point maximum to 0. A humanoid slain in this way and then buried in the ground rises the following night as a Vampire Spawn under the vampire's control.   Charm. The vampire targets one humanoid it can see within 30 feet of it. If the target can see the vampire, the target must succeed on a DC 20 Wisdom saving throw against this magic or be charmed by the vampire. The charmed target regards the vampire as a trusted friend to be heeded and protected. Although the target isn't under the vampire's control, it takes the vampire's requests or actions in the most favorable way it can, and it is a willing target for the vampire's bite attack.   Each time the vampire or the vampire's companions do anything harmful to the target, it can repeat the saving throw, ending the effect on itself on a success. Otherwise, the effect lasts 24 hours or until the vampire is destroyed, is on a different plane of existence than the target, or takes a bonus action to end the effect.   Children of the Night (1/Day). The vampire magically calls 1d4 Vampire Spawn. The called creatures arrive in 1d2 rounds, acting as allies of the vampire and obeying its spoken commands. They remain for 1 hour, until the vampire dies, or until the vampire dismisses them as a bonus action.   Changed form; While in mist form, the vampire can't take any actions, speak, or manipulate objects.
