Actions
Multiattack. The vampire mastiff makes two attacks, only one of which can be a bite-drain attack.
Claws. Melee Weapon Attack: +5 to hit, reach 5 ft., one creature. Hit: 6 (1d6 + 3) slashing damage. Instead of dealing damage, the vampire can grapple the target (escape DC 13).
Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 6 (1d6 + 3) piercing damage. If the target is a creature, it must succeed on a DC 13 Strength saving throw or be knocked prone. If knocked prone, the vampire mastiff may automatically grapple the target. Instead of dealing damage, the vampire can grapple the target (escape DC 13).
Bite-drain. Melee Weapon Attack: +5 to hit, reach 5 ft., one willing creature, or a creature that is grappled by the vampire mastiff, incapacitated, or restrained. Hit: 6 (1d6 + 3) piercing damage plus 3 (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 hit point maximum to 0.
