Actions

Multiattack. The tattooed thrall makes two attacks, only one of which can be a bite attack.   Greatsword. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 14 (2d6 + 7) slashing damage.   Claws. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: 12 (2d4 + 7) slashing damage. Instead of dealing damage, the tattooed thrall can grapple the target (escape DC 14).   Bite. Melee Weapon Attack: +7 to hit, reach 5 ft., one willing creature, or a creature that is grappled by the tattooed thrall, incapacitated, or restrained. Hit: 10 (1d6 + 7) piercing damage plus 7 (2d6) necrotic damage. The target's hit point maximum is reduced by an amount equal to the necrotic damage taken, and the tattooed thrall 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.   If the target is a humanoid, it must succeed on a DC 13 Constitution saving throw or be infected with a disease called vampirism. While infected, the target can't regain hit points, and its hit point maximum is reduced by 10 (3d6) every 24 hours. If the disease reduces the target's hit point maximum to 0, the target instantly transforms into a vampire spawn, and is charmed by the tattooed thrall. Although the target isn't under the tattooed thrall's control, it takes the tattooed thrall's requests or actions in the most favorable way it can, and it is a willing target for the tattooed thrall's bite attack.   Each time the tattooed thrall or any of its companions do anything harmful to the target, it can make a DC 13 Wisdom saving throw, ending the effect on itself on inself on a success. Otherwise, the effect lasts until the tattooed thrall is destroyed or takes a bonus action to end the effect.   Tattoo of Sins: Lust. A creature the tattooed thrall chooses, in which both the tattooed thrall and the creature can see each other, must pass a Wisdom saving throw of DC 11 or be charmed by the tattooed thrall for 1 hour. Creatures charmed by this effect believe the tattooed thrall to be their true love if the tattooed thrall is someone they would normally be attracted to. They lose charm if attacked by the tattooed thrall and understand that they were charmed by the tattooed thrall once the effect ends.

When it activates this tattoo, the tattooed thrall chooses an amount of coins to permanently sacrifice. For each platinum coin or equivalent sacrificed, the tattooed thrall gains 1 additional necrotic damage dealt on its next attack. If the next attack misses, the tattooed thrall instead takes the necrotic damage equal to the number of platinum coins sacrificed. For each 50 additional damage dealt during a singular attack through this ability, the tattooed thrall gains a point of exhaustion on a successful hit.   Tattoo of Sins: Sloth.
