Amorvrin

Shadow of Bukrai. The amorvrus can activate or deactivate this feature as a bonus action. While active, the Shadow deals 5 necrotic damage to any creature that ends its turn within 5 feet of the amorvrus. Undead and fiends ignore this effect.

A humanoid slain by the Shadow of Bukrai suffers the same effect as if killed by the amorvrus’ Life Drain.

Shadow Sense. The amorvrus can use Blindsight to see creatures and objects around them that aren't protected from divination magic.

Multiattack. The amorvrus makes two longsword attacks or two longbow attacks. It can use its Life Drain in place of one longsword attack.

Life Drain. Melee Weapon Attack: +4 to hit, reach 5 ft., one creature. Hit: 9 (2d8) necrotic damage. The target  must succeed on a DC 14 Charisma saving throw or its hit point maximum is reduced by an amount equal to the damage taken. This 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 by this attack rises 1 minute later as a gulmorvrus (see Gulmorvrin) under the amorvrus' control, unless it is restored to life or its body is destroyed in the meantime. The amorvrus can have no more than six gulmorvrin under its control at one time.

Longsword. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: 7 (1d8 + 3) slashing damage, or 8 (1d10 + 3) slashing damage if used with two hands.

Longbow. Ranged Weapon Attack: +4 to hit, range 150/600 ft., one target. Hit: 6 (1d8 + 2) piercingdamage.
