Strigoi

The strigoi is an animalistic variant of the vampire. Strigoi are humanoid figures, with ambiguous genitalia, and ashen grey skin. These creatures usually hunt in packs of 4 to 5, and nest in broods are large as 100. The strigoi are motivated almost exclusively by feeding and will decimate whole communities to satiate their hunger. A significant feature of the strigoi is its multi-mandibular mouth, which can open wide to engulf a humanoid's entire head. Each mandible is filled with rows of sharp, barbed teeth, intended to siphon blood from the victim after a successful grapple. The strigoi also have an incredibly long articulated tongue with a hooked barb on the end, which is used as both ranged melee weapon and a feeding mechanism. The barb on a strigoi's tongue is also the primary means for cursing a victim with a sub-form of vampirism that will turn the victim into a strigoi. However, these creatures typically feed until the victim has been bled dry, leaving nothing to turn.

Actions

Multiattack. The vampire makes two attacks, only one of which can be a bite attack.
Claws. Melee Weapon Attack: +6 to hit, reach 5 ft., one creature. Hit: 8 2d4+3 slashing damage. Instead of dealing damage, the vampire can grapple the target (escape DC 13).
Bite. Melee Weapon Attack: +6 to hit, reach 5 ft., one willing creature, or a creature that is grappled by the vampire, incapacitated, or restrained. Hit: 6 1d6+3 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 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.
Tongue attack. Melee Weapon Attack: +6 to hit, reach 10 ft., two creatures that are adjacent. Hit 8 1d6+3 slashing damage, if target is successfully hit, the target takes an additional 3 1d6 acid damage, and must save on a DC 13 Fort Save or become infected with vampirism.

Regional Effects

The region surrounding a strigoi’s lair is warped by the creature’s unnatural presence, creating any of the following effects:
There’s a noticeable increase in the populations of bats, rats, and insect swarms in the region. Plants within 500 feet of the lair wither, and their stems and branches become twisted and thorny. Shadows cast within 500 feet of the lair seem abnormally gaunt and sometimes move as though alive. A creeping fog clings to the ground within 500 feet of the vampire’s lair. The fog occasionally takes eerie forms, such as grasping claws and writhing serpents. If the strigoi is destroyed, these effects end after 2d6 days.
