Separating Flying Undead Torso: by day, a manananggal looks like a normal living human or elven woman, and does not detect as (nor act) undead. At sunset the manananggal’s torso rips away from her legs/lower torso and takes flight, transforming into a terrifying half-bodied vampiric entity. In this form the undead is aware of attacks against her lower torso, which shares the same hit points; destroying the lower torso requires applying garlic and salt to the separation point, and doing so will prevent the upper body from grafting at dawn, causing it to turn to dust--so the manananggal takes special care to separate somewhere safe. Physical damage to the lower torso can cause the manananggal to dissipate into a mist which then seeps in to the earth to revive fully  formed at dusk the following evening; only by tainting the lower torso with garlic and salt, preventing reunification, will the creature perish.

Unearthly Vigor.  The manananggal does not breathe.

Spellcasting.  Manananggal are often warlocks and sorcerers, and all manananggal have access to the following spells with a spell attack modifier of +6 and a spell save DC of 14:

At Will: chill touch, dancing lights

3/day at 3rd level: darkness, sleep, ray of enfeeblement, fear

Multiattack – the manananggal may make 1 bite and 2 claw attacks with one action.

Melee Attack – bite +7 to hit (reach 5 feet, one target), 1D8+4 piercing damage and 2d6 necrotic damage and if target is grabbed it must succeed a DC 16 constitution 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.

Melee Attack – claws +7 to hit (reach 5 feet, one target) 1D8+4 slashing damage plus 2d6 necrotic damage or manananggal may grab the target (escape DC 14).
