Electric Invigoration. Whenever the Body Snatcher takes lightning damage it gains 16 (3d10) temporary hit points and automatically recharges its electric torrent ability.
Skin Sack. The body snatcher is physically indistinguishable from its host and cannot be externally differentiated by nonmagical means. If the Body Snatcher is reduced to 0 hit points, and it has been inside its current host for less than 24 hours, the host regurgitates it, then falls unconscious with 1 hit point.
Multiattack. The Body Snatcher makes two slam attacks.
Slam. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 10 (2d6 + 3) bludgeoning damage, and the target must succeed at a DC 15 Strength saving throw or become grappled (escape DC 15). A creature that is hit with a slam attack while suprised is automatically grappled. The Body Snatcher can only grapple one creature at a time.
Invade. The Body Snatcher’s jaw opens into a wide, three pronged maw as it attempts to latch onto the mouth of a creature it is grappling. The target must make a Strength (Athletics) or Dexterity (Acrobatics) check, contested by a Strength (Athletics) check made by the Body Snatcher. If the Body Snatcher succeeds, it ejects from its current host, leaving an empty sack of
skin, and moves into the grappled creature; the grappled creature becomes the Body Snatcher. The body snatcher regains all hit points and automatically recharges its electric torrent ability.
Electric Torrent (Recharge 5-6). The Body Snatcher unleashes a large electric pulse. Each other creature within a 20-foot sphere centred on the Body Snatcher must make a DC 15 Dexterity saving throw, taking 28 (8d6) lightning damage on a failed save, or half as much on a successful one.
Description
Like other creatures spawned from vile curses, Body Snatchers are the result of a humanoid who has succumbed to a Curse of Damned Aging. However, much to the dismay of investigators, Body Snatchers are notoriously difficult to locate, as they hide in plain sight. When on the trail of a Body Snatcher, investigators often close in on the suspect only arrive a step too late, and find a withered and discarded skin sack.
Body Snatchers are ooze-like creatures that inhabit the bodies of victims, living inside them like a parasite feeding on their life force.
The Body Snatcher takes complete control of its host body, which it enhances with supernatural capabilities. The only sign that an individual has been invaded by a body snatcher is their erratic behaviour and rapid aging—a host can age a lifetime in a matter of a few weeks.
Fighting a Body Snatcher is easier said than done. While far from helpless, Body Snatchers prefer to avoid detection and will engage enemies only in dire situations or when changing hosts. They do their gruesome business in seclusion as much as possible.
