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 centered 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.
