Traits

Incorporeal Movement.

The dybbuk can move through other creatures and objects as if they were difficult terrain. It takes 5 (1d10) force damage if it ends its turn inside an object.

Magic Resistance.

The dybbuk has advantage on saving throws against spells and other magical effects.

Actions

Tentacle.

Melee Attack Roll: +6 to hit, reach 5 ft., one target. Hit: 13 (2d8 + 4) necrotic damage. If the target is a creature, its hit point maximum is also reduced by 3 (1d6). This reduction lasts until the target finishes a short or long rest. The target dies if its hit point maximum is reduced to 0.

Possess Corpse (Recharge 6).

The dybbuk disappears into an intact corpse within 5 feet of it that belonged to a Large or smaller Beast or Humanoid. The dybbuk gains 20 temporary hit points. While possessing the corpse, the dybbuk adopts the corpse's size and can't use Incorporeal Movement. Its game statistics otherwise remain the same. The possession lasts until the temporary hit points are lost or the dybbuk ends it as a bonus action. When the possession ends, the dybbuk appears in an unoccupied space within 5 feet of the corpse.
