An Abyssal harvester can remain on its Abyssal plane and inject up to four of its tentacles across the dimensions and into the Ethereal Plane, Astral Plane, material planes, or Nine Hells. All of its tentacles must be injected into the same plane, and all appear within the same 20-foot square. While using this ability, it uses sensory organs on its tentacles to see, hear, smell, and feel its surroundings. It can attack normally while using this ability, but it cannot move from its current location. It can withdraw its tentacles as an action and reinject them into the same plane (or a different plane) on its next turn. The dismissal effect of a  dispel evil or good  spell causes an Abyssal harvester to withdraw a single tentacle if it fails its  Charisma  saving throw. It cannot reinject that same tentacle into the same plane for one day. A  banishment  spell forces an Abyssal harvester to withdraw all of its tentacles if it fails its  Wisdom  saving throw. It cannot reinject any tentacles that were banished into the same plane for one day. \n'b'  Harvest . A target that has been  grappled  for 4 consecutive rounds must succeed on a DC 18  Wisdom  saving throw or be drawn through an invisible planar gate (created around the Abyssal harvester\xe2\x80\x99s tentacles) into the same plane where the Abyssal harvester currently resides. An opponent drawn into the same plane with the harvester is still  grappled  upon arrival. This ability can only be used when the Abyssal harvester is on its Abyssal Plane and injects its tentacles into the Ethereal Plane, Astral Plane, a material plane, or the Nine Hells. \n'b'  Innate Spellcasting . The Abyssal harvester\xe2\x80\x99s spellcasting ability is  Wisdom  (spell save DC 17). It can innately cast the following spells, requiring no material components:\n'b'\n'b'   At will :  plane shift  (functions in Astral Plane, the Abyss, the Nine Hells, or the Material Plane only) \n'b'\n'b'  Keen Hearing and Smell . The Abyssal harvester has advantage on  Wisdom  ( Perception ) checks that rely on hearing or smell. \n'b'  Magic Weapons . The Abyssal harvester\xe2\x80\x99s attacks are magical. \n'b'  Tentacles . An Abyssal harvester has 4 tentacles, each of which is 20 feet long, has an AC of 20, 30  hit points ,  resistance  to acid, cold, and fire damage, immunity to poison and psychic damage, and the same senses as the Abyssal harvester. A severed tentacle deals no damage to the Abyssal harvester. A tentacle cannot be broken by mere feats of strengths. A tentacle regrows in 1 week. \n'b'  Actions \n'b'   Multiattack . The Abyssal harvester makes four tentacle attacks. \n'b'  Tentacles . The Abyssal harvester makes an attack with its tentacles using one of the following options:\n'b'\n'b'   Debilitating Slam .  Melee Weapon Attack : +14 to hit, reach 20 ft., one target.  Hit : 29 (6d6 + 8) bludgeoning damage and the target\xe2\x80\x99s maximum  hit points  are reduced by an equal amount. The target dies if this reduces its maximum  hit points  to 0. Otherwise, the reduction lasts until the target finishes a  long rest . \n'b'  Grapple .  Melee Weapon Attack : +14 to hit, reach 20 ft., one target.  Hit : 29 (6d6 + 8) bludgeoning damage and the target is  grappled  (escape DC 22). A  grappled  creature is  restrained . An Abyssal harvester can grapple one creature of Huge  size  or smaller for each tentacle it has remaining. \n'b'  Constrict . Each creature the Abyssal harvester has  grappled  takes 22 (4d6 + 8) bludgeoning damage at the start of the harvester\xe2\x80\x99s turn. \n'b'\n'b'  About \n'b' This creature looks like a puffy and bloated human-sized whitish-yellow maggot with purplish veins pulsating under its ?eshy form. A vaguely humanoid head sits atop its body, and its facial features are twisted and distraught as if the creature was in a constant state of pain. A pair of large, downward-curving horns juts from its head, just above its sunken eyes. Its mouth is lined with filthy and sharpened fangs. \n'b' Abyssal larvae are believed to be the final form of an evil soul deemed too weak to become a demon or even the servant of a demon. Another theory suggests that the larvae are the imprisoned forms of slain demon princes and lords. Whatever their true origin, Abyssal larvae are plentiful throughout the Abyssal planes and are some of the most disgusting and loathsome creatures encountered there. \n'b' These creatures feed on anything they can consume, be it rotting carcasses, freshly slain creatures, and even waste. Consumables are first liquefied through a process requiring the Abyssal larva to regurgitate stomach acids onto its meal. As the food breaks down, the larva slurps it up and consumes it. \n'b' While loathed by the more civilized, some demons such as  dretches  and  babaus  savor the juicy flesh of these creatures and often engage in hunting expeditions across the Abyss, killing and devouring as many as they can find. \n'b' Acting as if almost mindless, Abyssal larvae attack any living creature they encounter. They have no real tactics other than swarming a foe and biting relentlessly. These creatures fight until destroyed.'
