Far Reaching (3/day). 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.

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’s 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.

Innate Spellcasting. The Abyssal harvester’s spellcasting ability is Wisdom (spell save DC 17). It can innately cast the following spells, requiring no material components: At will: plane shift (functions in Astral Plane, the Abyss, the Nine Hells, or the Material Plane only)

Keen Hearing and Smell. The Abyssal harvester has advantage on Wisdom (Perception) checks that rely on hearing or smell.

Magic Weapons. The Abyssal harvester’s attacks are magical.

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.

Actions

Multiattack. The Abyssal harvester makes four tentacle attacks.

Tentacles. The Abyssal harvester makes an attack with its tentacles using one of the following options: Debilitating Slam. Melee Weapon Attack: +14 to hit, reach 20 ft., one target. Hit: 29 (6d6 + 8) bludgeoning damage and the target’s 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.

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.

Constrict. Each creature the Abyssal harvester has grappled takes 22 (4d6 + 8) bludgeoning damage at the start of the harvester’s turn.
