Traits

Adaptive Regeneration. The Chorodex regains 15 hit points at the start of its turn. Fire and acid suppress this trait until the start of its next turn.

  • Damage Adaptation. If the Chorodex takes 20 or more damage of a single type in one turn, it gains resistance to that type for the remainder of combat. It cannot gain immunity.

  • Sturdy Condition. After 3 rounds of combat, the Chorodex becomes Sturdy: it ignores any single source of damage less than 20 points. After 6 rounds, it becomes Extremely Sturdy: it ignores any single source of damage less than 50 points.

Legendary Resistances (3/Day). If the Chorodex fails a saving throw, it can choose to succeed instead.

 

Actions

Multiattack. The Chorodex makes two claw attacks and one bite attack.

Claw. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 15 (2d8 + 6) slashing damage.

Bite. Melee Weapon Attack: +9 to hit, reach 5 ft., one target. Hit: 17 (2d10 + 6) piercing damage.

Tentacle. Melee Weapon Attack: +8 to hit, reach 5 ft., one creature. Hit: 13 (2d8 + 4) psychic damage, and the target is grappled (escape DC 15).

Extract Brain. Melee Weapon Attack: One incapacitated creature grappled by the Chorodex takes 55 (10d10) piercing damage. If this reduces the target to 0 hit points, it dies instantly as its brain is devoured.

Mind Blast (Recharge 5–6). The Chorodex emits psionic energy in a 60-foot cone. Each creature in that area must succeed on a DC 15 Intelligence saving throw or take 27 (5d8 + 5) psychic damage and be stunned for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Legendary Actions

The Chorodex can take 3 legendary actions, choosing from the options below. Only one legendary action option can be used at a time and only at the end of another creature’s turn. The Chorodex regains spent legendary actions at the start of its turn.

  • Claw. The Chorodex makes one claw attack.

  • Psionic Jolt. One creature the Chorodex can see within 30 feet must succeed on a DC 15 Intelligence saving throw or take 9 (2d8) psychic damage and have disadvantage on its next attack roll.

  • Flesh Twist (Costs 2 Actions). The Chorodex’s body writhes and adapts. Until the start of its next turn, it gains resistance to the last damage type it took. If already resistant to that type, it instead gains resistance to all physical damage (bludgeoning, piercing, slashing) until the start of its next turn.

  • Mind Shove (Costs 3 Actions). The Chorodex targets one creature within 30 feet. That creature must succeed on a DC 15 Strength saving throw or be pushed 20 feet and knocked prone.

Description

The Chorodex is a paradox of flesh and psionics, born from an experiment so reckless, Elder Brains would never attempt it. Created by a cabal of rogue Illithid, the Chorodex is by far the most horrific result that is both failure and success

When a troll is implanted with a tadpole, the host’s ceaseless regeneration almost always tears the parasite apart before ceremorphosis can complete. The troll dies screaming, or the tadpole is dissolved into nothing.

Only once has the process succeeded. In this rare case, the parasite was no ordinary larva, but a proto-neolithid tadpole that had devoured its kin within the spawning pool. Strong enough to resist regeneration, it fused with the troll and claimed its secret: the ability to heal endlessly.

The result is an aberration that should not exist — a warped troll body animated by psionic will, its flesh forever shifting between troll and illithid. Its troll mind remains trapped, forced to witness its body enslaved to the parasite.

Physically, it's nearly split down the middle, Troll flesh and Illithid skin battling to a stalemate, both equally matched. It's currently impossible to separate them without total death, almost like one needs the other to feed on in some endless...hellish loop. The left side bears that of a trollish body, green skin, but with blackened, bulging veins across the skin. The lone troll eye is bloodshot, looking everywhere, unable to scream. Unable to die. The right side is almost completely ceremorphosed. A hulking arm covered in slime and spines, ending in three sharp claws, a Clawed foot, the right side of the head is practically cephalapodic, 3 tentacles jut from the jawless mouth, formed just enought to subsist on brains to survive. 

The creature is neither tool nor ally; it is a volatile weapon, too dangerous to replicate. The longer it survives in battle, the more its regeneration adapts — hardening bone against bludgeons, thickening skin against blades, slowing its blood against cold. Against a Chorodex, hesitation is death.
