Chishinix the Clairvoyant Mother

Encephalon Womb. Chishinix has a Encephalon Cluster growing in her stomach, breaking through the skin and making up most of her mid torso. The cluster shares initiative with Chishinix but takes its turn immediately after her and can be targeted separately from Chishinix. It has the following modifications:

• 160 hit points, AC 15.
• Immune to Psychic damage.
• Resistant to Bludgeoning, Piercing, and Slashing damage from nonmagical attacks.
• Has total cover from attacks from all directions except from in front of Chishinix.
• It shares Chishinix's space, has a speed of 0 and moves with her.
• The cluster can still uses its multiattack against any creature within its reach, except for mind flayers.
• The cluster's Spawn Progeny action no longer requires a recharge, but can only be used every three rounds after its first use.
• Modified Action/Reaction:
  • Slam. If this attack reduces the target to 0 hit points, the target immediately dies and is consumed by the cluster. Then both the cluster and Chishinix regain hit points equal to the damage dealt, divided evenly between them (rounded down).
  • Aggressive Hunger. Immediately after Chishinix or the cluster womb is hit by an attack, the cluster use its reaction to make Chishinix move up to her speed toward the attacker. This movement doesn’t provoke opportunity attacks. If Chishinix ends this movement within 10 feet of the attacker, she then make one Slam attack against that attacker. If Chishinix ends this movement within 5 feet of the attacker, both she and the cluster make one Slam attack against the attacker.

If the cluster dies, Chishinix will take double the damage from attacks that come from the front of her, her Strength becomes 18 (+4), and she loses her Blindsight. Chishinix can replace the cluster with a new one after a long rest of undisturbed surgery.

Legendary Resistance (3/Day). If Chishinix fails a saving throw, she can choose to succeed instead.

Magic Resistance. Chishinix has advantage on saving throws against spells and other magical effects.

Psionic Link. Mind flayers and Encephalon Gemmules spawned by the Encephalon Womb within range of Chishinix's telepathy take no damage from any of her actions that deal psychic damage.

Psionic Might. Psychic damage that Chishinix deals to a creature bypasses a creature's resistance to psychic damage and deals half damage to creature's with immunity.

Twin-headed Nightmare. Chishinix has advantage on maintaining concentration on a spell, and can maintain concentration on two spells at once.

Multiattack. Chishinix makes three attacks, using any combination her Tentacle, Slam, or Mind Bolt attacks. She can substitute two attacks for an Extract Brain attack.

Slam. Melee Weapon Attack: +14 to hit, reach 10 ft., one target. Hit: 24 (4d8 + 6) bludgeoning damage. If the target is Medium or smaller, it has the grappled condition (escape DC 19) and is restrained until the grapple ends.

Tentacles. Melee Weapon Attack: +13 to hit, reach 10 ft., one creature. Hit: 21 (3d10 + 5) psychic damage. If the target is Large or smaller, it has the grappled condition (escape DC 19) and must succeed on a DC 20 Intelligence saving throw or have the incapacitated condition until the grapple ends.

Extract Brain. Melee Weapon Attack: +13 to hit, reach 5 ft., one incapacitated Humanoid or Giant grappled by Chishinix. Hit: 55 (10d10) piercing damage. If this damage reduces the target to 0 hit points, Chishinix kills it by extracting and devouring its brain, then both she and the cluster regain hit points equal to the damage dealt, divided evenly between them (rounded down).

Mind Bolt. Ranged Spell Attack: +13 to hit, range 120 ft., one creature. Hit: 18 (2d12 + 5) psychic damage, and the target must succeed on a DC 20 Intelligence saving throw or be stunned until the end of its next turn.

Spellcasting (Psionics). Chishinix casts one of the following spells, requiring no spell components and using Intelligence as the spellcasting ability (spell save DC 20):

At will: detect magic, detect thoughts, mage hand (the hand is invisible), Pulse Wave, Magnify Gravity (4th level)

3/day each: clairvoyance (as an action), dispel magic (6th level), dominate monster, Gravity Fissure

1/day each: plane shift (self only), Reality Break

Duel Mind Blast (Recharge 5–6). Chishinix magically emits psychic energy in two 60-foot cones. These cones cannot overlap. Each creature in a cone's area must succeed on a DC 20 Intelligence saving throw or take 31 (4d12 + 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.

Unleash Void (Recharge 5–6). Chishinix opens a rift into the Far Realm, centered on a point she can see within 60 feet of herself, and a tentacle lashes across creatures near the rift. Each creature within 30 feet of the rift must make a DC 20 Intelligence saving throw, after which the tentacle disappears and the rift closes. On a failed save, a creature takes 24 (6d8) cold damage from the rift plus 24 (6d8) psychic damage from the tentacle and has the stunned condition for 1 minute. On a successful save, a creature takes half as much damage only. A stunned creature can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.

Warp Reality. When hit by an attack roll, Chishinix gains a +4 bonus to her AC against that attack roll, potentially causing it to miss. Then Chishinix, along with any equipment she is wearing or carrying, magically teleports up to 60 feet to an unoccupied space she can see.

Chishinix 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. Chishinix regains spent legendary actions at the start of her turn.

Slam. Chishinix makes one Slam attack.

Crushing Tentacle. Chishinix crushes one creature she is grappling with her tentacles. The grappled creature must make a DC 21 Constitution saving throw, taking 16 (3d6 + 6) force damage on a failed save, or half as much damage on a successful one. The creature makes the saving throw with disadvantage if it is grappled by Chishinix's tentacles and takes double the damage on a failed save.

Teleport (Costs 2 Actions). Chishinix teleports, along with any creatures she is grappling, to an unoccupied space she can see within 120 feet of herself.
