Actions

• Multiattack: The Thulgant makes three attacks: one with its stinger and two with its tentacles.
• Stinger: Melee Weapon Attack: +12 to hit, reach 10 ft., one target. Hit: 3d12 + 8 piercing damage. The target must succeed on a DC 20 Constitution saving throw or be poisoned for 1 minute. While poisoned in this way, the target takes 3d6 psychic damage at the start of each of its turns.
• Tentacle: Melee Weapon Attack: +10 to hit, reach 10 ft., one target. Hit: 2d8 + 6 bludgeoning damage plus 2d6 acid damage. The target is grappled (escape DC 18). Until this grapple ends, the Thulgant can’t use this tentacle to make attacks.
• Mind-Rending Sting: Recharge 5–6. The Thulgant targets one creature it poisoned with its stinger attack. The target must succeed on a DC 20 Intelligence saving throw or take 6d10 psychic damage and be stunned until the end of the Thulgant’s next turn.
• Stunning Display: Recharge 6. The Thulgant presents its numerous tentacles and stingers in a horrifying display. Each creature within 30 feet of the Thulgant that can see it must succeed on a DC 20 Wisdom saving throw or be stunned for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on a success.

---

Lair Actions

On initiative count 20 (losing initiative ties), the Thulgant can take a lair action to cause one of the following effects; the Thulgant can’t use the same effect two rounds in a row:

• Summon Minions: The Thulgant summons 1d4 + 1 quasit demons in unoccupied spaces within 60 feet of it. The summoned demons act immediately after the Thulgant’s turn and remain for 1 hour, until they die, or until the Thulgant dismisses them (no action required).
• Terrifying Visage: The Thulgant’s horrific appearance intensifies. Each creature of the Thulgant’s choice within 30 feet that can see it must succeed on a DC 20 Wisdom saving throw or be frightened for 1 minute. A creature can repeat the saving throw at the end of each of its turns, ending the effect on a success.
• Abyssal Surge: The Thulgant channels the chaotic energy of the Abyss. Each creature within 20 feet of the Thulgant must succeed on a DC 20 Dexterity saving throw or take 3d6 fire damage and be knocked prone. A creature that succeeds on the saving throw takes half as much damage and isn’t knocked prone.

---

Regional Effects

The region containing a Thulgant’s lair is warped by the creature’s presence, which creates one or more of the following effects:

• Warped Terrain: The terrain within 1 mile of the lair becomes twisted and unnatural. Plants grow in unnatural patterns, and the land shifts unpredictably.
• Distorted Time: Time behaves erratically near the lair. Creatures within 1 mile of the lair experience time dilation effects, such as periods where time seems to slow or speed up unpredictably.
• Chaotic Weather: The weather within 1 mile of the lair becomes erratic and dangerous. Storms may appear without warning, and the weather can change rapidly and violently.

---

Tactics

• Opening Move: The Thulgant begins combat by using its Stunning Display to incapacitate multiple foes, then follows up with Mind-Rending Sting to eliminate the most vulnerable target.
• Mid-Combat Strategy: It uses Tentacle attacks to grapple and restrain enemies, setting them up for devastating Stinger strikes.
• Spell Usage: The Thulgant employs spells like Greater Invisibility and Counterspell to control the battlefield and neutralize threats.
• Lair Defense: When in its lair, the Thulgant utilizes Summon Minions to overwhelm intruders and Terrifying Visage to maintain psychological pressure.

SPECIAL ABILITIES

• Abyssal Magic (Sp): At will—greater invisibility, telekinesis (caster level 20th); 3/day—disintegrate, plane shift (self plus 50 lbs. of objects only); 1/day—wish. The Thulgant’s caster level for these effects is 20th, and its caster level check to overcome spell resistance is +28.
• Dimensional Step (Su): As a swift action, the Thulgant can teleport up to 60 feet to a location it can see. This ability functions similarly to the spell dimension door but does not provoke attacks of opportunity.
• Poison (Ex): Injury—bite, sting, or tentacle; save Fort DC 29; frequency 1/round for 6 rounds; effect 1d6 Con damage; cure 2 consecutive saves. The save DC is Constitution-based.
• True Seeing (Su): The Thulgant continuously benefits from the effects of a true seeing spell.

TACTICS

Before Combat The Thulgant uses its greater invisibility to approach enemies undetected. It may also use telekinesis to manipulate objects or disarm opponents from a distance.

During Combat The Thulgant opens combat by using its dimensional step to position itself advantageously. It then employs its bite and tentacle attacks to poison and constrict foes. It uses its spell-like abilities to control the battlefield, casting disintegrate on weakened enemies and plane shift to banish those who attempt to flee.

Morale The Thulgant fights to the death, driven by its singular purpose to eradicate all demons from the Abyss.
