The sibriex emits an aura of corruption 30 feet in every direction. Plants that aren't creatures wither in the aura, and the ground in it is difficult terrain for other creatures. Any creature that starts its turn in the aura must succeed on a DC 20 Constitution saving throw or take 14 (4d6) poison damage. A creature that succeeds on the save is immune to this sibriex's Contamination for 24 hours.
If the sibriex fails a saving throw, it can choose to succeed instead.
The sibriex has advantage on saving throws against spells and other magical effects.
The sibriex's innate spellcasting ability is Charisma (spell save DC 21). It can innately cast the following spells, requiring no material components: • At will: charm person, command, dispel magic, hold monster • 3/Day: feeblemind
The sibriex uses Squirt Bile once and makes three attacks using its chain, bite, or both.
Melee Weapon Attack: +6 to hit, reach 15 ft., one target. Hit: 20 (2d12 + 7) piercing damage.
Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 9 (2d8) piercing damage plus 9 (2d8) acid damage.
The sibriex targets one creature it can see within 120 feet of it. The target must succeed on a DC 20 Dexterity saving throw or take 35 (10d6) acid damage.
The sibriex targets up to three creatures it can see within 120 feet of it. Each target must make a DC 20 Constitution saving throw. On a successful save, a creature becomes immune to this sibriex's Warp Creature. On a failed save, the target is poisoned, which causes it to also gain 1 level of exhaustion. While poisoned in this way, the target must repeat the saving throw at the start of each of its turns. Three successful saves against the poison end it, and ending the poison removes any levels of exhaustion caused by it. Each failed save causes the target to suffer another level of exhaustion. Once the target reaches 6 levels of exhaustion, it dies and instantly transforms into a living abyssal wretch under the sibriex's control. The transformation of the body can be undone only by a wish spell.
Creatures that encounter a sibriex can be twisted beyond recognition. Whenever a creature fails a saving throw against the sibriex's Warp Creature effect, you can roll percentile dice and consult the Flesh Warping table to determine an additional effect, which vanishes when Warp Creature ends on the creature. If the creature transforms into an abyssal wretch, the effect becomes a permanent feature of that body. A creature can willingly submit to flesh warping, an agonizing process that takes at least 1 hour while the creature stays within 30 feet of the sibriex. At the end of the process, roll once on the table (or choose one effect) to determine how the creature is transformed permanently. Flesh Warping: d100 | Effect 01-05 | The color of the target's hair, eyes, and skin becomes blue, red, yellow, or patterned. 06-10 | The target's eyes push out of its head at the end of stalks. 11-15 | The target's hands grow claws, which can be used as daggers. 16-20 | One of the target's legs grows longer than the other, reducing its walking speed by 10 feet. 21-25 | The target's eyes become beacons, filling a 15-foot cone with dim light when they are open. 26-30 | A pair of wings, either feathered or leathery, sprout from the target's back, granting it a flying speed of 30 feet. 31-35 | The target's ears tear free from its head and scurry away; the target is deafened. 36-40 | Two of the target's teeth turn into tusks. 41-45 | The target's skin becomes scabby, granting it a +1 bonus to AC but reducing its Charisma by 2 (to a minimum of 1). 46-50 | The target's arms and legs switch places, preventing the target from moving unless it crawls. 51-55 | The target's arms become tentacles with fingers on the ends, increasing its reach by 5 feet. 56-60 | The target's legs grow incredibly long and springy, increasing its walking speed by 10 feet. 61-65 | The target grows a whiplike tail, which it can use as a whip. 66-70 | The target's eyes turn black, and it gains darkvision out to a range of 120 feet. 71-75 | The target swells, tripling its weight. 76-80 | The target becomes thin and skeletal, halving its weight. 81-85 | The target's head doubles in size. 86-90 | The target's ears become wings, giving it a flying speed of 5 feet. 91-95 | The target's body becomes unusually brittle, causing the target to have vulnerability to bludgeoning, piercing, and slashing damage. 96-00 | The target grows another head, causing it to have advantage on saving throws against being charmed, frightened, or stunned.
