The illithid stands at 6'2", with the slimy skin always associated to his kind. The grayish skin, with shades of purple under the right light, usually glistens, looking moist and icky by human standards.
The four tentacles covering his mouth are thick at the base, long enough to reach his belly. Usually just hanging quietly, they seem to move as if they had life by themselves if Hauatlont is caught performing any task he deems interesting or communicating with others, tangling between each other or undulating, spread before his chest.
What separates him from other members of his race are the eight longer tentacles growing from his back. Even when he is able to hide part of them inside his body, they are always visible and the clothing he wears is pierced to let them move freely around him. Those tentacles, adquired in a wicked experiment, look strong and flexible, able to turn in the most strange angles. They have become a part of his body, as they are fully sensitive and he owns complete control over them.

Recently his eyes are showing silver colour, as if they were made of quicksilver. The veins of his tentacles and body show lines of the same silver glow that radiates and makes the oil coating his skin glow brighter.

Abilities (up to you to decide if your character could be vulnerable or not to them, feel free to send a tell if she is):

Psionic: There's a psionic aura around the illithid, which might cause not properly shielded minds to feel a tingle or a buzz when he is around if he makes contact with them. He is able to communicate with creatures within psionic reach. The strenght of the bond increases the closer they are or if they have had any previous contact.
Depending on the will of the creature contacted he might be able to read surface thoughts

Mind-crafting: He's capable of altering the memories and perception of those in psionic contact with him, soothing them or incepting concepts and ideas. The process requires a subtle crafting to avoid hurting the mind of the victim.

Corruptive ooze: His tentacles can pour a corruptive yellowish ooze. If ingested the victim will experiment a subtle increase in their body temperature. Changes vary depending on the race and resistances of the victim.

Double breeding: He's capable of both laying eggs and produce fertile cum.

Lights: Vaginal, anal, oral, breeding, impregnation, oviposition, cum-eggs inflation, watersports, messy sex, ooze, subtle mind control - hypnosis, multiple penetrations.

Red: server banned stuff, completely mindless slaves, brainwashing and bimbofication, males
