Monsters: Mind Flayers (Illithids)

Monsters: Mind Flayers (Illithids)

Mind flayers, also known as illithids, are iconic D&D monsters. They have powerful telepathic abilities and their signature brain extraction move. Avoid them, unless you have prepared mental defenses. I suggest reading Lords of Madness for D&D 3.5 or The Illithiad for AD&D 2e. Both are great reads.

Typical Stats – Mind Flayer

ST:	11	HP:	11	Speed:	5.75
DX:	11	Will:	15	Move:	5
IQ:	14	Per:	12
HT:	12	FP:	12	SM:	+0
Dodge:	8	Parry:	8 (unarmed)	DR:	1* (tough skin)

    Punch (11): thrust 1d-2 crushing, Reach C.
    Tentacles (11): The mind flayer has four short tentacles that encircle its mouth. These are treated as four short arms with Reach C and effective ST of 5. The mind flayer can use tentacles to attack for 1d-5 crushing damage (KYOS: 1d-8 crushing damage), but usually uses the tentacles for grappling and manipulating objects. The tentacles are considered to be “off-hands” for the purpose of penalties, but not for the purpose of determining the arc of attack.
    Dissolving Enzyme (11): The mouth tentacles have ducts that can transmit a powerful dissolving enzyme. This takes time – the mind flayer must first perform a Ready maneuver, and only then follow-up with a Reach C melee attack with one or more of its tentacles. If it succeeds, it deals 2d corrosion damage. If it only has three tentacles in contact with the victim, then decrease it by 25%; if it only has two tentacles in contact with the victim, then decrease it by 50%; if it only has one tentacle in contact with the victim, then decrease it by 75%. Usually, the mind flayer uses this attack when grappling the skull with all four tentacles to corrode its way through the skull and extract the brain. Each use costs 2 FP.
