Mind Flayers

Mind Flayers, also known as Illithids, are monsters with innate Psionic Ability and their dreaded multi-tentacled melee attack that can "devour brain" (temporarily drain intelligence) or kill if the target's intellect is reduced to zero. They are initially encountered during the Shadows of Amn campaign. Some are found in the Athkatla sewers in the Mind Flayer's Lair, in the mind flayer dungeon in the Underdark main caverns and specifically the Eastern Tunnels, in Watcher's Keep Illithid Encampment and in Sendai's Enclave and the Sendai's Lair Mithykyl area. More are encountered in the Enhanced Edition during the Hexxat's request questline within the Crypt of Durkon. Some other types include the highly magic-resistant and spell-casting Ulitharids, Vampiric Illithid, and the Alhoon. An Umber Hulk group is often found in areas with Mind Flayers, and they carry no gold nor drop any treasure.
