The skeletal intellect devourer is a hideous creature that resembles a moldering brain in a bony shell with scraps of flesh hanging from its form. Stripped of the weaknesses of flesh and wielding power from beyond the grave, the skeletal intellect devourer retains its impressive psionic abilities, making it even more dangerous and terrible than when it was when it was living.

Unlike other undead, the skeletal intellect devourer retains its speed and agility and gains strength and immunities far surpassing its living kin. However, it is a coward; it fears divine casters for the burning touch of their turning ability.

Because these creatures can only inhabit corpses, skeletal intellect devourers make their lairs near a ready supply of bodies (such as cemeteries or sewers), and large concentrations of corpses can bring these normally solitary creatures together.
