Extract (Ex): If Shuluth begins its turn with all four tentacles attached and makes a successful grapple check, it automatically extracts the opponent's brain, instantly killing that creature.

Improved Grab (Ex): To use this ability, Shuluth must hit a Small, Medium, or Large creature with its tentacle attack. It can then attempt to start a grapple as a free action without provoking an attack of opportunity. If it wins the grapple check, it establishes a hold and attaches the tentacle to the opponent's head. Shuluth can grab a Huge or larger creature, but only if it can somehow reach the foe's head.

If Shuluth begins its turn with at least one tentacle attached, it can try to attach its remaining tentacles with a single grapple check. The opponent can escape with a single successful grapple check or an Escape Artist check, but Shuluth gets a +2 circumstance bonus for every tentacle that was attached at the beginning of the opponent's turn.

Mind Blast (Sp): 60-ft. cone, stun 3d4 rounds, Will DC 17 negates. This ability is the equivalent of a 4th-level spell.

Psionics (Sp): At will - charm monster (DC 17), detect thoughts (DC 15), levitate, plane shift, suggestion (DC 16). Caster level 8th.

Deflection: Shuluth enjoys an inherent +1 deflection bonus to its AC.

Mirror Image (Sp): Once per day by uttering a vile command word, Shuluth can use mirror image as the spell. Caster level 5th.

Omen: All creatures within 15 feet of Shuluth that have a language "hear" dire mental whispers forecasting their sudden and painful demise. Shuluth can suppress or emit this telepathic aura as a free action.

See Invisibility (Sp): Once per day by uttering a vile command word, Shuluth can use see invisibility as the spell. Caster level 5th.

Telepathy (Su): Shuluth can communicate telepathically with any other creature within 100 feet that has a language.

Shuluth enhances the normal combat tactics of an illithid with its improved defensive abilities.
