Attach (Ex): If a larval flayer hits with a touch attack, it uses its four proto-tentacles to latch onto the opponent's body (usually the head). An attached larval flayer is effectively grappling its prey. The larval flayer loses its Dexterity bonus to Armor Class and has an AC of 14, but holds on with great tenacity. Larval flayers have a +12 racial bonus on grapple checks (already figured into the Base Attack/Grapple entry above).

An attached larval flayer can be struck with a weapon or grappled itself. To remove an attached larval flayer through grappling, the opponent must achieve a pin against the larval flayer.

Brain Sap (Ex): A larval flayer eats gray matter, dealing 1d4 points of Intelligence damage each round it remains attached. Once it has dealt 4 points of Intelligence damage, it detaches and slithers off to digest the meal. A larval flayer can reduce its victim to 0 Intelligence in this fashion, which in this case kills the victim. If its victim reaches 0 Intelligence before the larval flayer's appetite has been sated, the larval flayer detaches and seeks a new target.

Psi-like Abilities: 3/day - burst, psionic levitate; 1/day - psionic dimension door (ML 7th). Manifester level 3rd. The save DCs are Charisma-based.

A larval flayer attacks by using psionic dimension door to drop onto a victim from above, finding a vulnerable spot (typically near the neck), and plunging its stubby tentacles into the flesh. This is a touch attack that can target only Small or larger creatures.
