Adhesive (Su) A weapon that strikes an adherer becomes stuck fast to the creature's adhesive flesh unless the wielder succeeds at a DC 14 Reflex save. A creature adjacent to the adherer can attempt to pry off a stuck weapon with a DC 17 Strength check, but doing so provokes an attack of opportunity from the adherer. The adherer's adhesive flesh gives it a +8 racial bonus on grapple checks. It can attempt to grapple a foe as a free action whenever a creature successfully hits it with a natural attack or an unarmed strike. An adherer does not gain the grappled condition when it grapples a foe, nor does it provoke attacks of opportunity when it attempts to do so.
Merci Syel, tu as raison.
