Special Abilities
<p><b>Drink Marrow (Ex)</b> A flayer leech has a pharyngeal proboscis that can quickly vibrate at a subsonic frequency, allowing it to easily pierce through bone and similar hardened internal structures to consume a creature’s marrow. A creature struck by a flayer leech’s bite must succeed at a DC 15 Fortitude save or be sickened for 1 minute. Further bites from the flayer leech don’t worsen this condition, only extend the duration.<br/><br/> <b>Mandible Dance (Su)</b> As a full action, a flayer leech can stand its body vertically, opening each of its five petal-like jaws and gesticulating with its vast array of complex mouth parts and hooked teeth in a strange performance. Each creature within 30 feet of the flayer leech must succeed at a DC 13 Will save or be fascinated for as long as the flayer leech continues its dance and for 1 round thereafter. This is a sense-dependent, mind-affecting effect. A flayer leech can move toward a fascinated creature, enter its space, and attempt an attach attack without ending the condition. However, if the flayer leech attempts to bite a fascinated creature, the condition ends as normal.</p>
