These are formed out of carbon-based chitin with a monomolecular edge attached to lengths of exceptionally tough muscle fibre situated between a creature's ribs. The hooks are fired by a sharp, intercostal muscle spasm, shooting out to allow the creature to snare its victims from a distance. The flesh hooks are also sometimes used as grapnels to allow creatures to scale vertical surfaces at great speed.
A creature with flesh hooks counts as being equipped with frag grenades in close combat. In addition, creatures with flesh hooks count 'vertically impassable' pieces of terrain such as high walls or cliffs as difficult terrain.
