Chest Trap

Chest trap [minor] by Iczer

'looky looky looky. I got you right where I want you'

The character can grow a set of 'jaws' on his torso, which he may use to attack others, or simply grapple with others.
These jaws, which typically open vertically, cannot swallow, but can chew. If open, the character can attempt to grapple with an incoming attack. The character attempts a grapple rather than a parry, using half his normal strike bonus. If successful, the attack inflicts half damage, but the offending limb or weapon is clamped in between powerful Jaws. A fail simply means the character did not manage to clamp the jaws shut in time. he takes the hit and has no option to use an auto defense (but may use a regular dodge if he desires, and may roll if able.
While activated but closed, the Ribcage is effectively armored, granting the character a natural AR of 11 (though called shots to the head or limbs ignore this AR).
When grappling, the character may engage the Jaws to assist (adds +4 to grapple checks.
If a target is caught in the Jaws, the character may expend an action to chem with those jaws, inflicting 2d6 damage, plus a bonus equal to his PE bonus (treat his PE score as an equivalent PS score).
The chest Jaws cannot swallow. The jaws may be retracted at will.
