The collar of the fine new cloak suddenly reveals a set of jagged teeth as you realize that it is a carnivorous creature, and you are wearing it.

A mawler can assume the general shape of any object that is roughly Tiny sized. A mawler's body is fleshy and pliable, but it can alter the rigidity of its body to resemble metal, wood, and even stone. Most mawlers have found that taking on the shape of articles of clothing provides the most ready meals. The ruse can be detected by a Perception check opposed by the mawler's Disguise skill.
A mawler that scores a critical hit with its bite attack while being worn severs the extremity that was inside it at the time. For example, a mawler being worn as a boot that scores a critical hit, severs the victim's leg. A mawler can only use its vorpal bite while being worn.
A creature that loses a limb suffers a -4 penalty to skill checks that require the use of two limbs. For example, a victim that loses a hand or arm suffers a -4 penalty to Climb checks, Disable Device checks, and so forth. Additionally, a creature that loses its primary weapon-wielding arm or hand suffers a -6 penalty when wielding a weapon in its offhand. A creature with the Two-Weapon Fighting feat that loses its primary arm or hand ignores the penalty for wielding a weapon in its offhand.
If the victim loses a foot or leg, the penalty applies to Acrobatics checks and the like. Additionally, the creature's speed is reduced to one-quarter. If the severed extremity happens to be the head, the victim dies immediately (unless it can live without its head).
