Ironjaw (3.5e Equipment)

The ironjaw is a specially fitted weapon designed to go into the mouth of a creature with a bite attack. Effectively metal dentures, they enhance their biting ability and allows the creature to enhance the ironjaw, and subsequently their bite attack. The ironjaw counts as both a manufactured and a natural weapon. The ironjaw deals as much damage as the creature's bite attack one size larger, with a 20/x4 critical.

Ironjaws need to be custom fitted to a creature, provoking a -2 penalty on attack rolls and 20% arcane spell failure for using an ironjaw not adjusted to your mouth. Donning an ironjaw takes as much time as donning breastplate, and has the same consequences for sleeping with the ironjaw equipped. However, the ironjaw cannot be disarmed or sundered while properly worn.

Donning an ironjaw rapidly has a -2 penalty on attack rolls (which stacks with not being fitted for the creature).
