Special Abilities
Berserk (Ex) When an ironwife enters combat, there is a cumulative 2% chance each round that its bound spirit within it breaks free and the ironwife goes berserk. The unbond construct runs amok and attacks the nearest living creature or smashing some object smaller than itself if no creature is within reach, then moving on to spread more destruction. The maiden’s master, if within 100 feet, can try to regain control by speaking firmly, persuasively, or threateningly to the construct, which requires a successful Charisma check (DC 15). It takes 30 seconds of rest by the maiden to reset its berserk chance to 0%.
Impale (Ex) A transformed ironwife deals 3d4+7 points of damage on a combat maneuver check when grappling or being grappled.
Spikeskin (Ex) As a move action, the ironwife can transform to reveal a multiple of spikes and blades about her body. When in this form she has 2 claw attacks as listed above, and the ironwife’s reach is improved to 10 ft. She transforms into this form as a free action when berserk.

Ironwives are constructs infused with the soul of a loyal guardian whose mortal time has passed. They are female in form and as they are intelligent. They accompany their master everywhere to ensure their safety.
