Your armor has a retractable spike-covered shell reminiscent of Hwanggot's heavily armored geobukseon, or "turtle ships." The shell unfolds across your body, giving you a +4 circumstance bonus to AC and resistance 2 to bludgeoning, piercing, and slashing damage until the end of your next turn. Spiked chains propelled by small bursts of black powder also erupt from the shell, dealing 3d4 piercing,2 persistent fire damage (reflex save against your class DC) to all creatures in a 5-foot emanation.

A feat with this trait alters the construction of your innovation. If you have the reconfigure class feature, you can retrain such a feat more easily.
