Iron God of War

Iron Yojutsu: Iron God of War (鉄妖術『鐵ノ武神』) is an Iron Magic spell.

Description
The user transforms their body into iron, including their clothes. Armor-like ridges and protrusions also form from their skin and clothes: a crest and forehead plate from their forehead and eyebrow ridge, a circle of three magatama on the sternum, shoulder and forearm guards.

This iron is incredibly strong and is capable of withstanding piercing Ice Magic spells from a Paladin. Despite their body being made of iron, their mobility is not inhibited.
