Steelborn Iron body
The Steelborn Iron body is an Iron body focused on strength, used by Yerin Arelius and her master the Sage of the Endless Sword. It is described as "the best Iron body in the world for pure brute strength" on advancement to the Lord realm, allowing its user channel their madra into it to improve their physical power.[1]
It is attained by being submerged underwater for some time prior to Advancement, breathing through a reed. Like other Iron bodies, the longer the ritual is undergone, the greater its effects will be for the user; Yerin spent three days and three nights in a pool in preparation for advancement.[1]
