Heart of Iron is a legendary chest armor in Diablo III. It requires character level 8 to drop.

Prior to Patch 2.1, it was the only Chest Armor with the Life on Hit guaranteed roll.

As of 2.4, it also gained a unique affix that increases Thorns by a percentage of the Nephalem's Vitality. Thus, it is specifically designed for Thorns builds, particularly Crusaders. Combined with Thorns of the Invoker, this can quite literally turn the health of the bearer into a deadly weapon.
