General Information
Iron Flesh comes with 3 casts per attunement slot and has a duration of 30 seconds. During this time, the player becomes metallic and recieves greatly increased physical and fire defense; however, their movement speed is greatly decreased (reducing their mobility to the point where it's as if they're past 100% their endurance level).

Overview
Pre-patch 1.05, Iron Flesh was immensely powerful and popular for taking down bosses such as the Four Kings and Gwyn, Lord of Cinder. However, it has since been nerfed drastically and is no longer very effective, drastically decreasing the practicality of using it.

Iron Flesh is almost never used in PvP, as the increased defense rarely, if ever, justifies the massive movement penalty.
