Ring of Iron Skin

The Ring of Iron Skin provides +3 protection against weapons. It can be found in multiple locations: near the stairs at Akil's Farm by turning left under a tree, as a reward from Cassia for collecting blood chalices, at the pass near the orcs by a fireplace, in a forest cave in the Valley of Mines near Den's body, inside Greg's hut at the pirate camp inside a wolf head, and purchased from Erol starting in Chapter 1.
