Dark Keeper Ofgut

Dark Keeper Ofgut Stonefist can be found in Blackrock Depths. He is one of six possible Keepers which spawn after a party member looks at the portrait in the Black Vault anteroom. He drops the Dark Keeper Key which is needed to open the Dark Coffer in the Black Vault. Ofgut appears amidst a group of dwarves near General Angerforge. You will need to be able to open the Shadowforge Lock to get to him.
