Look, I'm not about t' play games with ye. The Scarlet Crusade's Crimson Hammersmith was nothin' worth mentionin' before, but now that they're Balnazzar's Risen, the damned dreadlord has taught him t' make all sorts of powerful demonic weaponry.
It's simple. Find their blacksmithing plans and kill the Risen Hammersmith when he comes for 'em, so that we can make sure their army doesn't get their hands on demon armaments. They're powerful enough as it is!
