Happy to say I've tested out the forge and finally got my hands on an Augur of the deep my BG desperately needs Now to get those mushrooms!
Got me a pair of Soulthirsters...always was a fan of the rune (even when not actually playing), and now I can finally try them out. Sacrificed all my Shattered Peaks to do so. I bet the demons liked my offering. ^_^ Also, the forge needs a "sacrifice all" button. Extracting commons one by one is irritating.
