Am I hunting in the right place? Obsidian Shard Mountains, Obsidian Gargoyles down in the southwest corner? For the Blackstone Gem (shaman starfall quest item)? I've been here for, literally, an entire level. I came as soon as I dinged 33 and I just hit 34 hunting absolutely nothing but obsidian gargs. I've seen 17 slabs and 12 eyes for the shadowknight quests drop, but not a single Gem.
