Have you completed the quest yet (or just the fourth sub-quest)? (Rhetorical, because that's the reason.)
Hey rowley was just wondering do dummies like slayer/agility/hunter and the combat ones have a chance to drop a shard?
I have no idea, that's a question more for Mod Campfire, I'd say. I would assume if proteans work, dummies also work. Can anyone else in here confirm?
