Yes, I have Level 3 of both Witch and Bazaar. I'm actually pretty far in the game. In the Go Adventuring screen, the only quests I currently have available are Here Be Dragons and Snakes? SNAAAKES! I have unlocked most dungeons, as far as I know. I have not unlocked several character classes. The only "special" class that I have is the Tinker. I am also still missing Binlor Ironshield. However, I'm not sure how those things would affect a silver Blood Mage challenge, though.
