I have a 53 enchanter and a 46 rogue, and that helped me considerably when it came to items and prices. I am a 35 druid, who started making these when I hit 188 in pottery. I had my chanter make a stack of clear mana, and 20 bars of magic clay (ack, non stackable), and I had my rogue make a stack of white lead. I was successful 60% making the unfired idols. I am still having a difficult time getting Perma Crystals and Iron Oxide, but I do have 5 finished idols ready for my friends who want them. The rest are going on the market.
