I left for a 3 week holiday with no WiFi and no iPad the day this started. I?m now up to part 2. I?m just reading about the study circle. However as it is now well into the event, it is of course no longer in featured and I can?t see where to buy it. Is it still worthwhile buying it by someone who thinks very carefully before spending gems as I don?t buy any? Are the drops guaranteed? Getting so tired of the wasted energy trying to trigger fangbeasts (love the description of endangered someone gave them) and the sparkling mines that don?t drop compasses. Any advice welcome.
