This book is more difficult than book #1. However, it is not impossible. Just really hard. I didnt have too many problems reaching the end. The larger challenge is to limit the number of battles you get in so that you still have HP left for the obscenely hard boss battles at the end. Hint: play smart, not hack-n-slash.
Thanks for another great game book,TMG.
