before to read and use that guide, I'd like to tell you that if you didnt know how to do the 2M quest, troll quest, all the hidden honour quest, then after reading that guide you'll know, BUT you'll never be proud to have discovered the quest by yourself, you'll never have the fun of exploring the dungeon to find everything you missed, you'll just accept the fact that you are too noob to do it by yourself... i let you think about that before reading and using it...
For the other one who think that they know everything in b2f, well maybe you don't, so you should maybe read it...and I think there are still things that we don't know about b2f, too much trigger never used...
