And what about the Pantaloons enigma? I read about it, but don't know what's the reward if I complete that quest (do you know?). I guess that's really hard, especially that it starts back in BG I. I don't think many players found that out for the first time! Just think about the beginners: for those who play BG for the first time it's quite a challenge even to complete the main quests, they have no experience to look for hidden treasures and stuff. Maybe it would be the best to hide some easy to gain, bit more powerful items and hide much better weapons that are harder to find, so that both beginners and experienced players would find treasure hunting challenging
BTW, are there really powerful stuff hidden in IWD II?
