I am guessing that it is advantageous to take Prince Thrommel into the party? Or not? How does one get his sword? Also...if I take him into the party, I have to let either Elmo or Otis go. I can get Elmo back, but not Otis. But I like Elmo better than Otis. Which one should I pick? I could go ahead and just find out, I guess...but I think this is a crucial decision? Thanks for any advice.
