Thanks for the responses! The problem is that I am returning with everything I need for the Master's Tools quests, and I don't have the option of talking my way through the fight, because my stats aren't high enough in the required areas to afford dialogue options, and my remaining dialogue choice all end up with a fight (that I don't know how to win.)
My party composition= Eder, Aloth, Durance, the Chanter guy (forgot his name) + my barbarian and my rogue.
