I'll place people in the most advantageous place I can find. I assume Terrus will take point going through. Lorenn can open the door, but hide behind the door itself - it opens inward. Others can hide behind the corners or behind Terrus.
Just a heads up I leave on Monday for a week long road trip. I don't know if/when I will have internet access so NPC Drako as needed if I don't respond timely.
Don't heal the wizard until you stripped her of the wand (arcane focus) and component pouch. And tied her hands. And SnorLoska can ready a whack to the head if it looks as if she's about to cast a spell!
