I have the tree branch (both) plus the bottle of wine (although the bottle of wine quest won't complete) and I was given the book of summoning (although it's not in my inventory) but when I talk to Corinna nothing happens. What am I doing wrong.
Also why won't the wine quest finalise after handing in the cart burner (can't remember his name)? I have even tried selling the wine to Pierce then buying it back and trying all dialogue options to no avail. Looks like I will have 2 quests that can't be solves.
