I'm not sure how much endings there are. I found three so far, apart from obvious defeat.
You can get the wand from the small secret room. For that you will have to talk to Maya at the fruit stand, then use the info provided by the wenches/barmaid to talk to the lowlifes. Trust Alex as Anthony and Dawe is lying. He'll tell you the code. (free)
You need to bring the purchased pot from the pottery. (-60p)
You need to purchase lockpicks from the blacksmith (-40p)
If you seduced cat Quinn over secrets, you will not be able to open the extra room. There's an option for any of the 4 items there.
Also if you didn't seduce Moira, you have an option to get a free mug of mead from the barkeep.
Anyway, you get the wand from the small room for which Alex gives you the correct code. --
Ending #1 If you want to escape with Princess Sage, just use the wand + lockpick + acid on the locks and it'll unlock.
I'm interested if anyone else can find more endings to it (Ice, Nadia, party win) Wtf was the crystal tip from Cathy about?)
