2. once you head toward the Lanilor's house, an old lady should attack you. mabey she dropped the key. or it is in the house.
The key should be straight into Lanilor's house, on the shelf with a plant and banner. Try hitting the alt key.
The witch didn't drop the key and the key is not inside the house, on the shelf or otherwise. It must a bug. (I'll check out the link you provided.)
3. the bottle should be in the room Anthrabert was in.
If the exquisite wine bottle is not in Anthrabert's room, Corinna will accept regular wine as well.
Drat! I remember drinking an exquisite wine way back when I first visited this town. This was way before the quest. I did not know it was a quest item! I'll try using another wine bottle (with my luck, I doubt it'll work).
Thank-you both for replying! =)
New Question:1. Is there anyway to complete the 'Do I want to Summon a Demon' quest without failing it? When we summon the demon, it spawns "out of control" and kills the female, then proceeds to attack me. When I slay the demon, the quest automatically shows up as failed. Is it because I didn't use the exquisite wine (and instead, used whatever wine I had on me)?
