I have the lexicon and have been through Avanchnzel a couple of times, but obviously not gotten where I'm supposed to be. At the moment I'm halted on the balcony (yep, found the treasure chest) but where do I go from here? I know this has been discussed, and I've searched around, but found nothing that helps me.
Any help at all will be greatly appreciated. (Just as an aside, I think Avanchnzel itself is beautifully designed.)
