KingFriday: Thanks for the tips & no spoilers.
I got to the point you mention, and certainly have less worries about juggling items now.
Inventory bloat is handled quite nicely as you progress, actually. They even go so far as to provide a key ring at one of the shops; I'm starting to feel like the janitor of Arx now. :)
Great, glad I could help... Arx is a great game. Don't be afraid to access a tip or hint from time to time from 'gamefaqs.com'. There's also an old *great* Arx guide from years ago in PDF form with pics of all the maps for all the levels with a complete walkthru. I *don't* usually use these types of guides often, but I find for *me* at least, that Arx can be a difficult game to know 'where to go next'... Even after finishing it once years ago, I still have to consult a guide once in a while. And I don't care. Keeps me from getting frustrated, and at my age (I'm what you might call an 'old timer'), I don't need any more hassles. Just don't overdue it with guides or they can ruin the (any) game. If you can't find the PDF file and you really want it (It seems that it's hard to find since Rpgdot went belly up), go over to ttlg.com (a homage to the great 'Looking Glass' games + others that are similar), and there is even a thread there on the subject. Let me know if you need any help. And good luck... :)
