This is going to become a repository for maps I (and possibly others) have made to help new and veteran players alike know where the treasure is in each zone, so that gathering items and money becomes easier.
So far I have three zones, but I will update as I have more time to explore.
The maps have element of color coding on them:
Red indicates a chest that you must either fight or be invisible to reach, but nothing should obstruct your way to it. (Get those potions of invis!)
Green indicates you have to get through a locked door - meaning if you're bashing it your invisibility might be in danger.
Pink indicates a bookcase, and in some cases there may be green in it to indicate it is behind a locked door.
Blue means you are probably going to get rocked by enemies, and you should be strong enough to fight in the zone.
