I just got out of Shame after an extensive exploration mission.
Makes me want to contract a set of runebooks where every level of the old dungeons (in a safe place) is marked on all levels! Some areas are hard to get to.. the wall guards are a bit worthless and hard for a mage to kill, nothing for a tamer... yet totally avoidable due to runes. hehe. I really dont remember "some" of the monsters. I know I used this dungeon a lot in my younger days... but I have no clue why or for what... or if it was good farming for something.
As I've recommended to EVERYONE that has this issue with getting stranded inside dungeons or spawn areas that are hard to reach? Keep a small stack of runebooks at your house of the most commonly traveled areas, hard to reach, only so you can access them. This works great for hunting spots as well as mining or whatever. Even a single rune inside a container (easy to see) can save yourself.
I do this... and/or to insure a stealth/mage can access the same area, waiting to take loot or rez if something goes horribly wrong. Learned too many hard lessons.
