No, killerTeddy, i haven't seen any walkthrough like that, but i've also found party make-up to be as important as level; if you can protect yourself from magic well, there's no reason you can't go everywhere as of about L15 in Normal, but, for example, if you don't have Element Shield there are some things that'll hurt you a lot in Mountain Wilderness with Acid, Poison and Fire attacks. There's a lot of variation like that, so it would take a lot of text to map out 'comfort zones'.

Ive considered collating a biestary, but that involves too much work trying to work out exp given...

Actually if you have already killed monsters of that type or have enough mythology then rightclicking on monsters will tell you amongst other things the xp they give.

oh yeah i know that. If i did do this i would hack the character so it had 125 mythology then slowly progress through the game.... visiting lots of area's at level 1-5, then going back 5-10 then 10-15 etc.
Find as many critters as possible.

Ive noticed though even with superhigh mythology it doesnt tell u the EXP they give untill you have at leastkilled one of em.

Kinda gets hard to calculate with multiple different guys in combat. (unless u fingt them again later).
