Some alternatives. These will reap better cash than the ones listed. Having just comeback money is important to my toons.

11-12 Blackburrow Bottom of ramp (level 3 per Wiki) ZEM + gnoll fangs = quick xp.
12-13 Western Karana Bandits east of Misty Storyswapper (#3 on wiki map) non-evil toons can turn in bandit sashes for additional xp and a bronze weapon

Very adventure friendly suggestions thanks, many gaps in leveling still open. More suggestions welcome.

This is an awesome guide, thanks for making this. Looking forward to it's completion.

I have an alternate progression which doesn't require much travel between the zones, particularly in the earlier levels when travel is more dangerous and difficult. Once you get to 35+, travel is easier and so the gaps become larger. Many of these are probably not ideal, but I'm pretty sure they're all doable with a solid soloer or a decent duo/trio. Certainly some will be slow.

^^ CT would be pretty hard at level 22 i would think. otherwise looks solid.

Bump due to the increase in players lately and i.creased baby alts looking for a diferent experience. This sounds like a great idea

If you roll Neutral/Evil Erudite don't immediately run to QHills! Stay and hunt Kobolds for their 'Useless Cloth Cap'. Turn them in at the skeletons guarding Paineel and rake in the cash. Aside from decent exp return you get a gem for each turn in, quick easy plat (have been getting all sorts of gems, some worth 12pp+). You can use this method to get up to 6-7 quickly and have plenty of plat for spells.

great guide!

I'm currently using this guide to level Feanoir, and I'm level 13 in WK, if anyone wants to join in the more the merrier!

I've been doing this solo but I know that with a duo it'd be even better:
11-12 Steamfont Mountains (Near windmills and minotaur caves)

Only downside is the earth elementals being immune to non-magic weapons but I'm a necro so meh. This is great to go from Crushbone to Steamfont and still get decent exp. Not heavily camped either; not seen a single soul. :3
