Solo Undead Levelling Guide Project- Go!

[Reneb]

So I feel like we should get a compendium up for this type of thing. I see the question every now and then and have yet to see a good answer. I'm going to contribute where I am at, and hopefully see some variety in responses.

1-5 decaying skellies
5-10 pillar in nektulos
10-20 Kurn's
20+ Is where I'm not sure on anymore. I know that unrest is viable, and I have been meaning to check out LOIO to see if any of the ruins are around level 20. Any kunark zones for the 20-50 would be greatly appreciated.
