Alright I'm new here, and this is my first post. I don't want to take credit for this as I definitely did not find it, but this is a nice little guide to farming DM West.
It works best with a warlock so you can banish the trees and such, but anyways I think it can be done with most classes. Casters being the easiest.
What you do is time it right and run towards the first big tree boss in DM West. You should see him at the bottom of a ramp. From there, stand like 3/4 of the way down the ramp on one of the sides, near the ledges. After that, you pull a mob, when it gets near you, hop slightly down and towards the ledge. This will allow you to jump up onto the ledge. The mob will then run all the way down the ramp and then go up it at the end and up towards you. You then jump down onto the ramp again and continue to cast spells on it or do whatever. This is a nice little trick for farming sometimes EQ, Living Essences, Librams and Gold.
