This is gettin to be somewhat wide spread knowlege ive been doing it for awhile now. So figure i might as well share something with you all. First you need a mage specced for improved dampen magic, and the talent that gives you mana on a successful full resist is also good for doing this, i get about 300-400 mana per resist so if with mage armor and this talent you get 25 all resists right off the bat...get one of them crafted 30 nature resist cloaks and enchant it with +all resists or +NR and you should be laughing. This isnt necessary but it helps to make it so you have no downtime. Anyway what you do is goto Silithus, buff up mage armor, dampen magic etc...and goto the Dust stormers set up AE rank 1, and run through the stormers and keep rank 1 AE'n...this is to hold agro...train as many as you can onto you and then simply AE them down however you like. You will only take 1 damage per hit from each one so you can get like 10-20 fairly easily. But its getting to be a pretty popular place so late at night is best time to do this. There is an East Side and a West Side of the mountain they spawn in each place. So clear 1 side run and check the other. In a few hours time i was able to get about 16 essence of airs and well over 200 core of elements, and countless greens. It gets boring fast but hey its EZ MODE MONEY GG
