Congratulations, I know how hard this guy can be...and with that, if you would allow me to go into my own experience with him...
A long time ago, in a galaxy far far...no wait, that's not right. *ahem*
Anyway, I was determined to cap every single skill on my necro, and didn't expect this one to be so daunting...boy did that change. One other necro and I picked up a pug in Rankor and set out for Dreadnaught's Drifts. Near the end of Snake Dance, however, mobs of trolls set upon us. Frustrated, the rest of the group ditched us. So through sheer determination, that other necro and I made it to Dreadnaught's. Once we got there we already had considerable DP (probably 60% already) and couldn't really take down anything, so the strategy basically consisted of pulling enemies to the spawn point and wearing them down. Then we got to the wurm...Immediately it pops out and kills the other necro in short order. So I, a relatively inexperienced N/Mo, was left to solo this thing. Fun. About 5 or 10 minutes later though, the thing finally died. Man, did I love blood magic after that. Plus, not much beats that feeling of accomplishment. I resed the necro, we both capped FoC, and got the heck out of there.
Sorry to take attention of the thread away from you, I just wanted to share my story.
