Looking for a Deep Gnome Warlock build for three ITRs

[lord_of_rage]

I'm looking for a fun Warlock build to get the three Deep Gnome Warlock lives knocked out for the MRR. I've got 4 racial points, the wiz past life, and full +7 tomes. Something that is comfortable in low skull reaper. I tend to solo most of the time. Type of Warlock doesn't matter. With three lives to do I'll most likely try more than one suggestion. I appreciate all the help. Cheers. I'm using hearts, so I'll be 20 Warlock.
