Necro Kinetics, abuse repel with KB to KD IO and Force feed back procs, siphon speed for boost haste further and hasten to bring you soul extraction to almost perma with ease. Ohh and fast pets. For ease of buffing make a macro like
/macroimage "Gadgets_Turret" "Petboost" "petselectname DumbLich$$powexec_name speed boost"
And go ham >:)
Bonus tip: Theft of Essence: Chance for +Endurance for help with end. You can also use it in Twilight Grasp in dark Miasma so dark works fine too, but I hate slow pets.
