Shadowbolt, haunt, corruption, UA, CoA, shadowbolt filler until 25% when it becomes drain soul filler. When you get the life tap glyph you want to put a rank 1 life tap before the first haunt to get the bonus. Since curse of the elements is no longer improved with Malediction I think it's best if deep destruction Locks put it up as Affliction locks get a boost to CoA and demonology locks use CoA for Molten core procs.
