These guys would be the dark lords of the South, worse than the Shadow Lord himself. You thought those high-level tier 4 NMs were bad, wait till you face these days. They are in sequence, from the chick, to Chatterbox, to the fat guy, and finally, Hellraiser himself. Each of them represents a different element fused with Darkness, and they're capable of dealing out all kinds of damage. if you manage to beat these guys, the rewards would be amazing.
