Beheading is something I miss on CF, and altho you can get the head to occasionally fall off when you kill a mob/PC, how about the following..

Let disembowel randomly pick either the head, or the abdomen for slashing. The name would probably be in need of changing, but I see a nifty little echo opportunity. Decapitariationserationment, as Valg would put it.

Obviously this wouldn't appeal to certain people who insist on playing nothing but mages, invokers mostly, but hey, screw mages.

Also, I don't recall ever seeing the new bleeding effects working off disembowel, any plans to add bleeding to that too, when it fails and just gives some dam?
