Didn't X reanimate the barghest? What does he know about the 'stones?
Also, does anyone have the ability to cast Desecrate, preferably on some kind of altar? Just covering my bases in case RJ croaks it and needs to be ghoulified.
(Some way of grabbing Corpsecrafter and Nimble Bones, even temporarily, would also be cool, although RAW they don't work on necromancy feats.)
