I disagree. I think Aura is more usefull. Lots of CC squads, which your Daemon Prince will see, have power weapons. Without that invunlerable save he will be taking wounds pretty often and he'll eventually die against any decent squad's with power weapons.I would ALWAYS take feel no pain on a khorn statured prince, as it gives you an additional 4+ save against all ranged weapons that are less then STR 10. Las cannons, bright lances, rending assualt cannon hits, etc all get a 4+ feel no pain save. It really makes sure this monster gets into CC, or if he dosn't he soacks so much fire the rest of your army should.
Or some squads have hidden powerfists. If they get up to strength 10 then it will instant kill your lord. Of course it isn't that common that a powerfist will get up to strength 10, but their are units out there that have Strength 5 with powerfists.
I'd take off Daemonic Possession off your preds and add side sponser lascannon's. This will cost 10 more points all together but you could take essence off yoru lord for this.1 Chaos Predator (Heavy Support) @ 145 Pts
