Hey there!
So this is my list for the new Chaos Daemons:

Keeper of Secrets (soporific musk; transfixing gaze; unholy might) - 245

3 Fiends of Slaanesh - 90
3 Flamers of Tzeentch - 105
3 Flamers of Tzeentch - 105

10 Plaguebearers ( chaos icon) - 175
10 Plaguebearers - 150
10 Bloodletters - 160
10 Bloodletters - 160

Daemon Prince (daemonic flight; iron hide; cloud of flies; noxious touch) - 155
Daemon Prince (daemonic flight; iron hide; cloud of flies; noxious touch) - 155

1500 pts with 52 models. I played today with it for the first time against Necrons and by the 4 turn they phased out, so I can say I'm pretty happy with it so far, but I would still like to know what you guys think about it, C&C welcome

I like this list. Its quite similar to one of my own. It appears your points are a little off though. The fiends are undercosted as are your princes. Also remember that you cant gift your princes with noxious touch and cloud of fllies unless they have the mark of nurgle. Other than that a nice list.

Fourteen out.

Underpriced? How much does one costs then? because I'm looking into my book and the points are right...about the Princes you're right, they cost 215 points each so my counts are a "bit" of, I have to review the list then....so any ideias to cut of the points?
