Well I was asked how I'd run the shooty demons, but truthfully...I think demons are just fundamentally screwed in 5th. Specifically, tzeentch troops.
I figured out why I was doing so poorly against them, I had a torrent army without any blasts.
Once I put a few in...holy moly did I make tzeentch shooty armies go away.
Normally I do torrents or blasts, not both in the same army. Lesson learned.
Give up on shooting. Anytime you fail that 3+, you'll almost always lose as the wrong set of guys come in.
Also, how to make a Chaos Demon army, AND make one that you can actually use in both Fantasy AND
40k.
Man, so many different requests.
So, how would I run a Chaos demon army now that it's been out a while?
Well not sure I can meet all the requests, but I will give it a shot.
40K Core:
Skulltaker, Juggernaut.
Herald of Khorne, Juggernaut.
2x Plaguebearers, 15 strong.
2x8 Bloodcrushers of Khorne, Icon, Fury, Instrument.
That's 1500 points (roughly).
To get to 2000 points, I'd say add whatever you want.
Preferably something that can deal with Land Raiders.
I'd personally suggest 3 soulgrinders and 3 units of screamers to flush the army out.
Here's the fantasy list:
