Welcome to Librarium Online!
So I'm thinking of going up to 1000 points and here is what I'm thinking of trying.
Flyrant with sything talons, devourerer, Warp field, TS
8 spineguants with WoN
2, 7man 'stealer squads, with EC, FT, Scuttlers
168 points each
dakkafex, 2 devourerers, ES, EC, reinforced chitin
4x warriors, ES, TL Deathspitters, TS, EC
I'm currently working mainly from the battle force and an extra tyrant, but I want to upgrade my army. As this is friendly going a few points over is OK.
Any help would be appreciated.
Here is the possible set-up you could give your broodlord:
Extended Carapace, Toxin Sacs, Feeder Tendrils
That would put you 1pt over as long as you don't change the Tyrant and I think the change don't make the list any weaker while adding a Broodlord will give you another powerful option. Hope that gives you something to think about, goodluck!
