Alaitoc + Flayed Skull

Not necessarily super competitive but still fairly capable with some fun flavour. Warlord, Drazhar and Incubi take one of the Raiders.

Warlocks are 55 points now (although I think that's been taken into account already for your total?) and both your Craftworld psykers have one too many powers.

It looks like a fine list, and I've found Flayed Skull/Alaitoc to work very well together. Your Incubi and special characters seem like slight weak links but I imagine that this'll still bring a lot of pain.

I'll have to double check the prices when my book is in front of me, hopefully it's square.

I'm sad how Incubi turned out but I've converted a whack of em and it just makes me sad to see models with such great lore and flavor collect dust, even if they're not tier 1 picks.
