1750 Duke/Coven/cult list

HQ

The Duke Sliscus

2 Heamonculi with WWP and venom blades

Elites

4 trueborn + Blasters in Venom with SC

3 trueborn + Blaster in Venom with SC

Troops

2x 9 Wracks + Liquifier in Raider + flicker

3x 10 wyches + Shardnet/impaler, Hydra Gauntlets, Haywire Grenades, Hekatrix, Agoniser

Heavy Support

2x Talos + additional close combat weapon, Chain flails

The list is semi-competitive, expect to be facing orks, chaos, grey knights, smurfs, imperial guard.

All you're getting from the Duke is the drug re-rlls with the Wyches...at that stage why not just go hog wild with Wyches and sack the Wracks? You can just have the Haems be suicide Haems and then have more Wyches you're boosting via the Duke.

Agree, but if you really wanna use the Duke (I use him often) then make sure to put in some warriors or trueborn with carbines to take advantage of the extra poison. I have found 20 warriors with 2 splinter cannons work very nicely. By no means allow this unit to be assaulted!
