Tested a verison of this out last night vs my mate and changed it up a bit.
I know fellblade is not 'competitive' but i own one and its fun. I was killing two russ's a turn with it.
Idea is one
DP stays with it, gives it +1 to hit and re-rolls so its hitting on 2's re-rolling 1's

and also gives it -1 to hit it.
Other
DP goes with the spawn as a distraction bit of a healing
DP to keep them going
smaller cultist unit obj hang
bit cultist unit -1 to hit alpah legion, sorcerer gives them the 5+
fnp they maybe inf do vets of the long war, come back again with tide of traitors all that annoying cultist blob stuff.
FR goes on anti infantry patrol
