Forgefiends and HelDrakes have it will not die
Typhus has FNP
If Typhus rolls a 1 on his daemon weapon he is allowed to take an Invuln save and a FNP but is reduced to weapon skill 1
Forgefiends and Maulerfiends ignore stunned on a 2+
This was G4 and I finally did not get tabled or lose, so I am happy with the result
I think I am starting to find a build that suits me for maximum performance as I am concerned
I am looking forward to the next round in the campaign
