The main rule of the codex is "Blood for the blood good":
You get "blood points for every unit you destroy and for every unit you are destroyed. Carachters slained in challenges generate blood points as well.
At the beginning of your turn you can spend those blood points (effects lasts till the beginning of your next turn)
1 Adamantium will
2 Rage + Furious Charge
3 Feel no pain
4 +1A
5 Summon 8 bloodletters of 5 Flesh hounds
6 Summon 3 Bloodcrushers or one Skull cannon
7 One carácter becomes a Demon Prince (LD test, if failed becomes a Spawn instead)
8 One character becomes a Bloodthirster (Same as above)
Once you spend a blood points you loose them all. For example if you have 5 and spend 4 for Feel No Pain, the left point is lost.
The GW page already has the listing of the units that are in the codex, at least if they have a model.
Kharn isn't on it, neither are the Oblies nor the Mutilators, no Warpsmiths or Chaos Chaplains.
I did note that the hellbrute is on the heavy support section, that is interesting, not really good options on the heavy:
Soulgrinders, Defilers, Helbrutes, Maulerfiends, Shootyfiends, Skull cannon and the Land Raider, no predators or vindis it seems.
The rule preventing CD from joining non-CD is Daemonic Instability - it would be pretty major if the units here lack it.
All daemon units have Fearless, instead of Instability.
So can you confirm that daemonic characters can join non daemonic unis (and vice versa) and whether they benefit from locus and other such rules.
Yes to both.
Deze codex lijkt echt gemaakt voor mijn leger
