Can be a wizard and use Nurgle or Death
Can have one of three different locusts giving the Plaguebearers either poison on 5+, extra s4 hit when hitting with poison or giving the unit regeneration. Interesting to see how this works for the other heralds
Bloodletters: (up by 2 points)
Lost a point of S, but gained scaly skin 6+ and the hellblade gift (probably kb). They also have the Daemon of Khorne special rule.
Pink Horrors: (up 1 point)
Same rules except that a unit is a level 1 wizard and that they have the special rule blue horrors. As everyone else they also have their Daemonic God's special rules.
Daemonettes: (down one point)
Completely unchanged if Daemon of Slaanesh is AP.
All lesser daemons can have a banner up to 25 points.
Bloodcrushers: (down 5 points)
Are now special. Juggernaughts are as in the WoC book. The riders are now ordinary bloodletters with their 6+ scaly skin save, so they probably have the same save as before.
Flesh Hounds: (down 5 points)
-1S. Have scaly skin (6+), Collar of Khorne. Can be Ambushers for 10% of their base cost.
