For the Blood God!

When: Fight phase, just after a World Eaters
unit from your army destroys an enemy Unit.
Target: That World Eaters unit.
Effect: Make a Blessings of Khorne (BoK) roll.
You can use the results of this roll to activate
one BoK. That BoK does not count toward
your maximum number of activated BoK, but
all other rules for BoK apply.
