Blood Boil

Pick a friendly Blades of Khorne Priest to chant this prayer, pick a visible enemy unit within 18" of them to be the target, then make a chanting roll of D6.

Roll a number of dice equal to the number of models in the target unit. For each 5+, inflict 1 mortal damage on the target. In addition, if the chanting roll was 8+, subtract 1 from wound rolls for the target until the start of your next turn.
