Foul Infusion

Once per turn, at the start of either your Charge
phase or the Fight phase, you can select one
friendly Core unit within 6" of
this model. Until the start of your next Command phase, each time a model in that unit makes a
melee attack with a Plague Weapon, an
unmodified wound roll of 6 inflicts 1 mortal
wound on the target in addition to any normal
damage. Each unit can only be selected for this
ability once per turn.
