Use this Stratagem in the Fight phase, when a unit from your army that contains any ACID MAW models is selected to fight. Select one enemy unit within Engagement Range of that unit. For each ACID MAW INFANTRY model in that unit that is within Engagement Range of that enemy unit, roll one D6, or three D6 if that model has the MONSTER keyword; for each 3+, that enemy unit suffers 1 mortal wound (to a maximum of 6 mortal wounds).
