Rune of Wrath and Ruin

If answered, pick 1 enemy unit within range and visible to the chanter. Roll 6 dice. For each roll of 5+, that enemy unit suffers 1 mortal wound. In addition, if a unit suffers 3 or more mortal wounds when this prayer is answered, that unit is ruined until the start of your next hero phase. While a unit is ruined, ignore positive modifiers to save rolls for attacks that target that unit.
