Grim Last Stand

You can reveal this order at the start of your combat phase. If you do so, you can pick 1 friendly CoS DUARDIN unit that is within 3"of the HERO with this order. Until the end of that phase, each time a model from that unit is slain by an attack made with a melee weapon, you can pick 1 enemy unit within 3" of that model's unit and roll a dice. On a 5+, that enemy unit suffers 1 mortal wound.
