ART: Hammers of Augury

These potent tools of divination orbit their bearer, lashing out at nearby foes.
At the end of the combat phase, you can
pick 1 enemy unit within 3" of the bearer
and roll a dice. On a 3+, that unit suffers 1
mortal wound and you can roll another dice.
On a 4+, that unit suffers 1 extra mortal
wound.
