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.
