BLESSED BOLTS

Use this Stratagem in your Shooting phase, when
an ADEPTA SORORITAS unit from your army
is selected to shoot. Until the end of the phase,
each time an attack is made with an
artificer-crafted storm bolter by a model in that
unit, on an unmodified hit roll of 6, the target
suffers 2 mortal wounds and the attack sequence
ends (a maximum of 6 mortal wounds can be
inflicted per phase via this Stratagem).
