Wrath of the Wronged

Use this Stratagem in your Shooting phase,
when an ARCANA ASTARTES INFANTRY
unit from your army is selected to shoot, or in
the Fight phase, when ARCANA ASTARTES
INFANTRY unit from your army is selected
to fight. Until the end of the phase, each time
a model in that unit makes and attack, add 1
to that attack's wound roll.
