Suffer not the witch

Use this Stratagem in your Shooting phase, when
an ADEPTUS MINISTORUM unit from your
army is selected to shoot, or in the Fight phase,
when an ADEPTUS MINISTORUM unit from
your army is selected to fight. Until the end of
the phase, each time a model in that unit makes
an attack against a PSYKER unit, add 1 to that
attack's hit roll (if the attack is made by an
ADEPTUS MINISTORUM CHARACTER
model, add 1 to that attack's hit roll and add 1 to
that attack's wound roll).
