Suffering and sacrifice

Use this Stratagem in the Fight phase. Select one ADEPTA SORORITAS WARLORD, SAINT POTENTIA or LIVING SAINT unit from your
army (excluding VEHICLE units): until the end
of the phase, that unit is known as your Suffering
unit. Until the end of the phase, each time an
enemy unit is selected to fight, if a model in that
enemy unit is within Engagement Range of your
Suffering unit when your opponent is selecting
targets for its attacks, those attacks can only target
your Suffering unit.
