Flay Them Alive

Use this Stratagem in the Fight phase, when an
enemy unit is destroyed as a result of an attack
made by a NIGHT LORDS model from your
army. Until the end of the turn, when a Morale
test is taken for an enemy unit within 12" of
that NIGHT LORDS unit, your opponent must
roll one additional D6 and you can chose one of
those dice to be discarded.
Death does not always follow defeat.
