TALENT FOR ANNIHILATION

Use this Stratagem in your Shooting phase, when
a MEPHRIT unit from your army is selected to
shoot. Until the end of the phase, each time a
model in that unit makes an attack, an
unmodified wound roll of 6 inflicts 1 mortal
wound on the target in addition to any normal
damage (a maximum of 3 mortal wounds can be
inflicted per phase via this Stratagem).
The Mephrit seek not merely to defeat their foes, but to entirely expunge them from the face of the galaxy.
