Implant attack

Some bio-weapons seed their victims with a lethal
spore-cyst. This bloated parasite rapidly expands and
bursts, tearing the unfortunate host apart in an
eruption of gore.
Use this Stratagem after a TYRANIDS unit from
your army fights in the Fight phase. Roll a dice
for each enemy model (other than a VEHICLE)
that was wounded by any of this unit’s attacks
and not slain. On a 2+ the model suffers a mortal
wound.
