Enfolding Strike

Use this Stratagem in your Movement phase,
when a PARASITE OF MORTREX model
from your army finishes a Normal Move or
Advances. Select one enemy unit that
PARASITE OF MORTREX model moved
across this phase. Roll one D6: on a 2-5, that
unit suffers D3 mortal wounds and becomes
infected with parasites (see Parasitic Infection
ability, on model's datasheet); on a 6, that unit
suffers 3 mortal wounds and becomes infected
with parasites.
