Spiteful Endurance

Use this Stratagem in any phase, when an IRON WARRIORS HERETIC ASTARTES model
from your army would lose a wound as the result
of a mortal wound.
•Until the end of the phase, each time that
model or any other HERETIC ASTARTES
model in its unit would lose a wound as
the result of a mortal wound, roll one D6:
on a 5+, that wound is not lost.
