Invigorated by Evisceration

Use this Stratagem after an enemy unit is
destroyed as a result of a melee attack made
by a model in a CULT OF STRIFE INFANTRY
or CULT OF STRIFE BIKER unit from your
army. Until the start of your next turn, models
in that unit have a 4+ invulnerable save.
The Cult of Strife welcome the attentions of enemy
combatants, and by feeding upon the death throes of
their victims they are never short of the vigour required
to remain front and centre on the stage of battle.
