VENGEANCE FOR ISTVAAN V

Use this Stratagem in the Fight phase,
when a SALAMANDERS unit from
your army is chosen to fight with. Until the
end of that phase, when resolving an attack
made with a melee weapon by a model in
that unit against a WORD BEARERS,
IRON WARRIORS , NIGHT LORDS or ALPHA LEGION unit, you can re-roll
the hit roll.
