Vengence for Isstvan 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.
