WILD FURY

Use this Stratagem in the Fight phase, when you
select a WORLD EATERS unit from your army
to fight with. Until the end of that phase,
improve the Armour Penetration characteristic of
melee weapons models in that unit are equipped
with by 1 (e.g. AP 0 becomes AP -1).
Sheer aggression can cut through even the thickest
armour.
