HERO OF THE CHAPTER

Use this Stratagem before the battle, when you
are mustering your army, if your WARLORD
has the ADEPTUS ASTARTES keyword. Select
one ADEPTUS ASTARTES CHARACTER
model from your army and determine one War-
lord Trait for it; that model it is only regarded as
your WARLORD for the purposes of that
Warlord Trait. You can only use this Stratagem
once, unless you are playing a Strike Force battle
(you can use twice) or an Onslaught battle (you
can use three times).
