Force Field Boosta

Use this Stratagem at the start of your opponent
Shooting phase. Select one model in your army
that is equipped with a KFF. Until the end of the
turn, replace that KFF ability with the following:
•(Aura) While a friendly ORKS unit is within
9" of the bearer, models in that unit have a 5+
invulnerable save.•
At the end of this turn, the KFF overloads and
cannot be used for the rest of the battle.
You can only use this Stratagem once per battle.
