Other friendly models that can draw Line of Sight to Saruman gain a bonus of +1 to any Courage Tests they are required to take.
The Voice of Saruman
During his Activation, Saruman can use one of the following abilities instead of Casting a Magical Power. Each of these abilities can only be used once per game. Conjure Lightning – Choose a point on the battlefield at least 12" away from any friendly model (with the exception of Gríma Wormtongue). Each model within 2" of the chosen point suffers a Strength 6 hit. If a Cavalry model is affected, both the rider and Mount will suffer a Strength 6 hit. Summon Gale – Until the end of the turn, enemy models halve their Move Value. Call Thunder – Until the end of the turn, enemy models have the Fearful special rule.
Spies of Saruman
Saruman can draw Line of Sight from any friendly Crebain models on the battlefield.
