Inquisitor Solomon Lok (FW)

When included in an army Solomon Lok is always accompanied by an Inquisitorial Henchmen Warband. This Warband may either be deployed as a separate unit, or it may be joined by Solomon Lok as per the normal rules for characters joining units

When a unit that contains at least one model with this special rule takes Morale checks or Pinning tests, they ignore any negative Leadership modifiers. If a unit is both Fearless and Stubborn, it uses the rules for Fearless instead.

Independent characters can join other units.  They cannot, however, join units that contain vehicles or Monstrous Creatures.  They can join other Independent Characters, though, to form a powerful multi-character unit!  Independent Characters pass Look Out, Sir rolls on a 2+. A unit that contains one or more Independent Characters does not need a double 1 to Regroup if reduced to below 25% of its starting numbres, but instead tests as if it had at least 25% remaining.
