Some creatures are so large or disturbing that they provoke an irrational fear in the foe.
A unit containing one or more Fear-causing model gains +1 to their. If the of all Fear-causing models is double or more, the Combat Resolution bonus is increased to +2. Note that the bonus from Fear is otherwise not cumulative for having multiple units with the Fear special rule involved in the same combat.
If the majority of the models in a unit cause Fear, they also gain the(Fear) special rule (described later), and thus the Combat Resolution bonus is ignored for that unit.
