Cowardly Grots! If a unit of Killa Kans suffers 25% or more casualties during any one phase, the unit must roll a D6 at the end of that phase. Add +1 to the dice roll if there are three or more Killa Kans in the unit, and a further +1 if there are one or more Deff Dreads within 6" of the unit. On a result of 3+ the test is passed and nothing happens. On a result of 1-2 the test is failed and every model in the unit immediately suffers a Crew Shaken result. Note that no models lose a Hull Point as a result of a failed Cowardly Grots! test
