All Skaven, except other Skavenslaves, automatically pass Panic tests caused by friendly Skavenslaves. Also, Skaven can voluntarily target ranged attacks at enemy units engaged in close combat with Skavenslaves (but no other friendly troops). As combatants are constantly in motion, all successful hits must be randomised between the fighting units (1-3 friend, 4-6 foe). If there are multiple units, further randomise to determine exactly which one is struck.
