Kings of War Ratkin Shock Troops Upgrade

Only the toughest warriors of the Ratkin become Shock Troops. Such elevation is not awarded, but claimed through blood and combat. Should a warrior kill one of the shock troopers, they inherit the weapons and authority of their station without question - for only a weakling would allow themselves to be killed by their lesser kin. As one final insult, the skull of the defeated is picked clean and fashioned into a helm, which is worn into battle by their successor. This brutal practice keeps the ranks of the Shock Troops strong and utterly ruthless.
