Maybe something for the side in the civil war which wants to seperate from the Empire. "Each man under my command owes me ONE. HUNDRED. Legionary scalps. And I want my scalps!"
Ok serious mode now. Wouldn't a head make more sense? If you were sent to kill a insanly powerful bandit/necromancer/whatever and bring back his scalp, couldn't you technically just kill a random person, bring back their scalp, then lie?
