If life hands you lemons, make lemonade.
If life puts you in charge of defending a gold mining operation and you are only a mage....well
During battle/war the heads of all slain are decapitated and collected by the slayer. The slayer will clean them up and put them on display for inspection by the commander. Depending on the deads name, rank, and expression on the face held by the death blow-the slayer will be rewarded by gold and/or status.
