Me and my mate love our randomly appearing creatures in games. They add so much fun and chaos to the games. In fact, we are always sad if any recovered treasures don't result in newly appearing ones. But creatures can also really screw over one player. In our games it's becoming a running gag my mate gets all the creatures on his side of the table, making games way harder for him. So I thought, why not reward players who kill them?
I can see warbands taking back fresh boar meat, venom sacks from spiders, Snow Troll livers, etc. and selling them at the market place. After all, people need food and potions need ingredients.
So how much gold then? My idea was that killed creatures remain on the table. Models can spend an action to retrieve the valuables. This will yield the warband the creature's hit points x 2 in gold coins. So a mere skeleton will only yield 2 gold coins (who needs rusty swords eh), but a Giant Worm will give you a whopping 40 gold. If a model claims a killed creature, remove the killed creature from the table.
What do you think?
