Normal Heads are gained whenever a player kills another player. Normal Heads can be sold to the King for 500 Treasure, 500 Timber, and 50 Essence, but that player can only sell enemy heads, friendly heads will not be sold. A player cannot gain a Head from an opposing player if the player has already killed the opposing player. The opposing player can still be killed, but the player that already killed him for a skull won't get another one for the next hour. After the hour is up he can yield a skull from that player again.
