House Rule goes into effect tonight!
After combat, you may try to collect your used missile ammunition. You must roll a die, or combination of dice, that most closely represents the number of missiles you fired (without being greater) and collect that many. The rest are lost broken or lodged too deeply in an opponent to be removed.
I.e. You threw six darts, you rolled a 4 on a D6. Two of your darts are gone.
You shot 27 arrows, you roll D20 and a D6, and collect 15 arrows.
