Since now players can hit mobs from very far away with a fully charged bow, it's very easy to get loads of money without really doing anything but shooting from a high spot. It would be useful to be able to reduce the chance(%) or amount of money given from that kind of kill. Thanks!

It would be great to have different payouts per weapon. so we could have a default payout, and if we liked, specify an item (such as 0 for fists, 261 for bow, etc.) and have them payout differently.

Added feature to modify coin reward based on weapon used via gain multipliers.
