Machiavelli

A multipurpose bot that helps with moderation, has some fun commands for members of your user to user, such as >kill, >cookie, and more, and an activity system called the Virtu system, inspired by Machiavelli, which tracks user activity and rewards them for it with higher and higher levels. To make things more interesting, you can attempt to rob virtu from another member, but that may not always go your way...

Additionally the prefix can be changed per server.
