How Does It Work?
Karma is a plugin that marks players depending on how they behave in pvp situations. Each player has a karma level. When they kill players that don't kill other players it goes down. When they kill players that do kill other players it goes up. There are three main karma levels. Neutral, Red, Green. Players start at Neutral. When there karma level goes up the turn green and when there karma level goes down they turn red. When players kill red players there karma goes up.
The second main feature of this plugin is yellow players. When a player hits another player they become yellow. When you or damage a yellow player your karma is not affected at all so you can use self defence.
