Karma
From FlyFF WIki
Karma, also known as an 'action' or 'deed'. Just like in real life, this can also be considered with Flyff. Karma is used for PK'ing (player Killing). A little explanation now about the Karma. If you are playing, you'll see that your char has a white name. It's on every Cluster with exception on Demian, since it's the PK Cluster. If you PK someone, then the color of your name will change. It will turn pink if you attack someone and it will get red if you kill someone. If you have a colored name, then you'll have a high chance of being punished for it. Every color (exception for white) has their own restrictions.
More information will come soon.
