Psh. Quit fooling people guys, Everyone knows that the Karma ratings here are directly correlated to your Parkour Luck. For example, Leon has more than 10 times postive Karma than Negative, which means that he is 10 times more lucky than a nuetral person in regards to his training. He falls less, breaks less bones, etc, and is just generally better. Ryan, on the other hand... probably shouldnt even get off the chair to walk outside, because doing so would risk serious injury, death, or even worse due to his extra high low Karma Score.
Also, Your Post count directly correlates to your PK prowess as well. The higher your count, the better you are. This can have interesting effects when combined with Karma. So you better be careful how you post on this here forum, because if you say' something that offends somebody, they have the option of potentially ruining your day's training. They might even be able to kill you THROUGH the internet.
Be a decent person, and you wont have any issues.
