* New raiders start with 0 karma.
* +5 karma for showing up for raid on-time.
* +5 karma per boss kill (+5 additional for progression boss kill)
* Standard /roll is used to determine the winner of an item. However, you may choose to add your karma bonus to this roll. Use all of your bonus, or use none--no partial amounts.
* 50% of the karma used for your roll is lost on all wins, and your karma is rounded down to nearest multiple of 5. There is no loss if you don't choose to use any karma.
* Sliding tier window. People can only roll if their karma bonus is within 50 points of the person who's using the highest bonus. (This cuts out the lowest 12.5% from "getting extremely lucky".) If the highest karma used is 50 or lower, anyone eligible may roll with or without karma.
* Ties are decided by a straight /roll with no bonuses.
* Anyone rolling with karma bonus who is uncontested (i.e., only one person wants an item) may get the item as if declared "no bonus".
* Losses for wins are immediate. Karma is added at the end of the night.
* If you are told not to compete for an item by an officer, you may not roll. (This may be invoked in cases of multiple defaulted/free items being won by one person who then tries to roll on other things, or other situations that seem highly "unfair". Members are expected to not be greedy, but they are also expected to not collude, and to use their karma for items they actually want.)
* Possible bonuses given by raid leader to the entire raid, if a raid spends significant time to progress/learn how to defeat a new boss. Karma may also be individually granted to those filling in empty slots to help the raid.
