OOC actions are those that your character would not be able to realistically accomplish and are therefor done by the player but not the character. Some examples of OOC are:
Any knowledge gained in an OOCly way (You learn Player A is a Male Channeler over Chat) cannot be used ICly. (You can't then go take your level 5 CoTL and cut him down for being a Male Channeler)
All IC/OOC disputes are taken very seriously and we will side with the plaintiff if the defendant cannot produce logs, or has not submitted the log through RP submission, of how he gained such knowledge ICly.
