The Rules are as follows.
1. At the begining of the raid, a name is given to all raid members but the raid leader, as this skews the game. Every time this persons name is said over vent, you take a bong hit / toke / Shot etc.
2. If this person is infected with some sort of boss mechanic, ie; green slime on putricide, snobold on NRB, etc. You make a not and take a hit after the boss is dead / you wipe.
3. Should the person in question wipe the raid, everyone in the raid shall take a hit / toke / shot.
4. This is a terrible game and promotes drug use and dangerous amounts of alcohol consumption (with us anyways). Take a shot.
5. Your final place on the damage charts determines how many hits / shots you need to have. This promotes that the good players stay relatively sober, but only enough that they can carry the raid.
Feel free to add ruless you think are fair. If anything seems unreasonable to you, man up you b!tch.
I use this for my raiding guild in WoW.
