The Formula is
40P > 1000N
Using this formula, we can work out exactly how many players are needed to kill N number of 'baddies', also known as mooks, without death or even injury.
Bad guys, use this formula wisely - for if you don't.. it shall be the end of you AND your guild.
Evil players are not counted into the equation: usually dealt with by specially requisitioned 'Super Good NPCs'. An example of this is Tirion Fordring.
