The cause of many amusing incidents in
RolePlaying games, which are described on the
RolePlaying page, so won't be described here, unless someone other than me feels like being redundant. Anyway, second edition
ChaosMagic involves rolling on the Wild Surge table to see what happens. A lot. Third edition
ChaosMagic is scary and involves the Path of Whispering Something-or-other and characters dying at a very, very, very extremely very early age.
EvilSouthie has huge...
... Wild Surge table for ChaosMagic.
DonJon tends to be a bit like ChaosMagic, especially when the players are feeling suitably random. Hence the MagicalGayCyborgDisplacerBeastsFromAnotherPlanet?.
