Players represent magicians of four different magic schools based on the four elements: Fire, Air, Water and Earth. The basic game mechanic consists of "magical" gestures representing these elements. The game is performed in freeform, semi-larp context.
Have fun watching i.e three magicians of the "School of Voluptuous Eruptions" perform fre magic by demonstrating gestures of sexual prowess! Ideally, this is played with an audience, rating the performances and providing additional background actors. Nonetheless, you can also just duel with two players behind closed doors.
