Claydonia Conquers the World! is an expansion rule set for Clay-O-Rama. Claydonia Conquers the World! was published in Dragon Magazine #144 pp. 28-31 April 1989. The original Clay-O-Rama game was also published in Dragon Magazine (issue 125) by David "Zeb" Cook. The original Clay-O-Rama had players make monsters (Claydonians) out of Play-Doh in order to battle each other. Powers from a list were assigned to each monster. Some Powers involve dice-rolling to hit, while others required actual physical actions such as throwing clay missiles or poking a finger through an opponent's monster. In the Claydonia expansion there are Campaign rules and a list of 15 new Powers. The Campaign rules include Claydonian Experience Level Advancement so monsters who survive can get tougher. The new Powers include dreaded attacks such as "Absorb Opponent", "Use Self as Missile", and "Stomp" (in which a player uses a shoe or boot). Expands: Clay-O-Rama
