The Chessboard is somewhere located inside the Gamesmaster Mansion. You will find yourself on a live chess, with white and black pieces ready to fight. Most mobs are low level between 10/20 . Rooks might be a bit higher. Theres some quests in here involving the Kings. Its fun but you wont earn tons of exp here. The quest prizes are nice. Also dont try to kill the golem unless you are experienced. And remember that to smash rock u need... I classified this area midlevel cause it not that hard. A group of milevels can take the biggest mobs im sure.
