Castlevania: Circle of the Moon Cheats
First, you need at least two cards(attribute and action cards). Choose those cards and exit DSS and exit the menu.Hit "L" and then quickly hit start while the game is activating the DSS. Go to DSS, and choose the Saturn card(Third one to the left, top right hand corner),and the Manticore card(sixth one the right, bottom). If done correctly, a purple cloud should appear. You must get this cloud to actually touch the boss. Once that is done, it will begin attacking it and it won't stop until the boss is dead. Then, you can sit this fight out and enjoy the match from a safe distance.
