Tales of Symphonia Cheats :
Secret - Maxwell, the Summon Spirit of Birth
Go to Exire. Go behind elder's house (it looks same as the other houses but it's above few steps). Walk forward a narrow path until you arrive to a grave-looking stone. Equip Ruby, Aquamarine, Opal and Garnet to your first four characters and then examine the stone.
This is a king of all Summon Spirits and you must have a Derris Emblem to battle him. When he uses Meteor Storm, use guard tech three times to guard it. You can evade other techs like normally. Maxwell isn't very hard, so this battle shouldn't be a problem. Recommended level for this is 60-65.
