You probably should do this anytime you pass by cities but it may not happen at that point so return later after another major event.
In Toize valley mine you will find an white square as an enemy. That is Bacura the invincible block of Xevious, Namco\'s famous game( released in 1982)!!
After clearing 'Party Advanced Level' in the arena, there will be an Exhibition match with characters from other Tales games, and they are Garr, Farah Oersted and Meredy.
Equip Sheena with the Card of Lightning (found in the Meltokio Sewers or bought in Mizuho), the Thunder Cape (found in the Toize Valley Mine), and a Paralysis Charm (dropped by Iapyx or bought in Asgard). This will make her immune to lightning, which is the only type of damage Volt deals. The downside to this is that Sheena will also deal lightning damage, which heals Volt. Either use any color quartz item (except purple) or have Sheena use S. Seal: Water on herself to change her attack attribute to something else. Now you can just walk up to Volt and smack him around while he futilely attempts to zap you. These remedies are temporary and will wear off, though, so watch the numbers showing the damage you do. When they turn green, Volt is getting healed and you need to change your attack attribute again. To keep your other characters safe and out of harm's way, set their third strategy option to Hold Position.
To easily get the Gigolo title for Zelos, return to Meltokio after receiving the Spider Figurine, Chipped Dager, and Mirror Shard, but before picking up the Derris Emblem. Make Zelos your on screen character and go to his house, then talk to the butler to get the title. You would otherwise have to have Zelos hit on every female NPC in the game to get this title, but this way you don't have to flirt at all.
