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.
You can wield the Eternal Sword but still have another sword equipped on Lloyd.
Step-by-step
1.Have Lloyd cast Falcons Crest (secret tech) by pressing and holding block (default X), attack (default A), and then tech (default B).
2.While casting a enemy must kill you the easiest way to do this is die and have Sheena cast Purgatory Seal on you so you have no HP then use Falcon's Crest.
3.When you are revived after dying during Falcon's Crest you should be wielding the Eternal Sword.
If you begin the Devil's Arm Quest, After a few Devil's Arm's, go to Altimira and sleep at the inn. Say yes that you want to go out at night. Head to the Casino Area. Go on the bridge and you will see a young man. He says he will sell you a kendama for 1,000 Gald. Say yes and then check your Gald. You actually spent 0 Gald!
Though Zelos may be incredibly vain and idiotic, he does have a way with the ladies. Make Zelos your onscreen avatar, have his Personal EX Skill equipped, then talk to any of the female townspeople that you meet during your travels. They'll usually give you some Gald or an item.
You can easily get two of the most powerful weapon for Presea, the Gaia Cleaver. When you are able to get it (after level 80 or when Presea has learned all of her techs in the tree you chose) go to Ozette again and speak to the man next to Presea's dad's grave. He'll give you the Gaia Cleaver. Now, without living that screen, equip it on Presea from the new items menu (not always works from the equip menu) and talk to the man again. He'll give you another Gaia Cleaver
