Sword of Mana

By killing 1000 of the same variety of monster (eg: Kill 1000 Rabites), you will permanently replace that monster with a new, Black version of it. The Black versions of monsters are a lot stronger and tougher than their regular counter-parts, but have a relatively good chance of dropping Crystal Ores which can be used for forging. When a monster turns black it'll get +500 HP and +100 on the other stats

To see a brief sequence involving a chocobo, wait five minutes after the ''Fin'' screen appears when you complete the game. After the scene, the game will go back to the title screen.

Even if you do 0 damage, the game will still allow you to raise your weapon/magic levels. To raise a weapon/magic level easily, find an enemy that is invulnerable to the type of damage the weapon or magic causes (The Popoi's Notebook in the ring menu has information about this). Repeatedly hit it. Your weapon/magic level will raise as though you are causing damage.

This glitch may be hard at first, but after a while it will come naturally. Just equip the Bow and get very close to whatever you want to attack, then attack. If done correctly, it should hit the enemy twice, once when it was being pulled into the Bow, and again when it was released!

Every time you deal damage to a creature (even 0) you momentaraly stun them and you gain magic Exp. durring that stun time you cannot hurt them, so even if you are using the Knucks to cast spells you can only hurt them 3 times max. But that doesn't happen with bosses, so fell free to abuse them with magic that they are immune to and watch how fast your level increases!
