Lunar Legend

When you get the Angel Sword (in Protector's Cave) and Master Book, equip both of them on Alex to get his most powerful special attack, Liner. It does massive damage to one enemy.

Make sure that Alex has learned "Flash" (at level 18). You should have it by the time you reach Sub-Vane. If you do not, keep fighting the Snow Dogs in Sub-Vane until you learn it. After you learn it, buy two Quick Boots and equip them on Alex. Next, go to your menu, and then to "Tactics", change Alex's Tactic to "Flash", and everyone else's to "Defend". Enter a battle, select "Tactics", and Alex should wipe out all of the enemies on the field.

You can get the Angel Sword (in addition to Guardian's Card) by defeat the Guardian at Protector's Cave. He is found all the way at the end of the cave.

Go to Lann after becoming a Dragon Master and talk to the chief of the village. When he asks if you should celebrate, answer "Yes". After the celebration, he will give the Devil Tear to you. The Devil Tear gives you a full special bar at the beginning of every battle.

This trick allows you to duplicate your equipment. First, equip your characters with the item to be duplicated. You can do this with more than one item. Then, go into a battle and win. Save your game, then remove the item(s) to be duplicated that you equipped on the character. Save the game again. Load your game, and you should now have the item in your inventory (from when you unequipped it) and another one equipped. Repeat this as many times as desired. You can get unlimited money very early in the game by doing this, When you first get Nash, he is equipped with a Sorcerer's Robe. Use this trick to duplicate it, and sell each Sorcerer's Robe for 1,000 silver. When you get the Master Book, use the duplication trick on it. Each sells for 15,000 silver. When you get to Vane, buy the Wind Boots and duplicate them. They sell for 40,000 silver each.

To get a lot of experience early in the game, fight the Snow Dogs that appear in Sub-Vane (the place you go to when you first try to teleport to Vane). The Snow Dogs amount to about 150 experience points and near 1000 silver each. They are very fast and they run away. Equip yourself with items that increase speed. You can also fight their babies, the Snow Pups, encountered beyond the southern gate of Nanza (in the valley where you first meet Tempest). The pups give a little more experience and silver than their parents.

To duplicate equipment equip the item as you normally would. Unequip it and save, when you load up your game you should have 2 of the original item.

Before you buy any cards from the card shop, save the game in slot 1. Then buy as many cards as you want. After you finish buying cards, save your game in slot 2, then load your game from slot 1. You will have the cards you bought, as well as the money you spent on them.

All you have to do is save your game and turn it off. When you turn it back on all your characters will be at full health and magic. You can do it as many times as you want.

Petrify (using nash's stone skill or another skill) an enemy and then cast riot, it will do massive damage.
