How To Beat The Iron Giant
When you get to Kilanda,and get to the Iron Giant,when you first start have at least 3 people(one to kill him, one to distract him,and the other to do both).One or 2 of the characters have to have good defence(clavats or yukes) to block all of his attacks.Once he breaks his sword ,thats the perfect time to attack him.But, he can get new swords by plucking them from the ground around him.(Note):The little minions can use fire so when they do use it on you move around when the giant isn't attacking,but do it quickly!

Multi-player: Treasures and artifacts
You can walk off with only one artifact no matter what, however in a single player game you will have your pick of the mix. In a multi-player party, the hero with the most bonus points gets first choice. However, the artifacts tend to be superior.

Picking up items
Use the following trick to make the game go by smoother. Whenever you go into a level, pick up everything. That way when you complete the level, you can go directly to the nearest town and make a lot of gil. This will be very helpful later in the game when many of the materials cost a lot of money.

Additional shops
Additional shops will appear in Tipa after characters of various classes are present on your memory card. The more characters and varying classes, the more shops and types of them will appear.

Jegon River Boat
If the Jegon River runs dry, go to Veo Lu Sluice and cast Life on the dead yellow flowers in the area. This will allow you to use the Jegon River Boat and cross to Fields of Fum.

Mines Of Cathuriges: Pi
On the second "section" on the Mines Of Cathuriges, on the rafters, there will be three boards arranged in a fashion that resembles the mathematical symbol for pi.

Weapons for the Clavats
To get an Excaliber weapon, go to River Belle Path. Do a lot of magic spells to enemies to gain more points and use charge focus attacks. Pick up items, artifacts, and money to gain as many points as you can. After getting your points, defeat the Boss. After defeating the Boss, you will need at least 116 points to get the scroll called Legendary Weapon. The attack power is 33 and you will need Alloy, Orichalcum, and Ancient Potion.

Hard to find materials for weapons
After about Year 5 or 6, if you stay around Alfitaria and Shella you will often run into the Shella caravan (made up of all Yukes). They will ask to see one of the materials you have in your inventory. Sometimes it is something you rarely need late in the game, such as iron. Answer yes and they will make an offer to trade for it. Frequently it will be an item, such as a Hard Shell or Holy Water, that you can use to forge more weapons or armor.
