To beat Mammon easily you will need high MP and a lot of MP replenishing items. You also need to stay as far away from him as possible (but not out of range of your magic attacks.) Now blast him with FIRE 3 and AVALANCHE until he's dead. He usually uses three spells, a spell like homing arrows which is hard to dodge, a spell that is like magma ball which is easy to dodge, and a spell that is like wind bomb which is easy to dodge. Just keep using FIRE 3 and AVALANCHE and dodge his attacks. He will die in a few minutes. He has around 2,100 Hp.
If your close enough to do combat with your staff, hit "A" and then choose a spell and hit "A" again.
When you get to Dondoran, Get the free Fresh Bread and the free Golden Wings. Go outside Dondoran and fight every monster you can find. Fight until you have used your Fresh Bread and you are at 1-10 HP left. Then use your Golden Wings. Repeat over and over again until you have about 70-80 HP then go into the forest and kick some.
When in a battle, use the staff attack as much as possible. It can be quite powerful, and increases your health points and replenishes mana.
A good way to get a collection of items is to first go to a place such as a house or mess hall where you can get items by talking to people. Then, go to the chests that contain the same item as the one you collected, and get the item out of that chest. This works because people will not give you items that you already have in your inventory.
When you get a spirit and it asks you to choose an element, press all four C- buttons at the same time and they'll ALL increase. This may take some practice as you must press them at EXACTLY the same time.
Once you've defeated the Robber in the forest, go back to Dondoran. The people tell you different things. When you go back to the king he'll open a secret throne room behind the throne with lots of goodies inside.
In the beginning of the game, pump up your WATER spells as high as possible. This will get you more life and the much-needed healing spell.
