Easier money
Use this trick to obtain an endless amount of money with a bit of patience. Do this at the start of a new game before you make the actual five or so characters that you really want to play with. The game will allow you to create up to twenty characters. Five can be in your active party. You can have the game automatically create the characters for you by pressing the button and it will randomly create characters and add them to the registry. All the new characters start with basic equipment, weak armor, boots, head pieces, and a particular weapon depending on their class. After the registry is full (the game will then inform you that no more new characters can be created), you can view all of the characters in the registry's equipment. Here, you can remove all their items and stockpile them. You can then go to the trade booth and sell all the equipment. Since the game does have weight requirements that determine how much your party can carry, use the stripped players to maximize your carrying capacity and minimize the trips to the trade booth. When all the automatically created characters' belongings are sold, delete them from the registry and repeat this method . This is a good way to get newly created characters the best gear in the shop right away, ceause the only way to make money in the game is to sell items that you find in the dungeon, or take on jobs. It is possible to make 30,000g in an hour and a half by using this trick.

Combos
To receive combos, attack with weapons and spells of the same property. For example, have a caster use an elemental spell like one of the fire ones that attack one opponent. Then, make sure a character is equipped with an elemental weapon like a sword or knuckle with the same type. You can normally tell what type an item is by the name or by the resistance it gives. For example, fire resistance for a fire weapon. If you use both attacks at the same time, it has a random chance for the two characters to do one attack, which does five to six times the damage compared to the non-combo regular damage. This will work best on Bosses.

Completion bonuses
When you finish the first 10 levels and the Demon Lord, save and go on. Levels 11 to 100 are now available. This will basically repeat the first 10 levels until 100, but with stronger enemies and powered-up items. The new items are mixed roughly 50% with the old versions. You will still find things that were in the beginning of the game. The only changes in town are at the Guild where the quests have included every monster and new levels. Be prepared to see quests for enemies up to level 800, and area searches around level 80 and up. Finding one fitting to you may be hard. To begin, you will only have access to levels 1 to 11, and after each 10 it repeats. Other than that, there does not seem to be anything else new besides the items. All the Bosses, enemies, and levels still look the same, with the same requirements.

Green rooms
Avoid the green rooms with the round computer inside. Once you are beyond level 5, the advantages they may offer are not worth the risk. The positive effects they give are few and far between the negative effects.

Faster battles
First turn the battle speed to maximum, and then turn off battle animations. This will make most fights that normally last a few minutes end in roughly ten seconds. Only do this if you are really strong and do not really care about strategy, but wish to save time.
