2. Equip the Basic Skills from the Squire class. Make sure you have Accumulate and do not have any abilities that can counter attack your enemies. Now go into a battle and kill all but one enemy. Then just go into a corner and cast haste on the character and keep using Accumulate as much as you want.

3. Equip the Sing Skill from the Bard class. Now go into a battle and kill all but one enemy. Then just go into a corner and cast haste on the character and keep singing songs such as Life Song or Angel Song because these are the fastest songs they have.

Duplicating Weapons:
You must have the two-swords support ability from the Ninja class to do this. Equip a shield in the right hand and the weapon you want to duplicate in the left hand. Go to any shop and choose best fit and purchase the stuff they give you. Then go to the formation screen and remove the items. Now you have two of the original weapon. Just so you know though what ever you duplicate you have to pay for it.

Auto-Potion Trick:
Equip your characters with the Auto-Potion reaction ability from the Chemist class. Get rid of all Potions and Hi-Potions that you have in your inventory. Buy a lot of X-Potions. Now most of the times when you are attacked you will use a X-Potion giving you 150 HP.
