Multiply items
Enter a town, locate a training room, and saved the game. Create a
temporary character. Remove (not delete), one of your regular
characters from the party. Add the temporary character to the
party. Place the item or weapon to be duplicated into the temporary
character's inventory. Remove the temporary character from the
party. Add the regular character back into the party. Remove all
characters from the party, then reload the saved game. The item or
weapon should be in both the original and temporary characters'
inventories. Repeat this process to duplicate the item or weapon as
many times as needed.
Quick gold
Create one permanent and six temporary characters. Add all six
characters to a party and transfer all gold to the permanent
character's inventory. Have the permanent character buy any
equipment or items. Remove the permanent character from the party.
Create and add another permanent character to the party and repeat
this process until all permanent characters have the desired gold,
items, or weapons.
