Get next to a save point. Save your game. Drop the items you wish to duplicate. Reload your character. Pick up the dropped items. Repeat this as may times as desired. You will have the number of items you had when you saved plus the ones that you picked up after reloading.

This trick requires at least two characters. First, save the game. Then, have one character drops all their items. Next, have the other character pick up all the items, sell them, then buy whatever desired. You can then reload the character that dropped all their items. Note: In two player games, gold is shared; if you reload the character after selling all the items it will reset the gold to the saved amount. If playing in single player mode, start a second game and save it. Then load the saved game you want to duplicate in. Import the saved character from the other game into the game you are playing and save. Then, repeat the process. When done, export the second character and continue your game. Note: This works well for the workshop. Before selling duplicate items, check to see if they have gems. You can break them out to have gems to work with that are not for sale at first. Also, buy weapons that have gems and break them for extra gems.

If you have items that you want to duplicate, go to a battle area with a save location then save the game. Drop the items to be duplicated on the ground. Then, select "Load Character" and reload your character from the same save. Pick up the item and you should now have two of them. You can use this to make a lot of money by duplicating gems and runes. Sell them, then duplicate them again and repeat. Then make a big item, such as armor with sixteen runes, sixteen gem slot one, and sixteen gem slot two. Upgrade the item, duplicate, then sell it.

To play a Drizzt or Artemis easily, enable the "Cheat mode" code, then use the level warp cheat to go to the BGate3 map for Drizzt. Do the same under the extreme difficulty setting for for Artemis.

Find a save point, then save the game. Turn off the Xbox, then turn it back on. Load the game that was just saved. Enable the "Level 10 character" code to get 500,000 gold, 45 feat points, but will still be at the same level and have the same items. Repeat this as many times as desired for more feat points. Note: You must have less then 500,000 gold when you do this.

Successfully complete the game under any difficulty setting.

When using Dark Possession on creatures, you can use Flame Arrow and it will harm the creature you took control of, but the spell will stay on them as if you never hit them.

To defeat Argesh, leader of the Hands of Glory without getting hurt, get a long range weapon, (for example, a bow). Stand close to the row of boxes where there is a gap. Stand close enough to the boxes so that Argesh's underlings will not see you. Shoot or throw your ranged weapon through the gap to hit Argesh. Note: Some arrows will not make it through, but others will. He will charge in your direction does not go around the boxes. Keep shooting him until he is defeated. At that point, most of his underlings will also be dead.

A quick way to escape from the beams that the Basilisk shoots is to jump until you are not slow anymore.

When battling the Green Slimes in the Sewers, use weapons that have large damage attacks, such as swords and maces. When attacking the slimes, hang around the edge of a corner and let them come to you. Then, ambush them when they are close enough to your character. This is the best way to battle in the Sewers, and it saves your health potions.

When fighting in Luvia's Laboratory and you get to the end where she sends two beasts to attack you, only go forward slightly. One of the beasts will chase you. Stay in the bottom portion of the room and use the crossbow on it. This is easier with two players. Eventually it will die and then you can defeat the second one in any way desired.
