This trick will duplicate any item that can be "stacked" in the inventory. One of the best uses is to duplicate gems to create an unlimited source of gold. Place a potion of healing in one of the quick items slots. Open the inventory screen, replace it with a gem, then immediately return to the game screen. The image of the potion should still be in that slot, but the gem's name should appear on the help scroll if the pointer is left over that slot. Left click on the gem once, wait for the target cursor to disappear from your character, then left click the gem a second time. After the target cursor disappears again, return to the inventory screen. The number of gems in that slot should now be 65352 instead of 1. Do not stack any additional gems in that slot, or the CPU will reset the total to 20. Note: This trick works with the original release of the game and may not function in patched versions.
