When you find a good item in a dungeon, create a copy of the file that corresponds to that level to a backup directory. For example, after finding a good item on level 1, make a backup of the "Levels.1" located in the game directory. Collect the good item, then go down the stairs to the next level. Copy the backup file back to its original location. Return up the stairs and collect the item again. Note: Pets and monsters may freeze when the backup level file is reused. Use this trick to duplicate level potions, ability potions, energy potions, and unique items.
