If your having a hard time on finding some forgery items (you know item synthesis item) you have to destroy a lot of each kind of monster and put on all your party members "Lucky Strike" and "Jackpot" (if you want to get rich). If your looking for elemental gems and items go to White Mushrooms and cast the same spell of the gem or crystal before it dies. (ex: Fire, Thunder, Thunder, it will give you a thunder gem)
