Exp share in Pokemon Diamond?
The Exp. share is a held item you can give any Pokemon. Basically you make a Pokemon hold it and it will gain half the experience of every battle as long as that Pokemon is in your party. For example: let's say that one of your Pokemon knocks out a wild Pokemon and gains 100 exp. points. The Pokemon that battled gets 50 of those points and the Pokemon holding the exp. share gets the other 50 without even having to appear in the battle at all. It is great for training weak Pokemon and saves you the time of having to switch between Pokemon.
