Pokémon Diamond and Pearl/Solaceon Town

Solaceon Town is a small, out-of-the-way town you will encounter around the middle of your quest. Despite it being small, it is definitely not insignificant. There are several services here that you will probably use for the rest of the game.

Points of Interest
The Newspaper Publisher house is located next to the Pokémon Center. The man inside will tell you to bring a certain Pokémon to him so he can write up an article for it. If you don't bring it within 24 hours, the deal is off. If you do bring the Pokémon within the time limit they will give you 3 of a random Poké Ball. The most commonly received Balls are Dusk Balls, Quick Balls, and Timer Balls.

The Pokémon Daycare is located at the top of Solacean Town. It is definitely the best aspect of Solacean Town. This is how it works: Drop one or two Pokémon off at the daycare with the lady. For each step you take, your Pokémon in the daycare will gain 1 Exp. Point each (therefore, dropping two off is best as the Exp. Points are not split). This is a great way to level up weak Pokémon. There are two catches to the service. The first is the fact that the daycare services are not free. For each Pokémon you put in the daycare, you are automatically charged 100. Then, for each additional level that is gained you are charged another 100. The second catch is the fact that you cannot choose which move your Pokémon will forget when it levels up and learns a new move. A Pokémon will not forget an HM move in this process, however. For example, you could lose the move Shadow Claw to the move Leer. The only way to avoid this happening is this: know when your Pokémon is going to learn the new move, and when it gets to the level before that, Fly or run back to the town quickly (Flying is better as you will not risk leveling it up on the way back). Then pull it out of the daycare (after paying the fee) and level it up to the next level yourself. Don't learn the move, and then return it to the daycare once more. Also, if you have 2 Pokémon in the daycare, there is a chance that they will lay an egg. for more info, look here. Also, Pokémon that evolve by leveling up will not evolve if they reach that level in daycare. They must be in your party in order for them to evolve.
