Buy it at the poKemon league
I'd say a dusk ball or a timer ball
You can buy them at the Pokemon Mart for 1,000 Pokedollars.
You can buy the dusk balls in Pokémon Diamond at various markets in the game. The dusk balls cost 1000.00 a piece.
well one way is that they have a lot in the elite four building.
You can get a free dusk ball in Oreburg City. Right when you pass through the tunnel, walk forward a little. there is a two story house right on top. go to the second floor and talk to the lady closest to the stairs. she will give u a free dusk ball.
in pearl you use the dusk stone on misdreavus and in diamond you use the dusk stone on murcrow in pearl you use the dusk stone on misdreavus and in diamond you use the dusk stone on murcrow
If you use a Dusk Ball inside a cave, it will always be at its most effective catch rate. However, you need to use a Dusk Ball between 8pm and 3:59am outside caves to take advantage of its 4x catch rate. This is the game's night-time mode and Dusk Balls are more effective during this time.
if you have masterball use it but if you dont have try to catch it at night and use dusk ball
the best way to catch darkia is to use dusk balls or wait 10 or 15 turns and use a timer ball
When you catch up to Cryus (the leader of team Galactic) at the Spear pillar. After that make sure dialga's life is at the yellow or red zone the use a dusk or ultra ball , if that doesn't work use your master ball, while you are catching dialga in the master, ultra or dusk ball press a , b , b, b than after while the master , dusk or ultra ball shakes left press y.
In diamond? Pearl? Platinum? Sorry, I don't know about Platinum but I know that for Diamond - and I'm pretty sure Pearl also that you have to buy it after you collect a certain number of gym badges.
Yes, you can catch Dialga without a Master Ball. Dialga can be caught with any kind of Poké Ball but Dusk Balls and Ultra Balls would be the better options.
