If you have the marking map it will track mesprit, just don't fly.
anywhere
you need the marking map on your poketech and the you go between sangem town and route 219 until he will be down in the marking map and then go into the sea there
I think you go and catch it in it's cave.
You can catch Dialga, Uxie, Azelf, and Mesprit
Yes, to catch Giritina, Cresselia, and Mesprit. In Pokemon Platinum, you can catch Zapdos, Moltres, and Articuno also. :)
You can't, you will need to trade them from Pokemon Diamond, Pearl or Platinum.
In Pokemon diamond you can catch Dialga, Azelf, Uxie, Mesprit, Cresselia and Arceus
Catch better Pokemon
You will need to catch the three lake lengendary pokemon. (Mesprit, Uxie, Azelf).
Dialga, Uxie, Mesprit, Azelf, and probly Arceas.
well in Pokemon diamond it can be possible to catch all of them but the easiest ones are dialga,shaymin,mesprit,and the other two lake Pokemon i cant remember the names.
No. Mesprit, Uxie and Azelf can be caught normally, they're just extremely hard (especially Mesprit).
