How do you find the 3 legendary Pokemon in Pokemon pearl?
In order to find the 3 Legendary Pokémon in Pokémon Pearl which
are likely Mesprit, Azelf and Uxie, first you have to free them
from their traps in the Team Galactic Veilstone Building. Once that
has been done, you can find Uxie in its cavern in Lake Acuity.
Azelf can be found in its cavern in Lake Valor. You will find
Mesprit in its cavern in Lake Verity however as soon as you
interact with Mesprit, it will fly off and it will begin to roam
around the entire Sinnoh region. Helpful recommendations for
battling Azelf and Uxie in order to catch them is first make sure
to save your game before interacting with them in order to start
the battle with them because they cannot regenerate once you knock
them out. Additionally any Poké Ball will work on them but Dusk
Balls are recommended due to battling them inside of a cave.
