You need a Pokemon which knows the move "Mean Look" which will stop it from running away ghost Pokemon have that move like gastly.
Balls: You need Dusk balls or Quick balls you need the Marking Map it shows a monster icon that is where mesprit do not fly or it will go to somewhere else.
*alot of the time mesprit is faster that your Pokemon so before you use mean look equip the Pokemon with an X Speed (you can buy them on floor 2 in velistone city's department store)
Sometimes an easy way to get to mesprit is to fly somewhere completely random and mesprit will often move somwhere closer to you.
also, if you don't have mean look, then every time you encounter it, weaken it a little because then when it flees and you encounter it again, its HP will not have restored from the last battle. so when you finally encounter it and its hp is low, use a quick ball!
Hope this helps!
You get a Pokemon entry in your pokedex.
No, catching Mesprit is completely optional. If you're looking to get the most out of the game, though, you'll want to capture it along with the other legendaries.
Well nothing really you capture them and theyre just like regular Pokemon
You find it in the Galactic Headquarters after they capture Azelf, Uxie, and Mesprit.
No. You can simply meet Mesprit and it will fly off. Then, look in the tall grass/ocean of Sinnoh and you may see it.
Mesprit roams Sinnoh.
mesprit is a legendary Pokemon and legendaries don't have gender However, In Pokemon Mystery Dungeons, Mesprit is considered a giirl.
Mesprit is in the underground lake.
Mesprit never evolves. It-like most legendaries-does not evolve.
use a ghost type Pokemon with scary face so it cant run away and then use a dusk ball or a net ball and you will get it don't fly or it will run away
