Mesprit is one of three Lake Guardian Pokémon that appear in Pokémon Go. You can catch this Pokémon in a five-star raid from September 14th to October 1st. You will only find Mesprit in Europe, the Middle East and Africa. If you are looking to take on this Pokémon, you may want to contact other players living in these regions to invite you to these raids. While playing Mesprit, what are the chances of capturing its brilliant version?
Starting September 14, the brilliant version of Mesprit will be available to everyone around the world. It will have the same chances as other raid Pokémon, where each has a one in 20 chance of a shiny version appearing at the end of the raid. Sometimes you can get lucky with your first raid, but it may take a few tries to encounter a shiny Pokémon after completing the five-star raid. You might get lucky and another coach offers to trade you a brilliant version.
Mesprit will be available until October 1st, after which it will disappear again. It's been about a year since the Guardians of the Lake last appeared in five-star raids, and it could take another year or so before they return. If you're eager to catch the bright version of him now, we highly recommend him, but you may need to map out where other trainers are and where Mesprit has a chance to appear. We expect the brilliant version of him to return when future raids appear.
