Pokémon Go has added its second free Master Ball to the game (and third Master Ball overall), as part of a lengthy Masterwork Research called “Catching Wonders.” As usual with these Masterwork Research Tasks, this is a marathon, not a sprint, and it’s meant to be completed over a long period of time. There’s no time limit on the Master Ball research.
There’s also a short event that’s running alongside the permanent research, from May 14-19. During this event, you’ll get 10 times the XP for your first catch and PokéStop spin of the day. You’ll also get five times the Stardust for your first catch of the day. The event Field Research tasks also reward Stardust, XP, Poké Balls, Great Balls, and Ultra Balls.
