Pokémon Go is having a Beldum Community Day event on Sunday, Aug. 18, from 2-5 p.m.in your local time.

As expected with a Community Day event, Beldum will spawn in huge numbers with a high chance for it to appear shiny. There are also several other bonuses and perks, which we’ve list out below.

As per old research by the now-defunct website The Silph Road (via Wayback Machine), Shiny rates on Community Days are about 1 in 24, which means that if you keep playing throughout the three-hour window, you should find quite a few shiny Pokémon.

If you’re short on time or Poké Balls, you can pop an Incense, then quickly tap each Beldum to check for shiny ones, running from any that aren’t shiny. Notably, any Beldum you’ve already tapped will face where your player is standing, so that should help identify which ones you may have already checked.

If you evolve Metang into Metagross from 2 p.m. until 7 p.m. in your local time, it will learn the charged move Meteor Mash.

If you miss out on evolving it during this period, you will likely be able to evolve it during a Community Day weekend event in December to get Meteor Mash. If you don’t want to wait, you can use an Elite TM to get the move.

Metagross is one of the best steel-type Pokémon in the game, only really getting outclassed by Dusk Mane Necrozma (an event-only Legendary Pokémon/Ultra Beast, so take that as you will). Even better is a shadow Metagross, so if you have an opportunity to nab a shadow Beldum from a Team Go Rocket member and you have the resources to level it up, you definitely should.

Metagross’ best moveset is Bullet Punch and Meteor Mash and with this, it’ll make pretty quick work out of most opponents — especially fairy-, ice-, and rock-type Pokémon.

Mega Metagross has not been added to Pokémon Go yet, but you should use this as an opportunity to nab a good Beldum with the intention of eventually using it to get a Mega Metagross. While we can’t confirm any details yet since it’s not in the game, it will very likely be extremely powerful and worth having.

The following bonuses will be active during Beldum Community Day:

That said, you should definitely put some eggs in Incubators and pop an Incense and try to nab some powerful Beldum.

If you can Mega Evolve Alakazam, Slowbro, Steelix, Scizor, Gardevoir, Latias, Latios, or Lucario, you’ll score additional Beldum Candy per catch.
