Shiny Pokémon, having existed in the games since Pokémon Gold & Silver once again make a return in Pokémon Legends: Arceus. However, as always there are a few tweaks. The standard rate remains at the general 1 in 4096
This game also reverts the addition of Star/Sparking and Square/Glistening Shiny Pokémon, with there only being one Shiny animation. The sound of a sparkle can be heard when a Pokémon spawns in, even if you're at a distance or flying over, allowing for you to tell if a Shiny is near. You can also save in front of one in case it fails
In this game, all Legendary Pokémon and the starters (as gifts) are Shiny Locked, but you can get Shiny Starter Pokémon in Space-Time Distortions.
There are, however, a few other ways to improve your odds.
Next up is a simple boost that you get to Research Level 10 for the specific Pokémon in the Pokédex. This boosts the rate by 1 to a 2 in 4096 chance. This can be boosted even further to give you an extra 2 rolls if you get the Dex Research Perfect.
Next is the Shiny Charm, which you get for getting Research Rank 10 with all 237 non-Mythical Pokémon within the game. This then boosts it by 3.
Mass Outbreaks have been a big thing in Pokémon games for many years but have returned in this game. These Mass Outbreaks are worth checking out because they have an increased chance of a Shiny spawn. It shifts up by an additional 25 shiny checks so 26 in 4096 as standard
Only 4 Pokémon spawn in Mass Outbreaks at once, but more can be in it when you defeat the ones that spawn.
Massive Mass Outbreaks also have an increased shiny chance but not as much as Mass Outbreaks, only 12 additional rolls
