Mass Outbreak Shiny Odds

About 26x Higher Than Standard Odds

Mass Outbreaks have greatly increased Shiny Odds, and are actually about twice as high as the rate for Massive Mass Outbreaks. Shiny farming through Mass Outbreaks is useful for when you want to farm for a specific Shiny Pokemon.

Conditions Effect on Shiny Rate
PLA - Research Level 10 Icon.png
Have a Pokemon Entry reach Research Level 10		 1x the Shiny Rate for that Pokemon
PLA - Perfect Research Level Icon.pngComplete all of a Pokemon's Research Tasks 2x the Shiny Rate for that Pokemon
Having the Shiny Charm 3x the Shiny Rate for all Pokemon
PLA - Mass Outbreak Map Marker.pngEncountered during a Mass Outbreak 26x the standard Shiny Rate for that Pokemon
Encountered during a Massive Outbreak 13x the standard Shiny Rate for that Pokemon

The optimal rates for Shiny Pokemon require the Shiny Charm and all research tasks for that Pokemon completed for a Perfect page, and encounter the Pokemon through as Mass Outbreak.

Mass Outbreaks vs Massive Mass Outbreaks

While Mass Outbreaks have a higher shiny rate than Massive Mass Outbreaks, Massive Mass Outbreaks are generally more reliable for hunting shiny Pokemon.

Special Mass Outbreaks will cause a Mass Outbreak to spawn right after clearing the Mass Outbreak before it. The second spawn will also be the previous Pokemon's evolution at a higher level, and also has a chance to spawn as an outbreak of Alpha Pokemon.

The possibility of a second mass outbreak spawn in the same location makes shiny hunting more efficient, and it also makes hunting for Shiny Alpha Pokemon easier compared to waiting for them to spawn in their static encounters.

What are Mass Outbreaks?

A Large Number of a Certain Pokemon Appearing

PLA - Starly Non-Shiny Outbreak.png

Mass Outbreaks spawn tons of Pokemon within a specific area. They can happen anytime and anywhere on the map. However, only a certain Pokemon will come out on the outbreak.

Sometimes, even Alpha Pokemon show up in these Mass Outbreaks!

High chance of encountering Shiny Pokemon

PLA - Shiny Starly Catch.gif
You'll have a higher chance of encountering a Shiny Pokemon in the Mass Outbreak, as only one kind of Pokemon will appear. Use this chance to add more Shiny Pokemon to your collection!
How to Get Shiny Pokemon and Shiny Odds

How to Spawn Mass Outbreaks

Depart and Return to Jubilife Village Repeatedly

PLA - Reroll the Area.gif
Chances for a Mass Outbreak occur each time you return to Jubilife Village. By going to a map, and returning to Jubilife Village, there is a chance you can trigger a Mass Outbreak in one of the areas.

The Pokemon that appear in the Mass Outbreak are random, but you can keep going back and forth until you get a Mass Outbreak of a Pokemon you want to look for.

Move between areas that don't already have Mass Outbreaks

Keep in mind that if a Mass Outbreak is already happening on the area you are moving to, there is a chance that area's Mass Outbreak won't change. It will be best to move between areas that don't currently have Mass Outbreaks.

Where to Find Mass Outbreaks

Check the Map on the Arc Phone

PLA - Mass Outbreak on the Arc Phone.png

The Arc Phone will show you where a Mass Outbreak is on the map. It will also show what Pokemon is on the outbreak. It will be helpful to you, especially if you're looking for a specific Pokemon and a shiny version of it!

Chance of Finding a Massive Mass Outbreak

PLA Massive Mass Outbreak Map

Massive Mass Outbreaks are simultaneous outbreaks that happen across the map. This is a new event brought about by the Daybreak Patch from Update 1.1.0!
