Shiny Odds: Odds of Getting Shiny Pokemon

Shiny Rates Increase with Higher Research Stages and with Mass Outbreaks

Pokemon have a Base Shiny Rate of 1/4096, and its shiny rate is further affect by four different factors that increase the chances of finding a shiny. Three of these are tied to Pokedex Completion, with the last one related to Mass Outbreaks and Massive Mass Outbreaks.

Conditions	Effect on Shiny Rate
Have a Pokemon Entry reach Research Level 10	1x the Shiny Rate for that Pokemon
Complete 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
Encountered 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 Massive Mass Outbreaks?

Simultaneous Mass Outbreaks Across the Map

Much like Mass Outbreaks, Massive Mass Outbreaks spawn tons of Pokemon within a specific area all across the map.

Unlocked After Completing Request 95

Massive Mass Outbreaks are only available once you have finished Request 95: A New Anomaly. This is included in the new Daybreak Content from Update 1.1.0!

Although Request 95 unlocks these new outbreaks, we also recommend finishing all requests from 95-101 to unlock Request 102: Daybreak!

Daybreak Request Guide and Walkthrough

Only Occurs During Specific Weather Conditions

Massive Mass Outbreaks will only occur when it is raining or during a blizzard, and will end once the weather condition has passed.

While Massive Mass Outbreaks only occur during these weather conditions, trying to change the weather does not spawn more Outbreaks.

Once a Massive Mass Outbreak ends, you'll need to return to Jubilife Village and come back repeatedly until a new Massive Mass Outbreak is shown on the map.

Spawns a Mass Outbreak of Alpha Pokemon

You can encounter a Mass Outbreak of Alpha Pokemon during Massive Mass Outbreaks.

As if a single Alpha Pokemon weren't dangerous enough - always be prepared with Smoke Bombs and Stealth Sprays to keep yourself safe should you come across an Alpha Outbreak!

Good chance of encountering Shiny Pokemon

You'll have a better chance of encountering a Shiny Pokemon in the Massive Mass Outbreak, as only one kind of Pokemon will appear. Use this chance to add more Shiny Pokemon to your collection!

How to Trigger Massive Mass Outbreaks

Depart and Return to Jubilife Village Repeatedly

Chances for a Massive 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 Massive Mass Outbreak in one of the areas.

The Pokemon that appear in the Massive 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!

In addition, any ongoing Massive Mass Outbreaks disappear when returning to Jubilife Village. Be sure to keep that in mind!

Rerolling Massive Mass Outbreak Lineup

It is recommended to save before entering a going into a Massive Mass Outbreak. Afterwards, enter the Mass Mass Outbreak area and feed Warden Mai's Munchlax to know the lineup of the Mass Outbreaks in the map.

Should the lineup of the Massive Mass Outbreak not be what you wanted, you can load the game and reroll your chances of getting other Pokemon!

Where to Find Massive Mass Outbreaks

Check the Map on the Arc Phone

The Arc Phone will show you where a Mass Outbreak is on the map. It will also show what Pokemon is on the outbreak upon visiting the location or through feeding Mai's Munchlax five Aguav Berries.

It will be helpful to you, especially if you're looking for a specific Pokemon and a shiny version of it!

Map Symbols and What They Mean

Massive Mass Outbreak Symbols
To be Uncovered	Standard Mass Outbreak
Special Mass Outbreak	Drops Aguav Berries

Question Mark: To Be Uncovered

The question mark icon found on the map indicates a Mass Outbreak area you have yet to uncover. It will only reflect on the map once you have discovered the Pokemon spawning in the area or if you decide to feed Warden Mai's Munchlax with Aguav Berries.

Standard Mass Outbreak

The usual Mass Outbreak symbol on the map. However, clearing standard Mass Outbreaks during Massive Mass Outbreaks have a low chance of spawning another set of Mass Outbreaks in the same spot, and are typically Alpha Pokemon.

Note that it is possible to find evolved versions of Pokemon, including special evolutions such as Ursaluna!

Star: Special Mass Outbreak

A Mass Outbreak icon that has a star indicates that another Mass Outbreak will spawn right after clearing the Mass Outbreak before it. Typically, it would be the previous Pokemon's evolution and will be of a higher level.

You can also come across Mass Outbreaks of Alpha Pokemon during the second wave of these Special Mass Outbreaks.

Outbreaks that Drop Aguav Berries

A Mass Outbreak symbol on the map with a berry on top indicates that specific Mass Outbreak has a chance of dropping Aguav Berries, which can be used to feed Mai's Munchlax in order to know the other Mass Outbreaks in the map.
