Paldea Pokedex
▲In this image, you are at the Habitat of the Pokemon of the Southwest Area of Alfornada
Once you have identified the Habitat of the Pokemon you are looking for, travel to that location. You don't need the Pokemon to spawn yet.
When you have an activated Encounter Power effect that matches the type of the Pokemon you are hunting, it's more likely to appear. It is recommended to have it active when hunting in Mass Outbreaks. Activate Lv 2 with a recipe that does not use a Herba Mystica or activate Lv1 at the store.
Encounter Power Sandwich/Food List
Once you arrive to the Habitat, repeat the date change until the Pokemon you want has a Mass Outbreak. While doing this process, it is recommended to return to the home screen with the map open to easily check the Outbreaks after you change the date.
How To Change The Date
Please use it at your own risk as it may affect game performance.
 | ① Select System Settings on the Switch's home screen |
|---|---|
 | ② Select System → Date and Time from the setting |
 | ③ Advance the date by one day (Turn off Synchronize Clock via Internet) If it is about 23:00, it is possible that it will overlap the date, therefore update the date as well. |
| ④ Return to the game and check the map |
Once the Pokemon you are looking for has a Mass Outbreak, head to the actual location. At this time, if the spawn conditions of the Pokemon you are looking for are not met, that Pokemon will not have a Mass Outbreak even if you go to the specific location.
Mass Outbreak Guide
Defeating 60 Pokemon during Mass Outbreak will increase Shiny appearance rate, so use Let's Go! to start battles and defeat as many as you can. If a Shiny appears in the process, you don't have to worry because your Pokemon will not defeat a Shiny.
Check For The Notification Where It Shows That The Pokemon Is Running Low
When 50 Pokemon are defeated during a Mass Outbreak, a notification appears in the upper right corner of the screen saying that there are only a few more on the way. When you get this notification, defeat 10 more to get a total of 60 Pokemon.
After defeating 60 Pokemon, turn off Autosave in the settings and then manually Save.
Recommended after completing Tera Raids so you can receive materials.
After saving, make sure to eat a Sandwich with a Sparkling Power that matches the type of Pokemon you are hunting to increase your chances of catching a Shiny Pokemon. It is possible to reroll without eating Sandwiches, but if you want to increase the ratio of getting a Shiny, then consuming Sandwiches with Sparkling Power is highly recommended.
Sandwich Recipes List
If you open Picnic and then quit, the Pokemon around you will be reset. This means that Shiny can be rerolled without defeating it first, so a Shiny reroll is possible without ending the Mass Outbreak. It is recommended to check the appearance of Shiny in advance, as it will speed up the process.
Shiny Pokemon List (Shiny Pokedex)Let's Go! Recommended For Pokemon That Are Difficult To Distinguish From Shiny
In the case of Pokemon that are difficult to determine if they are Shiny or not, the process of resetting the picnic and then checking them manually takes up time, When the Mass Outbreak is over, return to step 6 and repeat.
Make sure to hit save when you are able to get a Shiny or when you see one, so you can load back just in case. This is the final reroll procedure.
Probability Of Getting A Shiny
| Mass Outbreak | None | 30〜59 Pokemon | 60 Pokemon or more |
|---|---|---|---|
| None | 1/4096 | 1/2048 | 1/1365 |
| +Shiny Charm | 1/1365 | 1/1024 | 1/819 |
| +Sparkling Power Lv3 | 1/1024 | 1/819 | 1/683 |
| +Shiny Charm +Sparkling Power Lv 3 | 1/683 | 1/585 | 1/512 |
All Shiny probabilities are increased with each feature. You'll need to complete your Pokedex the Shiny Charm,and ★5 Raids to get the Herba Mystica that activates the Sparkling Power, so if you want to do a Shiny reroll, it's recommended to do it after completing the game.
