---|---|
Start Location | Cube Corp., northwest side – Scientist |
Unlock Requirements |
|
Objectives | Defeat all 32 Raid Dens in Borrius in a single day |
Reward | Item: Porta-PC |
A scientist in Cube Corp. wants you to find and challenge all 32 Raid Dens spread across Borrius – and do it in a single day.
If you manage to do it, he’ll give you the Porta-PC.
Starting the Mission

After you become Pokemon Champion, Cube Corp. becomes accessible. It’s an endgame area that can be reached through Crystal Peak or through Redwood Forest.
Head west from the Redwood Forest entrance and you’ll see a Scientist with a mission for you.

There are 32 Raid Dens in Borrius, and he wants you to challenge and defeat all of them on the same day.
How to Complete

Raid Dens are challenges available once daily where you can battle a Dynamax Pokemon to receive rare rewards.
Most of them are located in Hidden Grottos, which can be identified by a deep shadow between trees. However, some of them require puzzles to open and are more difficult to reach.
We have a page listing all of the Raid Dens, but their exact locations are also detailed in the table below:
