A Secret Base in the Grand Underground from Pokemon Brilliant Diamond & Shining Pearl

A Secret Base in Pokemon Brilliant Diamond and Shining Pearl can be a useful place to rest and store items, so here’s everything you need to know to make one of your own.

Pokemon Brilliant Diamond and Shining Pearl bring back the Secret Base feature from the original games, but also give it a fresh lick of paint for a new generation, making them more useful than ever before.

A Secret Base is a small cave that the player can discover then furnish with a variety of useful items like dolls, statues, and items. The idea is that the base can serve as a rest and storage point on the map. However, you can only have one Secret Base at a time.

What you’ll need to make a Secret Base in Brilliant Diamond & Shining Pearl

Before you can make your own Secret Base in Pokemon Brilliant Diamond & Shining Pearl, you’ll need to unlock access to the Grand Underground and earn the Digger Drill item.

To do this, visit the Underground Man at Eterna City. He’ll give you the Explorer Kit to access the Grand Underground, and will also set you three challenges – complete these, and he’ll give you access to a Digger Drill.

Digger Drills can only be used once, but the good news is you can buy more if needed from the Underground Man.
