How to unlock Pokémon BDSP underground

the Pokémon BDSP underground man

The first thing you need to do to unlock the Grand Underground in Pokémon BDSP is talk to the Underground Man – who, funnily enough, isn’t underground at all. Head to Eterna City and visit the house to the right of the Pokémon Centre to find him.

After you have a chat with him, he’ll give you an Explorer Kit, and run through a quick tutorial on how to use it. Then, the Grand Underground is yours to explore.

Pokemon BDSP Underground player running towards a Diglett

Pokémon BDSP underground Diglett and Dugtrio

A fun new mechanic introduced in the Pokémon BDSP underground is the Diglett feature. As you traverse the tunnels, you’ll occasionally come across Diglett and Dugtrio at junctions and corners. They’ll run away when you spot them, leaving energy behind – Diglett leave one point, and Dugtrio leaves three points.

If you manage to gather 40 points in one Underground session, you’ll bag yourself a neat buff for four minutes, this increases your chances of encountering a shiny Pokémon. The shiny Pokémon encounter rate goes up from one in 4096 to one in 2048.

It also gives you a 100% chance of digging up a gorgeous box that contains a shiny statue. This chance boost runs out after you dig up three gorgeous stone boxes.

Pokémon BDSP Underground hideaway

Pokémon BDSP underground hideaways

A brand new feature in Pokémon BDSP is the Hideaway system. These are unique biomes that appear underground, allowing you to find a variety of rare Pokémon specific to each type of biome. A lot of these critters are exclusive to their hideaways, and they have a chance of coming packaged with one of their egg moves right out of the gate. There are different unlock requirements that will cause new Pokémon to appear in various Hideaways underground. They are:

  • Strength – Obtain the strength HM from the Lost Tower on Route 209
  • Defog – Obtain the defog HM from the Great Marsh in Pastoria City
  • Seven badges – get your seventh badge from Candice at the gym in Snowpoint City
  • Waterfall – Talk to Jasmine in Sunyshore city after you get your eighth badge from Volkner
  • National – see all 150 Sinnoh Dex Pokémon and unlock the National Dex

When you go into a Hideaway, there’s also a chance of encountering a rare spawn, which is a Pokémon not in the Sinnoh Pokédex.

okemon BDSP Underground digging mini game

Pokémon BDSP underground digging

Digging makes its return to Pokémon BDSP, and is pretty much unchanged. Simply use your radar while wandering around the Grand Underground, to highlight spots that can be dug up. This will start a minigame.

The minigame tells you the number of items hiding in the square on the screen. Then it’s up to you to hunt for the goodies with your Explorer Kit’s trusty pickaxe and sledgehammer! The sledgehammer removes larger sections of rock quicker, but causes the walls to collapse faster, whereas the pickaxe chips away small pieces, while dealing very little damage to the walls.

There’s a crack at the top of the screen that acts as a meter. When the crack reaches all the way to the left side, the walls will collapse, and you’ll be able to claim what rewards you’ve dug up. Check the lists below to see what’s up for grabs.

okemon BDSP Underground player talking to NPC

Pokémon BDSP underground NPC locations

As part of the questline needed to unlock Spiritbomb, after placing an Odd Keystone in the Hallowed Tower, you need to talk to 32 different NPCs in the Grand Underground. They spawn at random places, so unfortunately we don’t have a map of the NPC locations – you’ll have to do some legwork! Sphere Traders and Hikers that sell items don’t count towards your tally either.

Pokémon BDSP Underground Secret base

Pokémon BDSP underground secret base

If you played the previous versions, you’ll be familiar with secret bases, but the Pokémon BDSP underground secret base has had a bit of a revamp.

To build your secret base, you just need to use the digging drill item anywhere underground. You can move it at any time by purchasing another digging drill from an underground vendor. Vendors can also expand your secret base, for the following prices.

Expansion one:

  • 60 red sphere S
  • 60 blue sphere S
  • 60 green sphere S
  • 30 prism sphere S
  • 30 pale sphere S

Expansion two:

  • 40 red sphere L
  • 40 blue sphere L
  • 40 green sphere L
  • 20 prism sphere L
  • 20 pale sphere L

Pokémon BDSP Underground Medichan statue

Pokémon BDSP underground statues

When your base is built, other players can come to visit, and you can also decorate it. But instead of furniture like the previous versions, Pokémon BDSP statues are your new choice of decor – and they’re much handier than the furniture.

The statues you place in your secret base affect the Pokémon you encounter in the hideaways, so if you’re looking for Pokémon of a certain type, be sure to place as many of the appropriate statues as you can – for example, if you’re want to catch some water-types, aim to place water-type statues like Squirtle, Wartortle, and Totodile. You can place 18 statues at a time, and only one boost can be in effect. The type with the highest value (more statues, special coloured statues, etc) will always take priority when it comes to boosts, so be mindful of what you place in the base to maximise the benefit.

There are three types of statues, with varying levels of effectiveness.

Type of statue Where to get Effect
Standard statue Found in pretty boxes Standard boost rate
Colour statue Found in gorgeous boxes x2 boost
Legendary statue Obtained when a legendary is caught in Ramanas Park x3 boost
