Walkthrough:Pokémon Brilliant Diamond and Shining Pearl/Part 5

This is the Bulbapedia walkthrough for Pokémon Brilliant Diamond and Shining Pearl.
These pages follow the remade Nintendo Switch iteration, not Pokémon Diamond and Pearl. The guide for those games can be found here.

Eterna City

Eterna City

Welcome to Eterna City, home to the second Pokémon Gym. Before challenging Gardenia and her Grass-type Pokémon, take some time to explore this historic city. Heal your team at the Pokémon Center first, then look around town.

Pokémon Center

Speak to the woman near the entrance of the Pokémon Center to receive the Friendship Checker app. It displays how friendly your Pokémon are toward you, useful for Pokémon like Budew that evolve through friendship.

Eterna Condominiums

The Eterna Condominiums building is next to the Poké Mart. On the first floor, you'll find the Name Rater, who can rename your Pokémon. Also on the first floor, a boy offers to trade his Chatot for a Buizel. Chatot is a Normal/Flying-type Pokémon not found in the wild at this point, so it's worth making the trade if you caught a Buizel on Route 205 or at Valley Windworks. On the second floor, an old woman will give you three copies of TM67 (Recycle).

Herb Shop

To the east of the Team Galactic Eterna Building is an Herb Shop selling herbal medicines. These are less expensive compared to standard healing items, but each use lowers your Pokémon's friendship.

Ancient Statue

Ancient statue

In the northern part of the city stands a large ancient stone statue. In Pokémon Brilliant Diamond it depicts Dialga, and in Pokémon Shining Pearl it depicts Palkia. There is a hidden Draco Plate behind the statue.

Just north of the statue is the Team Galactic Eterna Building, currently occupied by Team Galactic. You'll tackle both the Eterna Gym and this building in the next part of the walkthrough.

Underground Man

Next to the Pokémon Center lives the Underground Man. Speak to him to receive the Explorer Kit, which lets you dive into the Grand Underground, a vast network of tunnels beneath all of Sinnoh. Down there you can dig for Fossils and treasures, catch rare Pokémon in Pokémon Hideaways, and build a Secret Base.

After your first underground visit, come back and speak to the Underground Man to complete more tasks and get rewards.

Grand Underground

The Grand Underground can be explored at time from now on, with more Pokémon appearing in each Pokémon Hideaway as you earn Gym Badges and collect new TMs. Wild Pokémon levels scale with your number of Badges, starting at Lv. 16-20 with one badge. In addition to the main encounter table, each hideaway has rare spawns that appear at fixed rates independent of the main table. You can also dig in the walls of the tunnels to uncover fossils and other treasures. Of interest, the Skull Fossil (Cranidos) is more common in Pokémon Brilliant Diamond and the Armor Fossil (Shieldon) is more common in Pokémon Shining Pearl.

Spacious Cave

Spacious Cave is the most common cave type, characterized by its plain rocky walls. It is home to a variety of cave-dwelling Pokémon, including Zubat, Geodude, and Machop. In Pokémon Brilliant Diamond, Murkrow can be found here, making it a good opportunity to catch this rare Dark/Flying-type Pokémon. Of interest, Munchlax becomes available after obtaining TM97 (Defog).

Grassland Cave

Grassland Cave has a lush, bright appearance and is home to Grass-type and Bug-type-type Pokémon. Roselia, Combee, Cherubi, and Wurmple can be found here from the start. Silcoon is exclusive to Pokémon Brilliant Diamond while Cascoon is exclusive to Pokémon Shining Pearl.

Fountainspring Cave

Fountainspring Cave is a water-themed biome with spring pools, home to several Water-type Pokémon. Psyduck, Buizel, Shellos, and Gastrodon (West Sea variants) can all be found here from the start. Notably, Gible becomes available after earning the Icicle Badge, making this a cave to return to for the Garchomp family.

Rocky Cave

Rocky Cave is a rocky, barren biome home to Ground and Rock-type Pokémon. Geodude, Onix, and Skorupi can be found here from the start. Bronzor becomes available after obtaining TM96 (Strength), and Hippopotas unlocks after obtaining TM97 (Defog).

Swampy Cave

Swampy Cave is a dark, humid biome featuring Poison-type Pokémon. Zubat, Roselia, Skorupi, and Croagunk are available from the start. Croagunk is a Poison/Fighting-type Pokémon not easily found elsewhere at this point, and it evolves into Toxicroak at Lv. 37.
