Mossdeep City: Pokémon ORAS Walkthrough (Part 16)

Quick Guide

1. Surf past Route 124 to reach Mossdeep City.
2. Challenge the city’s Gym Leaders, Liza and Tate, to earn the 7th Gym Badge.
3. Upon receiving HM07 Dive from Steven, surf toward Route 128.

Route 124

Route 124 is a water route that connects Lilycove City to the west, Route 126 to the south, and Mossdeep City to the east.

Despite having multiple diving spots in the route, you won’t be able to access any of them until you get HM07 Dive. So for now the only option thing to do is to visit the Treasure Hunter’s House.

But your next destination is Mossdeep City to the east, which is the location of the next Gym.

In the middle of Route 124 you’ll find an island cabin known as the Treasure Hunter’s House.

Inside, you can trade one colored shard for a corresponding Evolution Stone (Fire, Water, Thunder, and Leaf).

Here’s the full list of shards that can be traded for Evolution Stones:

East Exit to Mossdeep City

Keep surfing east on Route 124 until you reach the beaches of Mossdeep City.

Then walk east for a bit, and you’ll eventually find the stairs that lead to the main island of Mossdeep City.

Mossdeep City

Mossdeep City, home of the seventh Gym, is a large island situated on the northeast side of Hoenn.

One of the major locations in the city is the Mossdeep Space Station, but this area won’t become relevant until the Delta Episode in the post-game.

To continue with the main story and challenge the Mossdeep City Gym, head to the north side of the city.

Special Secret Bases

Southeast of the Pokémon Center is an old man’s house. The man inside introduces himself as a former Secret Base Expert.

If you look around inside you’ll see there’s a closed backroom door. If you scan a special QR Code in your Secret Base PC, the door in this house will open, revealing a special Secret Base.

One of the QR Codes you can scan is for Shigeru Ohmori’s Secret Base, the Game Director of ORAS. If you talk to him inside his base, you can get a unique Regice Doll decoration for your Secret Base. Below is the QR code to scan for this:

Mossdeep City Gym

Liza & Tate, Mossdeep City’s Gym Leaders both specialize in using Psychic-type Pokémon.

After you defeat them, you’ll receive the Mind Badge and TM04 Calm Mind. Additionally, you’ll be able to use HM07 Dive outside of battle.

Obtaining HM07 Dive + Devon Scuba Gear

As you leave the Gym, a cutscene will trigger.

Steven will approach you and invite you to his house. When you go back with him, Steven will give you HM07 Dive and the Devon Scuba Gear Key Item.

These items enable you to explore underwater trenches, which appear as darker sections on the water, scattered across Hoenn’s seas.

South Exit to Route 127

After talking with Steven, you’ll learn that you need to go to Seafloor Cavern next.

Leave the city through its south exit, surfing onto Route 127.

Route 127

Route 127 is a water route that’s connected to both Route 126 and Route 128. Similar to those routes, it features a long network of underwater trenches you can explore using HM07 Dive.

These underwater areas contain various hidden items and trainers you can battle.
