If you’ve spent any time in Hoenn, you know the drill. You beat the seventh Gym Leader, you surf across the water, and suddenly you’re stuck in a maze of warp tiles and angry grunts wearing hoodies with horns. The Omega Ruby Team Magma Hideout is basically the peak of villainous architecture in the 3DS era. Honestly, it’s a bit of a headache if you aren't prepared. Most players just rush through to stop Maxie from waking up Groudon, but if you do that, you're leaving some of the best loot in the game behind. I’ve run through Lilycove City more times than I can count, and every time, I see people complaining that they can’t find the Master Ball or they got lost in the basement levels.
It’s tucked away in a cove just east of Lilycove. You need Surf to even see the entrance. Once you’re inside, the vibe shifts from the breezy, trumpeting music of Hoenn to this industrial, metallic grind. It’s cool. It’s also frustrating.
The Layout of the Team Magma Hideout
The first thing you’ll notice is the warp tiles. These are a classic Pokémon trope, but in the Omega Ruby Team Magma Hideout, they’re used with a specific kind of malice. You aren't just walking from room to room; you’re being teleported across floors, often into dead ends where a Grunt is just waiting to throw a Numel at you.
One of the big differences between the original GBA games and this remake is the sheer scale. The 3DS version adds a lot of depth to the rooms. You’ll see submarine parts, magma-drilling equipment, and research labs that actually look like people work in them. Tabitha and Courtney have their own presences here too. If you’re playing Alpha Sapphire, this whole place is just a generic cave for Team Aqua, but in Omega Ruby, it feels tailored to the "land-expansion" obsession of Maxie.
You start on the ground floor. It seems simple enough. There are some crates and a few Grunts. But the deeper you go, the more the "puzzle" elements kick in. You have to find the right sequence of teleporters to reach the lower levels where the "Submarine Explorer 1" is docked.
Don't ignore the side rooms. Seriously. There’s a rest area where you can heal your Pokémon, which is a godsend because you’re going to be fighting a lot of Koffing and Poochyena. If you're running a team that's weak to Poison or Fire, this place can actually be a bit of a grind. Bring Antidotes. Better yet, bring a strong Ground or Psychic type. A well-leveled Gardevoir or Claydol will basically delete everything in this building.
Finding the Master Ball (and why most people miss it)
Okay, let’s talk about the Master Ball. It is the single most important item in the Omega Ruby Team Magma Hideout. If you leave without it, you’ve failed. You can’t come back and get it easily later once the story progresses to a certain point and the hideout gets locked down or changed.
To find it, you have to navigate to a specific room filled with four item balls on the floor. It looks like a trap. Honestly, it kind of is. Two of them are actually Electrode. They will explode. They will hurt. But tucked in that cluster is the Master Ball and a Nugget.
To get there, you need to find the specific warp tile sequence in the room with the massive green floor monitors. It’s usually the tile on the far left of a cluster of three. If you take the wrong one, you just loop back to the start of the floor. It’s a classic "troll" move by the developers. But hey, that's Pokémon.
There's also the TM for Snatch and various Max Revives scattered around. Most players don't care about Snatch, but if you're into the competitive side or just like weird move sets, it’s worth the extra thirty seconds of walking.
The Horde Battle and Courtney
The Omega Ruby Team Magma Hideout features one of the most satisfying—or annoying, depending on your level—moments in the game. The 5-on-1 Horde Battle. You walk into a hallway and five Team Magma Grunts decide to jump you all at once.
If you have a Pokémon with Surf, Earthquake, or Dazzling Gleam, this is the best feeling in the world. You just wipe all five Poochyena in one turn. If you don't have an "all-hit" move? You’re going to sit there for five minutes watching five different animations of Sand Attack or Tackle. It’s a slog.
Then there’s Courtney. She’s the Magma Admin you face here. In the remakes, she has this weird, robotic, almost "alien" personality that makes the encounter way more memorable than the GBA version. She uses a Camerupt. It’s not a hard fight if you have a Water type, but it marks the point where the story starts to get heavy. Maxie is already heading for the Seafloor Cavern. You’re basically playing catch-up.
Navigational Tips for the Basement
The basement is where the submarine is. You’ll see the big pool of water and the sub getting ready to dive. This is your "point of no return" for this specific story beat. Once you reach the end, you’ll fight an Admin to buy Maxie time to escape.
- Check the corners: There are hidden items like Full Restores tucked behind crates.
- Talk to the Grunts: Some of them give you actual flavor text about how much they hate the heat or how they're just there for the benefits. It’s world-building, guys.
- The Healing Room: It's on the middle floor, look for the beds. You don't need to run back to the Lilycove Pokémon Center.
The logic of the Omega Ruby Team Magma Hideout is built on misdirection. The game wants you to take the most obvious path, which almost always leads to a dead end or a fight you don't need. Look for the warp tiles that are tucked behind equipment or in the corners of the rooms. Those are the ones that lead to the Master Ball.
What Happens After the Hideout?
Once you clear the hideout, the submarine is gone. The story moves to Route 128. But the impact of the hideout stays. You’ve likely picked up enough EXP to get your team into the mid-40s or early 50s. You’ve got the Master Ball (hopefully).

People often ask if they should use the Master Ball on Groudon. Personally? No. Groudon has a decent catch rate in this game compared to older titles. Save it for Deoxys in the Delta Episode or a shiny roaming legendary if you have the patience for that.
Actionable Steps for Your Playthrough
If you are currently standing outside the cave in Lilycove, do these three things:
- Empty your bag space or stock up on Ultra Balls. You're going to find some high-value loot and you'll be fighting those Electrodes that you might want to catch for your Pokédex.
- Put a Pokémon with "Surf" or "Earthquake" in your first slot. The Horde Battle is coming, and you do not want to fight five Poochyenas individually.
- Head to the far-left warp tiles first. This is the "secret" path to the Master Ball room. If you find yourself in a room with a lot of computers, you're in the right neighborhood.
The Omega Ruby Team Magma Hideout isn't just a detour; it’s the climax of the mid-game. It’s where the stakes move from "stopping some weirdos in capes" to "the world is literally going to evaporate." Take your time, grab the Master Ball, and don't let the warp tiles give you a migraine. Once you're out, it's a straight shot to the final Gym and the Primal Reversion showdown.
