Mossdeep City

Mossdeep City

Mossdeep City stands perched on an island near Hoenn's eastern edge, where the winds are mild and the weather conditions are stable. This makes it the perfect place for launching rockets, and a perfect home for the Mossdeep Space Center. The seventh Gym in the Hoenn League, run by twin Gym Leaders, is located on the north side of the island, and Steven's house can be found on the island's northwest corner.

Steven's House

The house on the island's northwest edge belongs to Steven, and contains part of his rock collection. He greets you when you step inside, and hands you HM08 (Dive). In certain bodies of water, there are dark spots where the water runs unusually deep; using Dive at one of these spots lets you descend to the ocean floor far below. Swim to a point where the sunlight filters down from above and use Dive again to surface. With this move, you will be able to pursue Maxie^R/Archie^S to the Seafloor Cavern—but you'll need to beat the Mossdeep Gym first.

Running Errands

Visit the house nearest the stairway to the Space Center to meet a young woman who uses a Wingull to send letters to a friend in Fortree City. Talk to the Wingull and it will take flight, off to deliver another note. If you return to Fortree and visit the Pokémon Breeder in the northeast house there, he will give you a Mental Herb that his Wingull found in its travels.

Score the Super Rod

The house overlooking the Gym belongs to a lone Fisherman. Speak to him to receive the Super Rod, a high-end fishing rod that can reel in all kinds of sea life.

Mossdeep Space Center

The Mossdeep Space Center stands on a hill in the northeast. A Sailor near the viewing area will give you a Sun Stone he found on the beach.

Mossdeep Gym

Mossdeep Gym

Mossdeep City Pokémon Gym
Leaders: Liza & Tate
The mystic combination!

The Mossdeep Gym specializes in Psychic-type Pokémon, which are vulnerable to Bug-, Dark-, and Ghost-type moves. Dark Pokémon are both immune to Psychic moves and able to inflict super-effective damage. Avoid using Fighting- and Poison-type Pokémon. The Gym features a series of spin tiles and several switches; when flipped, these switches alter the direction of the red tiles, allowing challengers to progress to the twin Gym Leaders.

Go northwest from the entrance and flip the switch; this redirects the red tile to the left. Walk north onto the arrow tiles, which lead west to a battle with Psychic Preston. Go west to slide north and east to the second red tile, which diverts you to a battle with Psychic Maura. Head north to fight Psychic Samantha and flip the nearby switch; this redirects the second red tile. Go back south, then south from Psychic Maura to the entrance. Follow the arrow tiles on the right to the third red tile, and a battle with Psychic Fritz. Flip the switch to redirect the red tile, then go northeast to slide around to a small clearing near Psychic Maura. Head south to slide around to the northwest and flip the final switch near Psychic Virgil to redirect the fourth red tile. Go south to slide back to the entrance, and take the left path once more to reach the Gym Leaders.

Twins Tate and Liza send out two Pokémon at once, drawing challengers into a Double Battle. Lunatone can lull its opponent to sleep with Hypnosis, while Solrock can scorch Grass Pokémon looking to target their Rock typing. Both of their Pokémon are weakened by Water moves; by using Surf, you can attack both at once and bring the battle to a quick end. Otherwise, you may want to target one Pokémon at a time in what would essentially become a two-on-one battle.

High tide

Entrance

An old man in the entry chamber offers to make a Shell Bell for your Pokémon. But first, he needs you to collect some of the cave's natural resources: Shoal Shells and Shoal Salts. These items are replenished each day, so there's no limit to the number you can collect. Once you hand over four of each item, he crafts the health-restoring item for you. Surf northwest and take the doorway there to reach the next chamber.

Second Cavern

Surf along the water in a clockwise direction, collecting the four Shoal Shells and a Rare Candy on the way. Take the southeast doorway back to the entrance, where you can collect a Big Pearl on the nearby ledge.
