The Pokémon World Tournament is a facility south of Driftveil City that stands on the former Cold Storage site. Famous Pokémon Trainers from around the world gather here to compete against one another. Outside the building, several vendors stand ready to teach new moves to the competitors' Pokémon. To the west, the north side of the Relic Passage can be found.
The man in the easternmost booth teaches a special move to any members of the starter Pokémon families. Grass-type Pokémon like the Snivy family can learn Grass Pledge, Fire-type Pokémon like the Tepig family can learn Fire Pledge, and Water-type Pokémon like the Oshawott family can learn Water Pledge. Using these moves on the same turn in a Double or Triple Battle will raise their power to 150, and activate additional effects.
Creates a sea of fire where all non-Fire Pokémon lose 1/8 of their max HP every turn for four turns
Creates a rainbow that doubles the likelihood of a move's additional effect(s) for four turns
Creates a vast swamp that reduces the opponent's Speed by 50% for four turns
World Tournament building
Hugh and Clay are waiting outside the PWT building. When you approach, the Gym Leader proudly guides the two of you into the elaborate tournament hall. Inside is Cheren, who was busy investigating something when he was strong-armed by Clay into participating. Follow him and Hugh north to register in the tournament.
Three consecutive victories are needed to win the Driftveil Tournament. The use of items is prohibited during the tournament, so hand out items to your Pokémon before registering. Opponents are not usually decided ahead of time, but for your first tournament, you will need to defeat Hugh, Cheren, and Colress.
After earning 1 BP for winning the tournament, Roxie comes and tells that she will join the tournament. Clay thanks us for making Driftveil City popular and then leaves. Now head outside to see Team Plasma members passing by the building. Colress tries to stop Hugh from chasing them, but he doesn't listen, and follows them south to the pier. Rest up before following him.
A large ship is moored at the pier. Go with Hugh and Cheren to storm the ship, which turns out to be Team Plasma's base of operations. The three of you are immediately surrounded by a crowd of Grunts. Defeat the first two on your own, then team up with Cheren then Hugh to take out the others.
Zinzolin, one of the Seven Sages, emerges from the ship and declares that Team Plasma will rule Unova. He calls the Shadow Triad to appear, and they whisk the three of you off of the ship. Hugh runs off in a huff, and Cheren sets out for Route 6.
The Relic Passage is a large underground cave that was only recently discovered. It connects the Pokémon World Tournament and the Castelia Sewers. One of the tunnels leads to the lowest floor of the Relic Castle, buried deep under the desert sands. The dust clouds that randomly pop up not only give you a chance of encountering a wild Drilbur or Onix, but it also gives you a chance of acquiring a random colored shard. This can help with collecting the shards you need to trade in to a Move Tutor for your Pokémon to learn any compatible move they offer.
Speak to the Worker near the entrance to add a new Funfest Mission, Find Treasure!, to the Entralink. Follow the tunnel eastward, then north to reach a Protein near Backpacker Randall. Battle Hiker Keith in the southeast, and step through the opening in the wall to reach the middle chamber.
Go south to reach a small lake. A Big Pearl lies on the lake's west side, while a Blue Shard is hidden in a rock to the south, and a Max Repel hides in the dead-end path to the southeast. Continue eastward to fight Psychic Tully, and check the nearby rock for a Green Shard. Head northeast to battle Psychic Ena, then check the rock here for a Red Shard. Move the boulder out of the way, and walk through the northeast opening to reach the Relic Castle.
The lowest floor of the Relic Castle consists of five rooms connected in a row, plus a sixth room north of the middle room. Visit the easternmost room to get an Ultra Ball, and check the center room for a hidden Sun Stone. The north room is home to the Bug/Fire Pokémon Volcarona. If you defeat Volcarona, it will respawn when you enter the Hall of Fame again.
Head southwest to fight Backpacker Annie, and check the rock near her to find a Yellow Shard. Turn east and climb the stairway to reach the south chamber.
Go southeast and move the boulder over to the hole in the ground. Head north through the long tunnel to reach a small room in the middle chamber, where an Ultra Ball, Rocky Helmet, Rare Candy, and hidden Rock Gem can be found. Return to the boulder and jump the first ledge to the west to reach a Max Repel. Jump the last ledge and head east; this part of the passage was accessible when you first reached the Castelia Sewers. An Escape Rope lies north of Scientist Terrance, and a Hard Stone sits to the west of Scientist Lumina. Head south to exit through the sewers.
