After a long trek through Victory Road, you finally reach the Pokémon League, where you will battle the Elite Four and the Champion.
Use the Pokémon Center
When you enter the Pokémon League area, you find a Pokémon Center near the entrance. You can fly back to this pokémon center at any time, so feel free to fly elsewhere in Kalos to get ready for the battles ahead, then fly directly back to the Pokémon League when you're ready.
Elite Four Overview
The Elite Four are the four strongest trainers in Kalos, second only to the Pokémon League Champion. Your goal now is to become the new reigning Champion of Kalos by defeating the Elite Four and the current Champion.
Once you enter the Pokémon League building, you can only leave if you become the Champion, or if you are defeated (but don't worry: you can try again as many times as it takes). That means that you have to use the same six pokémon in all of the upcoming battles; you won't be able to go to the PC Box to switch different pokémon into your party between battles! You will have to choose your pokémon carefully.
Each member of the Elite Four focuses on a specific type, much like a gym leader. In the Kalos Pokémon League, one of the Elite Four has Water-type pokémon, another has Fire-type pokémon, another has Steel-type pokémon, and another has Dragon-type pokémon.
Enter the Pokémon League
When you're ready, go north from the Pokémon Center to enter the Pokémon League building.
Inside the building, you can go left or right. It takes you to the same place. In the next room, use the doors in the west wall and east wall to reach the chambers of the Elite Four. The northeast door goes to the Blazing Chamber, where you will face Fire-type pokémon. The southeast door goes to the Flood Chamber, where you will face Water-type pokémon. The northwest door goes to the Ironworks Chamber, where you will face Steel-type pokémon. The southwest door goes to the Dragonmark Chamber, where you will face Dragon-type pokémon.
After you defeat all four of the Elite Four, a door will open in the north wall of the main room. Go through this door to enter the Radiant Chamber, where you will face the Champion.
