Rising Badge - Gold in the Dragon's Den

Blackthorn City: Upon arrival, heal and shop. Visit the Move Deleter in the house southwest of the Pokémon Center to change moves (e.g., replacing Surf with Waterfall on Gyarados). In the house near the Ice Path, you can trade a Dragonair for a Rhydon, though this is generally not recommended.

Blackthorn City Gym Entrance: Head to the Gym in the north-central part of the city.

Gym Puzzle - 1F: Enter the Gym, head northwest to battle a Trainer. Go north to the stairs. On the upper floor, go southeast and battle another Trainer. In the southeast corner, push the eastern boulder south, then maneuver behind the other boulder and push it north into a hole. Continue north, defeat the Trainer. To the east, push the nearest boulder all the way east, then push the other boulder into the hole.

Gym Puzzle - Return to 1F: Go back south towards the first hole and descend the stairs to reach the first floor again.

Gym Battle - 1F: Defeat the nearby Trainer. Cross the Strength boulder and head north to find another Trainer. After defeating them, cross the next boulder.

Gym Leader Clair: Speak to the girl on the platform – this is Gym Leader Clair, the eighth and final Gym Leader of Johto.
