After defeating Team Rocket at the Radio Tower, go to Blackthorn City and enter the gym. This gym has boulders that can be pushed from the 2F and down into the pools of lava. Once the boulders are all down, you can cross to battle the gym leader. Clair uses Dragon type Pokémon. Dragonair will use Thunder Wave to paralyze opponents. One knows Surf, the 2nd one knows Thunderbolt, and the 3rd one knows Ice Beam. Kingdra will be the hard part as it will use Smokescreen to lower the target’s Accuracy. Since Kingdra is Water/Dragon type, only Dragon type moves have an advantage against it. After the battle, Clair won’t offer anything yet. She will tell you about the Dragon’s Den that you will enter next to find a mysterious shrine. Enter the Dragon’s Den and go into the shrine where an elder will quiz you. After you’re finished with the quiz, Clair will step in to give you the Rising Badge. Once you leave the shrine, Clair will give you a TM24 (Dragonbreath). Dragonbreath has a 30% chance of paralyzing the target.
