BOSS: Gym Leaders Liza & Tate

Pokémon: Solrock Lv. 45 (Rock/Psychic), Lunatone Lv. 45 (Rock/Psychic)

Tips
  • This is a Double Battle. Solrock uses Sunny Day, Rock Slide, Psychic, and Solar Beam. Lunatone uses Light Screen, Psychic, Hypnosis, and Calm Mind.
  • An opening turn Surf or double-Surf is highly effective, especially if unblocked by Light Screen.
  • If the initial Surfs don't KO, repeat them on the second turn.
  • Multi-target moves like Earthquake or Bulldoze can be useful, especially with Gravity or Mold Breaker.
  • Dark-type Pokémon like Absol/Mega Absol are strong counters.
  • Banette (Ghost-type) can use Sucker Punch on Solrock.
  • Grass-types can work, but be cautious of Psychic attacks one-hit KOing them. Breloom may need to be higher-leveled.
  • Bug-types are viable; focus attacks on Solrock first to avoid its Rock Slide.
  • The Mind Badge allows all traded Pokémon up to Level 80 to obey you and enables the use of HM Dive outside of battle.
  • TM04 (Calm Mind) boosts Sp. Atk and Sp. Def by one stage.
