Location: Spear Pillar (Coronet Highlands)
Strategy: Depending on your choice, you'll face either Dialga or Palkia first. Both battles are similar to Noble encounters but with increased difficulty. They have powerful signature moves that cover large areas. Focus on dodging and throwing Balms during their vulnerable moments. After quelling the first legendary, you'll then battle the other in a traditional Pokémon battle. Ensure your team is high-leveled and has type advantages (Fighting/Ground for Dialga, Dragon/Fairy for Palkia).
