Pokémon Battle Tips

  • Super Effective: Always prioritize moves that deal 2x or 4x damage
  • Resistances: Avoid 0.5x moves; switch to a better matchup
  • Immunities: 0x moves are useless; change strategy immediately
  • Dual Types: Multipliers multiply (0.5x × 0.5x = 0.25x)
  • STAB: Same-Type Attack Bonus adds 1.5x to matching moves
