1. Stock Up On Items: Before entering Victory Road, ensure you have a plentiful supply of items such as Potions, Super Potions, and Revives. You can purchase them at the Celadon City Department Store or the Vermillion City Pokémon Center.
2. Team Composition: Your team composition should be diverse and balanced. Have a variety of Pokémon with different types and moves to counter different situations and opponents. Consider bringing Pokémon with strong Physical and Special attacks to deal with different Trainers' strategies.
3. Type Effectiveness: Pay close attention to type matchups. Use Pokémon that have type advantages over your opponents. For example, Electric-type Pokémon are effective against Water-type Pokémon, while Water-type Pokémon are effective against Fire-type Pokémon.
4. Avoid Status Effects: Be wary of Trainers who use Pokémon that inflict status effects like Sleep, Confusion, or Paralysis. These can disrupt your strategy, so consider carrying status-curing items like Awakening or Full Heal.
5. Watch Out For Trainers: Victory Road is filled with tough Trainers, including Ace Trainers and the Elite Four. Be prepared for challenging battles, and plan accordingly by switching your Pokémon and using the most effective attacks.
6. Explore Thoroughly: Victory Road has several hidden items, including TMs and rare items. Don't rush through; take time to explore and collect these items.
7. Focus On Healing: Bring Pokémon with healing moves like Heal Pulse, Recover, or Rest. These will help keep your team in shape during the long and arduous journey.
8. Level Up: If your Pokémon are under-leveled, consider spending some time training them in the surrounding areas or Routes before challenging the Elite Four.
>Tip: The Elite Four consists of four tough opponents, each specializing in a different type of Pokémon. Lorelei specializes in Ice-types, Bruno in Fighting-types, Agatha in Ghost and Poison-types, and Champion Lance in Dragon and Flying-types. Be ready to adjust your strategy based on the type of opponent you're facing.
Remember to be patient, use strategy, and take your time as you make your way through Victory Road. Good luck!
