Part 5: Getting Started – First 10 Minutes in v4.0

Once you have the update running, the game immediately shows you it is different.

  2. Minimum Grinding Mode: Select YES here. This automatically gives all Pokémon max IVs and allows you to toggle EVs on/off. It saves hundreds of hours.
  3. The Starter: You are not stuck with Charizard, Blastoise, or Venusaur. You can pick almost any starter from Gen 1 to Gen 9, including Hisuian variants.

Pro Tip for v4.0: Immediately catch 6 Pokémon. The first gym (Brock) now has a Level 15 Lycanroc (Dusk form) and a Tyrunt. If you don't have a Water or Grass type, you will lose.
