Tips

• The guard blocking the cave leaves after you help Celio finish the Network Machine on One Island, so finish the Ruby and Sapphire quest first.
• Mewtwo is a static level 70 encounter on B1F; it is Psychic, so Bug, Ghost and Dark attacks are super effective, and Sleep or Paralysis helps a lot (a Master Ball also works).
• Kadabra and Ditto are the most common finds on B1F, Parasect, Golbat and Magneton fill the upper floors, and Wobbuffet is rare everywhere.
• Version differences are only in the water: FireRed has Psyduck and Golduck, while LeafGreen has Slowpoke and Slowbro; Rock Smash gives Geodude and Graveler in both.
• Pick up Full Restore (1F, 2F), Max Revive, Max Elixir, PP Up, Nugget and several Ultra Balls in the corners.
