Tips
- Tate and Liza use Lunatone L42 and Solrock L42 in a Double Battle. Water, Grass, Dark and Ghost moves work well; bring at least two Pokémon.
- After the Mind Badge, visit Steven's house for HM08 Dive.
- After the Hall of Fame, a Beldum (L5) waits in Steven's house; you need a free party slot.
- A Fisherman in the house east of the Gym gives you the Super Rod.
- A boy outside Steven's house gives you a King's Rock, and you get a Sun Stone at the Space Center.
- Super Rod fishing here finds Sharpedo (L30–35) at a 40% rate.
