How the hunt works

Pick a patch of grass where your target has the highest encounter rate, then run in a tight loop so you trigger battles as fast as possible. Check the sprite the moment the battle starts, and run from anything that isn't shiny.

The base rate in Pokémon Sapphire is 1 in 8,192. There is no Shiny Charm in this game, so the base rate is the best you can get.

Tips

  • Repels stop lower-level species spawning, which raises the share of encounters that are your target.
  • Keep a fast Pokémon in the lead so escaping takes one input.
  • Use the smallest grass patch you can — fewer steps between encounters.
