Route plan

The clean route is Card Key first, then key item/item sweep, then Rival on 7F, then Giovanni on 11F.

Route Notes

  • Warp tiles are easier if you treat each floor as an item sweep after Card Key rather than a blind maze.

  • Review boss cards and heal before any Rival, Gym Leader, Rocket Admin, Elite Four, Champion, or legendary encounter listed above.
