Route 9 – Spikes Passage

Level Range of wild pokemon: 15-17

There's a Rhyhorn waiting for you outside so just hop on it and use it to navigate the area. You'll still encounter wild pokemon randomly while riding the Rhyhorn. When you encounter rock boulders, you just need to press A to have Rhyhorn destroy them. After destroying the first boulders along the way, destroy the next one that's blocking the stairs. Get off the and pick up X-Defense.

Continue ahead and once you've reached the split in the path, go to the right first and destroy another boulder blocking some stairs. Get off and pick up a Paralyze Heal. Before leaving, take the narrow path south of the stairs and follow it to reach a Fire Stone.

Return to the main path and destroy more boulders. Go past the NPC on the left and continue to the right side. Destroy the boulder there and disembark from your rhyhorn. Follow the path south to find a Dusk Ball. There's also a Sky Trainer here that you can challenge, provided that you have a pokemon that's capable of flying. (Not just limited to Flying Types)

Sky Trainer Orion (Prize Money: 2,100)

• LV21 Ledian

Backtrack and talk to the lady in red to heal your pokemon back to full health. Check the rock northeast of that NPC to find a Super Repel. When ready, enter the Glittering Cave.
