Walse Meteorite to Karnak Meteorite

After the Tower of Walse submerged into the water, you'll reappear just before a meteorite. Enter the meteorite and follow the linear path. Inside, step on the portal to warp to another location (Walse Meteorite -> Karnak Meteorite).

Head west, follow the mountain range up north, then you'll see a forest on your left. Enter the forest, then follow the path south.
You won't be able to enter the castle and the ship though, so let's enter the town first.

Karnak

On the way to Karnak, you'll probably encounter a monster named Wild Nakk. It has a blue magic spell, so you should grab it now. It usually spawns around the Karnak area.
Around the Karnak area, there is another blue magic spell from a monster called Wild Nakk.

Enter Karnak after you get the blue magic.

• Head straight to the Pub and interact with the piano (Piano Maestro achievement - 3/8).
• Feel free to talk to people in the town to learn more about the story.
• Next, enter the Weapon Shop and talk to the staff. You'll find everything is so cheap (about 80% discount), so take this opportunity to buy Frost Rod (useful for our upcoming dungeon) or anything of your choice. Then, you'll get arrested, whether you buy anything or not. After the event, the price will go back to normal.

Karnak Castle

Last chance, this castle will be inaccessible after this.

• You'll reappear inside Karnak Castle's prison.
• Approach the door to trigger a scene.
• Once the scene is finished, follow the map below to leave the castle (all treasures are locked at this point, so we'll have to come back later).

Shopping in Karnak (Highly Recommended)

All shops in Karnak are now unlocked, so I suggest you spend all your money on purchasing all magic spells. Also upgrade your equipment if you have some to spare.

• Fira, Blizzara, Thundara and Cura, Haste, Gravity, Raise are the most important spells you should prioritize buying.
• Buy a dozen Eye Drops because you'll get blinded a lot during your next dungeon.
