Chapter 4: The Expanse (Sol Valley, Flare Pool)

Upon entering Sol Valley, MacKenzie will inform you of three more Teleporter Keys, with the volcano in the southeast being your primary destination.

Locate the Ring of Thunder Shrine, halfway between Chrono Tower and the volcano entrance. Go around the back to find a Psychic Crystal, pull it down to reveal an ENERGY TANK (4/14).

At the south central edge of the map, find a natural rock structure resembling a needle's eye. Boost up the ramp and aim for the hole to hit a MISSILE EXPANSION (7/48).

In the north central G.F. Debris, enter the western structure from the west. Break the boxes inside to find a MISSILE EXPANSION (8/48).

Proceed southeast to the volcano's entry point. Use Projectiles on the Sand Shren Hives outside the entrance on the left wall.

Enter the Vi-O-La Spinner, rev it up, and enter Flare Pool.

In the southern lava pool (to your right) within the Volcano Entrance area, scan the Psychic energy to create Platforms. Hop up them to reach a MISSILE EXPANSION (9/48).

Proceed east to Magma Overflow and continue to Shoreline Access. Note the turned-off door on your right.

Continue past the trucks to Lava Lake Bridge. Use the Vi-O-La Spinner to extend the broken bridge, but you cannot cross yet. Head back.

As you approach the side door at Shoreline Access, three Psy-bot Soldiers will emerge. Use Projectiles from your Vi-O-La to defeat them.

Enter the door and proceed through Scrapyard Access, noting the Save Station.

In the Scrapyard, watch out for Pyremites on the lower ground. Use platforms to avoid their explosive attacks.

To reach the plasma torch, get on the back platform using the stacked canisters behind the torch crane. Roll into the framework and bomb the obstruction.

Roll to the front and bomb the torch off. Drop down and take the FIRE CHIP.

Retrace your steps out of Flare Pool. As you leave Magma Overflow, the pipe behind you will burst, blocking passage with magma.

Return to Fury Green in the middle of the west side of Sol Valley via the natural rock arch entry. Lay waste to the three Sand Shren Hives with your projectiles before exiting your bike.

Proceed through Ancient Aisle to the Cargo Launcher to Temple of Memory. This acts as a warp point near Base Camp.

Before leaving the Cargo Launcher area, look left (east). Hop onto the fallen structure where Psychic Platforms are visible. Make them solid and hop across to a MISSILE EXPANSION (10/48).
