If you’re in the dark chamber with colored lenses, mirrors, and a central object, clear the dust with the blue beam, then route green, red, and blue light to their matching switches. If a shared lens blocks blue, reroute red while keeping its switch lit. Once all three switches glow, use the pedestal that appears to claim the symbol.
First, identify which Chapter 5 trial you’re in
“Last symbol” can refer to different trials because Chapter 5’s four trials can be completed in different orders. In a dark underground room with colored lenses and mirrors, follow the light puzzle below. If instead you’re facing spike tiles and a patterned floor, use the sequence Dots → Squid → Dots → Flower → Squid, as listed in the AllThings.How Chapter 5 guide.
Reach the colored-lens chamber
- Follow the tree-lined hallway to the locked metal door.
- Turn around, climb the ladder, and crawl through the opening in the rocks.
- Activate the light pillar on the upper ledge, then descend into the chamber.
Clear the lenses and mirrors
Start with the blue projector. Sweep its beam around the chamber to burn away dust covering the lenses and mirrors. Then check the red lens and clear any remaining dust in its path. Dust can obstruct a route even when the beam is aimed correctly, so clear the optical surfaces before working out the final beam paths.
Light each matching switch
Route green first
Use the green lens and mirrors to send green light to the green-outlined switch on the central object.

Set the red route
Aim red light through the available mirrors at the red-outlined switch. Keep in mind that some lenses are shared between beam paths.
Finish with blue
Direct blue light to the blue-outlined switch. If blue cannot reach it, revisit the red route: move red to another valid path that still keeps the red switch lit and frees the lens blue needs. The goal is not to preserve one fixed sequence of mirror positions, but to have all three matching switches lit at once.

The chamber combines two tasks: removing dust that blocks light and arranging beams through lenses and mirrors. Because routes may share lenses, a beam that worked earlier can need to move when you set another color. Use the switch outlines as your targets, and judge progress by whether all three colors remain lit together.
