Overview
- Walkthroughs confirm the underground 3x3 button grid must have all tiles pressed, with a five-press solution such as Top-Middle, Middle-Left, Top-Left, Bottom-Right, Center.
- Back at the dome, players use Axiom Force to position four cube batteries by the pillars and Force Palm each one into its slot to power the device.
- Once activated, the portal destabilizes, requiring Axiom Force to pull the glowing unstable core free before the situation escalates.
- After Octavius is pulled into the portal, the Tenebrum encounter is taught as a tutorial: use Blinding Flash to reveal weaknesses, stay airborne, and land midair Force Palms when it pauses at center.
- Guides note that selecting “retry” after death can reset progress to the puzzle and detail the next objective at the Spire of the Stars, where Engraved Stones drive a symbol-switch solution to reach the sky islands.
