THE RIGHT PATH — ENERGY BLOCK PUZZLE

Each block has a pillar nearby. Use Axiom Force to move the block into the square slot on the pillar, then hit the pillar with Force Palm to drive it in.

BOSS: TENEBRUM
Tenebrum appears as a gaseous entity. Regular attacks deal NO damage — this is a pure mechanics fight.
Strategy: Climb the pillars around the arena, jump toward the boss, and use Force Palm in mid-air to strike it. This is the only way to deal damage.

After defeating Tenebrum, you receive a key to the Star Tower. Pick up the Abyss Artifact next to the Dean.
