Players will see a set of stairs which goes underground in the middle of the room, locked by a cover. In order to unlock it players will need to find 4 spheres on the walls and stand near them to feed them energy until they are fully charged. Each sphere requires 40 energy to be fully charged. A sphere will stop draining energy and glow when charged. When all 4 spheres are charged, the stairs will become unlocked.
- This test is timed. Spheres will revert to their uncharged state if too much time passes.
- The spheres can charge with a Tenno Operator's Void energy, which actually regenerates faster than it is drained
This test rewards 
Power Drift.
