Zero Cell Sector
Overview
Zero Cell Sector is a post-story Chapter 1 farming hub for characters at Base Level 260 or higher. Its four sectors are divided into two progression tiers: Lux and Nox are the Level 260 entry areas, while Vita and Ark are the Level 270 advanced areas.
After the prerequisites are complete, Robin opens a one-time investigation that unlocks Zero Cell. Newt then provides the temporary authorization required to enter and re-enter the sectors.
Prerequisites
- Reach Base Level 260.
- Complete Bring Down the Air Fortress, the final phase of the Chapter 1 main story.
- Complete A Hazy Gate.
A Hazy Gate is a prerequisite for Robin's Zero Cell investigation. The Rubiel and Minuel services described in that side quest grant access to other post-story regions; they do not replace Newt's Zero Cell authorization.
