OS Occupation is an Episode 17.1 military sweep instance inside the Occupation Site facility. Your party clears seven sectors of mutant enemies alongside Rebellion forces. The story run features a radio communication mechanic for choosing how to coordinate with other teams. The daily repeat is a straight seven-sector sweep ending in a boss fight.
💡This is an endgame instance tied to Episode 17.1. Two versions exist: a story run (quest 12452) and a daily repeat (quest 12454). The boss at sector 7 hits hard -- bring a healer.
Requirements
| What | Details |
|---|---|
| Pre-quest | Quest 12452 (story run) or quest 12454 (daily) |
| Party | Recommended -- sector sweeps are faster in a group |
Enter through the OS area story or daily trigger.
The instance uses two separate entry triggers inside the OS facility map (1@os_a):
- Story entry -- at (30/352), available once quest 12452 is active
- Daily entry -- at (335/34), available once quest 12454 is active
The story version is triggered as part of the Episode 17.1 main quest. The daily version becomes available after completing the story run.
Story mode: coordinate with other teams via radio.
In the story run you are part of a multi-team operation. As you fight through the facility, radio messages appear asking how to respond to other teams' requests. Choose your responses -- they affect the story dialogue and relationships with NPCs but do not change the combat outcome.
Work through the facility alongside the story NPCs toward the boss sector.
Daily mode: sweep all seven sectors in order.
In daily mode, seven sectors are marked on the map. Clear them in order from sector 1 to sector 7. Each sector contains "CP grade" mutant mobs -- stronger mutants classified by their combat potential grade.
💡Sector mobs hit harder than normal field mobs. Keep your healer topped up between sectors -- there is no rest point between them.Defeat CP7 Miguel at sector 7.
The final sector boss is CP7 Miguel. He is a high-grade mutant commander.
| Boss | Level | Notes |
|---|---|---|
| Miguel | 115 | Periodically summons companion mobs; summons 8 mobs in all directions when HP drops below 30% |
Focus CP7 Miguel down quickly once he reaches low HP to prevent the 8-way mob summon from overwhelming the party. Kill the companion summons if they get in the way.
Collect rewards from the Operation Officer.
After clearing the instance, return to the Operation Officer NPC to collect rewards.
Story run rewards:
300,000 Base EXP + 300,000 Job EXP
Mysterious Component -- 5 components
1x Cor Core (from the Est encounter)
Daily run rewards (via Operation Officer):
150,000 Base EXP + 150,000 Job EXP
Mysterious Component -- 5 components
1x Cor Core
Notes
- Two versions. Story is a one-time run. Daily is repeatable and provides consistent Mysterious Components and Cor Cores.
- Radio choices are cosmetic. Your radio responses in story mode affect dialogue only -- they do not change rewards or combat.
- Miguel's burst summon is deadly. When CP7 Miguel drops below 30% HP he summons 8 mobs simultaneously. Clear space and burst him down before that threshold.
- Sector order is fixed. Daily mode requires clearing sectors 1 through 7 in sequence. You cannot skip ahead.
