WHERE & HOW TO FARM
Investigation License rewards from Hollow Zero
Hollow Zero mode menu; choose an unlocked exploration zone and access the Investigation License reward track.
Before you go
- Unlock Hollow Zero at Inter-Knot Level 25, after Certified Proxy promotion and Side Mission The Zero Zone.
- Have an unlocked zone available to run.
- Check current License progress and unclaimed rewards.
Farming steps
- Open Hollow Zero and inspect your Investigation License progress.
- Choose an unlocked exploration zone that your current team can clear reliably.
- Complete the zone through its encounters and final objective.
- Return to the License screen and check whether experience advanced the track.
- Claim every reward milestone now available.
- Review current progress and any remaining weekly limit shown by the interface.
- Run another zone if License progress and desired rewards remain.
- A reliable clear is practical when the goal is License progress; a difficult zone is unnecessary unless its other rewards matter to you.
- Replays can still grant License experience, so check the License track after a repeat run.
Repeat, collect and use
Hollow Zero runs can be repeated and grant Investigation License experience, but License progression is subject to its current reward limits. Repeat while useful progress remains; claim milestones as they unlock.
Common mistakes
- Assuming a run’s rewards are claimed automatically; open the License track and collect them.
- Stopping after one clear when License experience remains available; verify progress before switching modes.
- Treating this as a Battery Charge material stage; Hollow Zero is a separate exploration mode.
When to stop or switch
Stop when the desired License rewards are claimed or the current progress limit is reached; switch to other Hollow Zero objectives if available.
