WHERE & HOW TO FARM
Lost Sector exploration for Harmony Cube rewards
Ark > Lost Sector.
Before you go
- Unlock a Lost Sector area through Campaign progression.
- Bring a squad capable of handling the sector’s encounters.
- Have time to explore the displayed map and route mechanics.
Farming steps
- Open Lost Sector and choose an unlocked area that is not fully cleared.
- Review the map and identify visible paths, obstacles, switches, and unopened routes.
- Move through the sector while engaging enemies that block progress.
- Interact with route devices and environmental mechanics as they appear to open paths.
- Search accessible branches for caches and collect their displayed rewards.
- Complete the remaining route and verify the sector’s clear status and reward record.
- Use earned cube-related items through the relevant progression menu when available.
- Recheck branches after using a switch or route device; newly opened paths can lead to missed caches.
- Use the sector’s visible mechanics as the route guide instead of treating it as a straight combat stage.
Repeat, collect and use
Each sector is a one-time exploration clear for its caches and completion rewards. Repeat only to finish missed areas or when Campaign progress unlocks another sector.
Common mistakes
- Rushing past side paths; inspect branches for caches before advancing.
- Leaving route devices unused; interact with the visible mechanisms when progression stalls.
- Expecting a cleared sector to produce recurring drops; move to a newly unlocked area for fresh exploration rewards.
When to stop or switch
Stop when the sector is marked complete and its accessible caches are collected; return after unlocking another area or identifying a missed branch.
