WHERE & HOW TO FARM
Where to farm
The qualifying boss route for the blueprint you are missing, with the required Boss Stem Cells active in the run.
Some boss blueprints are tied to Boss Stem Cell progression. The active BSC level affects which routes and unlocks are available, so identify the specific boss and requirement before planning a run. Boss access alone does not guarantee that a blueprint remains uncollected. After securing a blueprint, cell payments at the Collector are still needed to unlock its gear.
Unlock and activate the BSC level required for the target.
Know which boss is associated with the missing blueprint.
Avoid Aspects when pursuing the next Boss Stem Cell unlock.
Check your missing unlocks and select a boss blueprint as the target.
Confirm the required BSC level and the route that reaches that boss.
Set the required number of cells in the starting tube before leaving.
Follow the chosen route and use BSC doors only when their displayed requirement is met.
Reach the target boss and defeat it; collect any blueprint drop that appears.
At the next Collector, pay the blueprint’s cell cost to make the gear available.
If the blueprint is not awarded, review whether it is still missing and whether the correct boss and BSC condition were used.
Farming tips
Higher BSC than the minimum does not create extra sequential boss blueprint drops; pursue the next required step in order.
Keep the boss and route requirement written down before a long run so you do not finish the wrong branch.
Repeat, collect and use
Repeatable until the target boss blueprint is collected. Each blueprint is a one-time unlock; BSC progression itself advances through specific boss victories.
Common mistakes
Following a route that does not reach the named boss; map the route before starting.
Using an Aspect while attempting to earn the next BSC; leave Aspects off for that progression goal.
Assuming a blueprint drop is already unlocked; verify the Collector list and spend cells after collection.
When to stop or switch
Stop this route when the target blueprint is collected and paid for, or switch to the next boss requirement in the sequence.
