WHERE & HOW TO FARM
Unlock Cavern route with two BSC
Two-BSC door in Slumbering Sanctuary leading to the Cavern.
Before you go
- Have unlocked two Boss Stem Cells.
- Activate both cells in the starting tube.
- Reach Slumbering Sanctuary with enough health to continue into a harder branch.
Farming steps
- At the starting tube, select two active Boss Stem Cells.
- Follow a route that reaches Slumbering Sanctuary.
- Explore the biome and locate the door labeled for the Cavern route.
- Read the displayed BSC requirement and confirm the door is available.
- Open the door and enter the Cavern branch.
- Defeat enemies carefully and collect cells or blueprint drops relevant to your goals.
- Reach the next Collector passage and spend carried cells before leaving.
- Two-BSC runs remove passage health fountains, so conserve health and use other healing options carefully.
- A blue-lit eligible door signals that your current active count meets its requirement.
Repeat, collect and use
Repeatable on runs with two BSCs active and access to Slumbering Sanctuary. The route gate is conditional each run; any particular blueprint is a one-time collection.
Common mistakes
- Having two BSCs unlocked but not activated; set both in the starting tube.
- Entering at low health because the gate is available; the branch remains harder and the run can end before rewards are spent.
- Assuming a blueprint will drop again after it is collected; check the unlock list and target a still-missing item.
When to stop or switch
Stop exploring the branch when your targeted reward is collected or your health is too low to justify continuing; spend cells at the next Collector.
