WHERE & HOW TO FARM
Boss Rush cell and forge run
Boss Rush entrance in Prisoners’ Quarters; the spending point is at the end of the selected trial.
Before you go
- Unlock the Boss Rush entrance.
- Choose an available trial tier you can reliably complete.
- Have a Forge upgrade or Collector blueprint ready as a spending target.
Farming steps
- Enter Boss Rush and review the available trial before committing to it.
- Choose a build color and starting options that fit your preferred boss strategy.
- Fight each boss in sequence and collect the cells dropped during the mode.
- Use the offered opportunities to manage your build and remain ready for the next fight.
- After the final encounter, go to the end-of-run spending area.
- Invest cells in the Legendary Forge to improve future gear quality, or pay a Collector blueprint cost.
- Confirm the purchase before leaving the mode, then repeat with another suitable trial.
- Decide whether Forge quality or a particular Collector unlock matters more before starting.
- A completed trial is useful only if you spend its cells; they are not normal-run currency.
Repeat, collect and use
Repeatable while Boss Rush trials are available. Cells are earned within each run and must be spent there; Forge progress and Collector unlocks persist.
Common mistakes
- Expecting Boss Rush cells to appear in a later normal run; spend them before exiting the mode.
- Entering a trial without a spending goal; decide between Forge and Collector progression first.
- Treating a harder tier as automatically more efficient; use the tier you can finish and cash out consistently.
When to stop or switch
Stop the session when your intended Forge upgrade or blueprint payment is complete, or switch to a more manageable trial if repeated attempts are not reaching the spending screen.
