Collect mode-contained cells and convert them into permanent progression before leaving.
Boss Rush entrance in Prisoners’ Quarters; the spending point is at the end of the selected trial.
Boss Rush offers a compact sequence of boss fights with cells earned for that mode. Those cells do not transfer to a normal run, so the useful farm is the complete loop: choose a trial, defeat its bosses, then spend the resulting currency at the end-of-run Legendary Forge or Collector. Treat the mode as a self-contained session.
Repeatable while Boss Rush trials are available. Cells are earned within each run and must be spent there; Forge progress and Collector unlocks persist.
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.
