Use Sweep to collect eligible Material Event rewards from a stage you have already cleared with three stars.
Supplies > Material Event > a stage you have previously cleared with three stars.
Sweep is a repeat option for a Material Event stage after you have earned its three-star clear. It saves you from replaying a stage manually when your goal is to collect more of the same listed reward. First confirm the stage still matches your current material need; a convenient clear is not useful if its reward is wrong. Sweeps consume the activity’s available daily attempts, and those attempts are limited. The game’s Material Event rules also describe a Planeroid refund when daily opportunities go unused, so do not feel compelled to spend every attempt on a poor reward match. Collect the resulting material from the stage rewards and apply it to the upgrade or other planned use. This is a repeatable collection method only while the stage and attempts are available; it does not bypass the stage’s eligibility requirement.
Repeatable within the daily Sweep limit for an eligible stage. Unused daily opportunities refund Planeroids; this is not an unlimited run source.
Stop when you reach the quantity needed for the planned upgrade or when the day’s eligible attempts are gone; preserve remaining opportunities if the listed reward is not useful.
