Weapon and Valkyrie materials
Sweep a cleared Material Event stage
Use Sweep to collect eligible Material Event rewards from a stage you have already cleared with three stars.
WHERE & HOW TO FARM
Sweep a cleared Material Event stage
Supplies > Material Event > a stage you have previously cleared with three stars.
Before you go
- Access to the selected Material Event stage.
- A three-star clear recorded for that exact stage.
- An available daily Sweep attempt and a defined need for its listed reward.
Farming steps
- Open the relevant upgrade screen or inventory and decide which material you want to collect.
- Navigate to Supplies > Material Event and check the current stage rewards.
- Choose the stage that displays the target item, not merely a similar reward type.
- Confirm the stage has a three-star clear and that Sweep is available.
- Select Sweep and review the attempt cost and reward preview.
- Run the Sweep, collect the reward, and verify the item count in inventory.
- Repeat only while the stage remains a good match and daily attempts are available.
- Save a stage’s three-star clear for items you expect to need again; it makes later eligible collection quicker.
- Unused daily opportunities refund Planeroids, so consider saving attempts when none of the available stages fits your need.
Repeat, collect and use
Repeatable within the daily Sweep limit for an eligible stage. Unused daily opportunities refund Planeroids; this is not an unlimited run source.
Common mistakes
- Trying to Sweep an uncleared or non-three-star stage: complete it manually and earn three stars first.
- Using attempts without checking the item: inspect the reward panel before each collection session.
- Assuming every unused attempt is wasted: unused daily opportunities refund Planeroids under the Material Event rules.
When to stop or switch
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.
