WHERE & HOW TO FARM
Bygone Phantasm first-clear Booster Module milestones
Adventure → Bygone Phantasm; use the current floor, first-clear reward and weekly ranking panels.
Before you go
- Unlock Bygone Phantasm.
- A build able to clear the current floor and progress to further stages.
- An armor enhancement goal that uses Booster Modules.
- Check current floor and reset information in the live mode panel.
Farming steps
- Open Bygone Phantasm and record the current floor plus the next unclaimed first-clear reward milestone.
- Review the floor’s enemy preview and any recommended weapon information shown in the activity; equip a build you can use reliably.
- Enter the current floor and defeat its enemies to clear the stage.
- After a successful clear, check the reward panel and advance only if the next floor remains manageable.
- Claim a first-clear reward when its milestone grants Booster Modules.
- Use the modules to enhance the planned armor slot, checking the live enhancement costs.
- After weekly reset, reopen the mode and check the adjusted floor position and separate weekly ranking-reward status.
- Booster Modules are armor-enhancement materials, not weapon breakthrough materials.
- First-clear floor rewards and weekly ranking rewards are separate; track them independently.
- Do not rely on a remembered floor threshold: use the current reward panel.
Repeat, collect and use
Continue into unclaimed floors while progression is manageable; check the weekly ranking track again after reset. Already-claimed first-clear rewards are not a repeatable drop.
Common mistakes
- Expecting Booster Modules from every floor rather than the listed milestone rewards.
- Confusing first-clear rewards with the weekly ranking pool.
- Treating a weekly reset as a repeat of first-clear rewards.
When to stop or switch
Stop pushing when the next floor cannot be cleared reliably or the next useful first-clear milestone is claimed; resume after checking the next weekly reset state.
