WHERE & HOW TO FARM
Where to farm
Adventure → Bygone Phantasm; use the current floor, first-clear reward and weekly ranking panels.
Bygone Phantasm is a solo progressive-floor activity with separate first-clear rewards and weekly ranking rewards. Its floor reward track includes Booster Modules, which are used to enhance armor. Open Adventure → Bygone Phantasm, check your current floor, unclaimed milestones, and the next displayed reward, then attempt floors while your build can clear them. Use the mode’s current floor preview and any recommended weapon information shown in the activity. When a Booster Module milestone is reached, claim the reward and use the modules on the armor slot you planned. Weekly ranking rewards are a separate pool, and the mode’s weekly reset adjusts floor progression; check the panel after reset for your current position and reward status. Continue only toward unclaimed progression or current weekly ranking rewards.
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.
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.
Farming tips
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.
