Resonator Upgrade Materials
Allocate weekly boss claims to Forte materials
Spend limited weekly boss reward claims on the Forte material that is blocking a character you are actively upgrading.
WHERE & HOW TO FARM
Allocate weekly boss claims to Forte materials
Weekly Challenge boss arenas selected through the Guidebook or challenge interface.
Before you go
- Unlock the weekly boss associated with the material you need.
- Have a remaining weekly reward claim and Waveplates.
- Identify the Forte material and character upgrade it will serve.
- Check the week’s remaining claims before choosing a boss.
Farming steps
- Open the Forte upgrade screen for the character you are prioritizing and note the missing weekly boss material.
- Open the Guidebook’s weekly challenge list and inspect available boss reward previews.
- Choose the boss whose listed reward matches that missing material.
- Enter the arena and defeat the boss.
- Before claiming, confirm the remaining weekly claim count and spend Waveplates if the material still advances your plan.
- Record the material received and update the Forte shortfall in your notes or upgrade screen.
- Use remaining weekly claims on other genuinely needed boss materials, then return after the weekly reset if the target remains incomplete.
- A weekly boss can remain fightable after claims are exhausted, but the limited paid reward is the farming resource.
- Choose by upgrade bottleneck, not boss preference; unused claims cannot help a material that is blocking progression.
Repeat, collect and use
Weekly-limited reward claims refresh on the weekly cycle. Additional fights after the limit do not provide the claimed weekly reward.
Common mistakes
- Treating every fight as a material claim: check claim availability before entering for progression.
- Spreading claims across bosses without an upgrade target: prioritize one or two planned Forte upgrades.
- Assuming the reward is fixed to the material you want: inspect the boss preview and live character requirement.
When to stop or switch
Stop when the weekly claim cap is reached or the planned Forte material need is met; reserve future claims for the next character bottleneck.
