Efficient players upgrade in stages.
Early upgrades are for testing the holder. Raise the Arc enough that it does not distort the test, then run content. If the holder cannot use the 10-second window, stop before spending high-tier materials.
This stage is about information, not final power.
Continue investing when the Arc belongs to a character you use often and the team plan is stable. At this point, the material cost supports a real build rather than a temporary experiment.
This is where many players should decide whether Fluff is a long-term Arc or a bridge.
Level 80 gives 512 ATK and 22% CRIT Rate. Maxing is best when the Arc is on a core Solid DPS and you have compared alternatives. If a better Arc is likely soon, waiting may be smarter.
Max level should feel like finishing a proven build, not gambling on a build you have not tested.
Every material spent here is not spent elsewhere.
The total Beetle Coin cost is large enough to affect other upgrades. If your account is still raising characters, gear, and multiple Arcs, plan the order carefully.
A strong Arc is valuable, but a half-built team can still underperform if all resources go into one slot.
Cold Dessert items appear across multiple upgrade stages. Track which tier is blocking your next ascension so you do not farm inefficiently or overfarm the wrong item.
A simple checklist can save time, especially when planning the push from 60 to 80.
Suspended, Yearning, and Transcendent Delusions appear in different upgrade ranges. Treat the higher-tier materials as commitment resources rather than casual test materials.
Use them when the holder and team are already confirmed.
The final decision depends on account value, not completionism.
Upgrade to 80 when Fluff of Fearlessness belongs to your main Solid DPS, the holder uses the buff window well, and no stronger Arc is available. The final stat line is meaningful for sustained account use.
This is the cleanest case for full investment.
Wait if the holder is temporary, another Arc may replace it soon, or your account has more urgent upgrades. A partially upgraded Fluff can still be useful while you gather information.
Waiting is not wasted time when it prevents resource regret.
These examples show how different accounts should treat the same cost table.
A low-resource account should not rush level 80. Raise the Arc enough to test the holder and then pause. If the holder becomes part of the main team, continue. If the holder changes, the paused investment protects rare materials.
This is especially important when characters, gear, and other Arcs are also competing for resources.
If Fluff of Fearlessness belongs to the main Solid DPS and performs well in daily play, level 80 becomes more reasonable. The final stat line is meaningful, and the material cost supports a build the player actually uses.
This is the cleanest case for full investment because the Arc is not sitting in inventory or serving as a temporary experiment.
If the player expects to pull a stronger signature Arc soon, material spending should be conservative. Fluff can act as a bridge, but bridge items do not always deserve maximum investment.
Use the Arc enough to keep the account functional, then reassess after the planned pull or banner decision.
Use these examples to decide whether to stop or keep investing.
Raise the Arc enough to avoid an unfairly weak test, then use it in real content. The testing route is best when you are unsure whether the holder will remain part of your main team.
If the holder fails the rotation test, stopping early protects high-tier materials.
If the Arc belongs to your main Solid damage dealer and the rotation works, pushing toward level 80 becomes more reasonable. The final 512 ATK and 22% CRIT Rate are meaningful when the Arc is used every day.
This is the cleanest case for full investment.
If you expect to pull a stronger signature Arc soon, treat Fluff as a bridge. Upgrade enough to keep the account functional, but avoid spending the final materials until your long-term plan is clear.
Bridge items are useful, but they do not always deserve maximum investment.
