The quick answer
Mountain’s Might requires five page chests in the Palace of Annals complex. Collect the full set, Comprehend it, and use its Endurance support through Nameless Spear’s Qiankun’s Lock.

Collect the five distinct chests
Two chests are in the Hall of Seasons building and three are along the underground Palace of Annals campaign route. Each contributes two pages, so all five complete the ten-page set.
| Chest area | Where to inspect |
|---|---|
| Hall of Seasons upper floor | Third-floor balcony |
| Hall of Seasons concealed floor | Hidden second floor |
| Underground archives | Right side of the archives room on the second level below the palace |
| Deeper underground, right branch | End of the path reached by the right stairs on the third level below |
| Deeper underground, left branch | End of the corresponding left-stair path |
Treat the two deeper branches as separate checks. Following only the campaign’s onward marker can leave a side-path chest behind. Record the page total after each pickup so you know whether the chest actually contributed to this art.
Resolve 80 percent comprehension
An incomplete total means the set is unfinished; defeating Lucky Seventeen is not a substitute for the missing chest. Recheck the above-ground floors and both deeper branches before repeating the boss.
Once the full set is present, use Comprehend in Inner Ways. Later Notes advance the learned passive; they are a different item from these acquisition pages.
Connect it to Qiankun’s Lock
Mountain’s Might supports Nameless Spear’s Endurance economy through Qiankun’s Lock and its associated effect. It is not a generic benefit for every spear art. Heavenquaker and Stormbreaker have different named skills.
Use the spear action before the Endurance-intensive portion of your intended sequence. Then inspect what your current tier changes: duration, recovery and later marked-target support are not all base features.
Make the saving useful
An editorial comparison is to run the same short spear-to-sword sequence with and without the passive while watching Endurance. Keep enough resource for defence in both attempts. The practical question is whether the support lets you complete useful attacks while retaining an escape, not whether you can empty the bar with a longer combo.
If you do not use Qiankun’s Lock, fix that compatibility issue before investing. If you do use it but still run dry, inspect the order and timing of charged actions. More recovery cannot make an unsafe attack window last longer.
Upgrade for the next concrete change
Read the next tier’s feature and compare it with your actual limitation. A player who needs a longer support window has a different reason to invest from one seeking later marked-target recovery. Keep the decision tied to the Nameless pair you play.
