Ability index

Clean The Library Abilities

Competitor research shows ability pages are a real content gap. This index covers ability roles and upgrade judgment without inventing exact costs, cooldowns, or unlock steps.

Deep comparison result

Entity pages were missing

Ranking competitors split abilities into standalone pages. This site only had a tier-list summary before this pass.

Source boundary

Roles, not fake numbers

Ability names and demand are supported by community surfaces; exact mechanics still need direct gameplay verification.

Best use

Match the run bottleneck

Pick collection, sorting, direction, placement, or audit help based on what is slowing the clear.

Ability pages

Compare each ability by route role

These pages are designed for searchers who need a concrete upgrade decision, not a copied wiki table.

Stack cleanup

Sort

Sort is the safest early upgrade signal because it improves the core loop: turning mixed piles into books that can actually be shelved.

Collection

Assemble

Assemble is a high-value collection helper when loose books are scattered and walking time becomes the main clear-time bottleneck.

Error audit

Insight

Insight matters most near the end of a run, when one misplaced book or wrong volume order can make a shelf look finished but fail to complete.

Direction finding

Shelf Guide

Shelf Guide is useful for players who lose time translating a book theme into the correct floor and shelf section.

Placement assistance

Auto-Shelving

Auto-Shelving sounds strong, but without verified activation details it should be treated as a convenience candidate, not an automatic first pick.
