Clean The Library Upgrade Priority Tier List

Clean The Library upgrade priority comes down to one question: what removes the most repeated work from your next clear? The best early upgrades cut book trips and pile chaos first, then improve movement, shelf finishing, route help, and late-run mistake cleanup once the library starts spreading you across both floors.

Upgrade Tier Rankings In Clean The Library

S Tier

Rank Name Reason
S1 Golden Diamond
Featured Golden Diamond is the cleanest S tier upgrade because +3 carry removes repeated delivery trips from the start of serious progression. It helps solo clears, co-op couriers, and casual runs before advanced routing matters. Large carry gamepasses are the only reason it feels less urgent.
S2 Sort
Featured Sort belongs in S tier once mixed piles become the main time sink. It turns messy floor piles into usable delivery groups and prevents wasted shelf trips. It is the first magic upgrade that really changes how quickly the whole cleanup pipeline moves.
S3 Azure Star
Featured Azure Star stays in S tier because its extra +2 carry stacks with Golden Diamond and keeps reducing trip count for the rest of the run. It sits slightly below Golden Diamond because the single boost is smaller, but together they make bulk cleanup much less punishing.

A Tier

Rank Name Reason
A1 Assemble Assemble fits A tier because gathering scattered books into a cleaner pile saves pickup time and gives Sort better material to work with. It is at its best in messy rooms and co-op dumps. It stays below Sort because gathered books still need sorting and routing before shelves fill.
A2 Emerald Club Emerald Club lands in A tier because sprint shortens long routes across the two-floor library and matters more once second-floor sections open. It is excellent for timed badges. It is not the first priority for most runs because low carry still forces too many trips.
A3 Auto-Shelving Auto-Shelving is A tier because final shelf placement repeats heavily after books reach the correct area. It saves late-run manual actions and pairs well with Sort. As an early priority it is weaker, because carry, gathering, and route knowledge still have to come first.

B Tier

Rank Name Reason
B1 Crimson Octagon Crimson Octagon sits in B tier because jump height helps routes, elevated access, and shortcut comfort without reducing sorting or carrying by itself. It matters more when a jump route leads to another key. For normal cleanup speed, carry and Sort come first.
B2 Shelf Guide Shelf Guide is B tier because destination help matters while shelf sections and color groups are still new. It prevents wrong turns, but repeated runs reduce its impact as map memory improves. Carry and sorting tools stay ahead because they remove work instead of only guiding movement.
B3 Insight Insight stays in B tier because finding misplaced books prevents late cleanup stalls, especially in co-op where teammates can create wrong placements. It is still a support upgrade: careful sorting and good carry priorities stop many mistakes before Insight has to fix them.

How This Upgrade Tier List Is Ranked

The order favors upgrades that change every run immediately: early impact, repeated time saved, free-player value, solo clear impact, co-op role impact, and speed badge value. Carry upgrades and Sort sit highest because they reduce trips and make every pile easier to process. Movement and direction tools come after the first carry gains unless your current route is losing more time to long aisles than to low capacity.

Clean The Library Tier List Notes

A
A tier upgrades are the next priorities. They speed up travel, gathering, or shelf completion, but they need better routing or later-game setup than S tier picks.
B
B tier upgrades solve narrower problems such as destination confusion or misplaced books. They help most after carry and sorting are already under control.
C
C tier upgrades wait until carry, sorting, and movement are covered in a normal clear.
D
D tier upgrades are skips unless they start reducing book trips, pile sorting, shelf placement, route time, or late-run mistakes.
S
S tier upgrades come first in most serious runs because they reduce trip count or pile chaos as soon as they come online.

Why Carry And Sort Come First

Golden Diamond, Azure Star, and Sort rank high because they attack the two chores players repeat the most: walking books to shelves and making mixed piles readable. More carry means fewer delivery loops across the first and second floors. Sort turns scattered colors into a cleaner pipeline before a player wastes time carrying the wrong book to the wrong shelf.

Movement After The First Carry Boost

Emerald Club and Crimson Octagon become better after the player has enough carry to make long routes worthwhile. Sprint shortens second-floor aisle travel and timed badge attempts, while jump helps with elevated routes and key access. They are not bad first picks, but a fast player with low carry still burns time repeating trips.

When Support Abilities Matter

Shelf Guide and Insight help when the library becomes visually messy or a player is still learning shelf sections. They do not beat Sort or carry upgrades because they answer mistakes after the pile has already formed. Auto-Shelving is different: it becomes an A tier upgrade because final placement repeats heavily once books reach the correct shelves.

Clean The Library Upgrade Priority Tier List FAQ

What upgrade should I prioritize first in Clean The Library?

Golden Diamond is the best first priority for most players because +3 carry cuts repeated trips immediately. Sort is the best first magic priority because mixed piles slow every shelf route.

Are keys or abilities better early?

Keys are better early if you can reach Golden Diamond or Azure Star quickly. Abilities catch up once Sort unlocks, because sorting mixed piles saves time even before a player fully knows the map.

Why is Emerald Club not S tier?

Emerald Club sprint is excellent for speed attempts, but sprinting with low carry still creates too many trips. It becomes stronger after Golden Diamond or Azure Star reduces the number of delivery loops.

Should co-op teams follow the same priority?

Co-op still starts best with carry and Sort, but the team can split jobs sooner: one player hunts keys, one player builds sorted piles, and another uses Shelf Guide or Insight to catch mistakes.
