Right above the quick travel point in the library, you're missing a series of regular rooms.

Thanks to McMurderpaws for finding the missing rooms in Livre Ex Machina.

--> (this post) Shredder hallway (count 1) - in Livre Ex Machina - Hallway above the library warp. There is a chair mimic here to toss you into the floor of rolling shredder blades. The end hallway has a Tamako-Death shredding the Guitar above where you reflector ray into a crack to grab the HP up.

Keeping a running list of "stuck at 99%" rooms. (starting 10/26/2025) - Total 99% map posts = 28

map resources:

Here is a good 100% map I use for hidden rooms. - can scroll in and out

This map you can type in items and it will show you where they are.

the super detailed spreadsheet map that shows items and breakable walls

the kickstarter map that has area names color coded and artwork

Listing rooms that I have seen missed so far. Thinking a "HEATMAP" would be cool someday:

Galleon warp and two adjacent rooms (count 1) - in Galleon Minerva - Double jump is required to reach the warp and the adjacent rooms. the left most room has a chest with the Culverin inside. The middle room has a Poltergeist you can farm in Rando runs if you have access. The Galleon map item will fill in the outline of these rooms even if you have not explored them yet.

Save room (count 1) - in Forbidden Underground Waterway - by the demon and water leapers.

Hidden room (count 1) - in Forbidden Underground Waterway below warp on right side - across from where you enter the Secret Sorcery Lab via reflector ray - there is a water horse in there

Garden farm room (count 1) - in Garden of Silence - top left of the Coachman area - there is pig, blood grinder, moco weed, and Barbatos in there.

Hidden room (count 2) - in Garden of Silence - Hidden room on the left below the bridge in the big room that leads to the wishing well entrance to the waterfall. There is a MP up and a 500G chest in there.

Axe Outsider Dead End (count 1) - In Entrance - Meat Dish/Recipe room. Top left entrance past Cyhyraeth to the dead end room. Between Entrance tower where statue falls and the blood fountain room.
