Slumbering Sanctuary

Access and exit
The Slumbering Sanctuary can initially only be accessed from the Insufferable Crypt, coming from the Ancient Sewers with the. After defeating the Elite Caster and obtaining the Spider rune (see below), a passage from the Black Bridge also becomes available.

There are two normal exits out of the Slumbering Sanctuary, leading to the Clock Tower and to the Forgotten Sepulcher. Another exit, located behind a 2 BSC door, becomes available after beating the Giant once and leads to the Cavern.

Awakening the Sanctuary
When entering the level, the Sanctuary is in an 'inert' state, with a considerable number of enemies frozen as grey statues in the background. At the edges of the level, orange doors will prevent further progress. It should be noted that the only teleporters in this portion of the level are at the entrance and behind the switch.

Once the Ancient Temple Switch is activated, the level's coloration will change to orange and the music will change. The orange doors will now be open, and the statues will change into living enemies when approached. These enemies can be elites, and will not be rooted in place; as such, the statues should be approached with caution.

Spider Rune
An Elite Caster with the can be found here. It disappears after being defeated once.

Scrolls
The Slumbering Sanctuary contains 4 scrolls: 2 Scrolls of Power (with a third located in a guaranteed cursed chest) and 1 Dual Scroll, which cannot spawn in areas requiring the use of runes to access. On (3+ BSC) there is a bonus Scroll of Power. When 3 Boss Stem Cells are active, this biome has 3 guaranteed Scroll Fragments, and when 4/5 Boss Stem Cells are active, this biome has 4 guaranteed Scroll Fragments. Typically, most of these scrolls are only accessible after 'awakening' the Sanctuary.

Alchemist grimoires
In a lab, the alchemist notes it's believed the Malaise is flowing into the sewer network and causing the malaise. He also wonders if the problem can be the solution:


 * "Some say the sap that runs through the walls is flowing into the sewer network and causing the Malaise. But perhaps the problem can also be the solution?"

The Alchemist discloses, in yet another lab, the Time Keeper can't contain the malaise forever with her time loops, noting she's getting exhausted from it:


 * "Time is running out... literally. With all due respect, she can't contain the Malaise 'forever'."

In another lab, the alchemist states he has to collect as much sap as possible and find a solution:


 * "All the sap flowing through these stones... I have to collect as much as possible and find a solution."

Additionally, when the beheaded makes a remark on the liquid in the walls:


 * "I've passed by it dozens of times but I've never wondered what the viscous liquid in the walls was."
 * "It's pretty, but it sort of stinks."
 * "It's pretty, but it sort of stinks."

Other rooms
Randomly found, a lore room containing many doors can appear with a sign, which reads:


 * "Are you worthy?"

If the player destroys any door in the room, the sign will read:


 * "You are not worthy."

Or the player doesn't destroy any doors, the sign will read:


 * "You proved your worth."

And will drop the blueprint.
