Slumbering Sanctuary

The Slumbering Sanctuary is a fourth level biome.

This old sanctuary quietly slumbers, lit by the glow of the strange, sap-like substance oozing from its walls. Its halls are eerily quiet, and countless statues litter the grounds. There is no way out- that is, without awakening the sanctuary.

Nothing likes to be awakened from their slumber, and these halls are no exception. The pulsing hues of the Sanctuary warm from blue to orange, and statues come alive when approached. Proceed with caution, or be slain for your trespass.

Access and exit
The Slumbering Sanctuary can initially only be accessed from the Insufferable Crypt, coming from the Ancient Sewers with the Ram rune. 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
A Caster elite with the Spider rune can be found here. It disappears after being defeated once.

Scrolls
The Slumbering Sanctuary contains 4 scrolls: 2 Power Scrolls (with a third located in a guaranteed Cursed Chest) and 1 Dual-stat scroll. When 3 Boss Stem Cells are active, this biome has 2 guaranteed Scroll Fragments, and when 4/5 Boss Stem Cells are active, this biome has 3 guaranteed Scroll Fragments. Typically, most of these scrolls are only accessible after 'awakening' the Sanctuary.

Secret areas

 * The blueprint for the Masochist mutation can be found in a secret area located in the wall in a narrow vertical passage with spikes at the bottom.
 * The blueprint for the Emergency Door can be found in a secret room where the player must reach the end without breaking any doors. This room does not always spawn, so it may require multiple runs to obtain.

Enemies
The blueprint for the Wings of the Crow and Pyrotechnics can be looted from Golems and Casters, respectively.
