Forgotten Sepulcher

"Once reserved for high-ranking dignitaries, the sepulcher became a tortuous labyrinth, its reaches fading into obscurity and myth..."

The Forgotten Sepulcher is a fifth level biome.

If someone was of note for the history books, they were buried here. A strange ritual was to use the bones as adornment for the sepulcher as some sort of decoration. However, the Malaise resulted in the former dignitaries abandoning it altogether, leaving it to the darkness. This darkness gathered like a haze, gnawing and chewing on any source of light found here, as well as making its ways into the bodies of the dead. It took over them, and made them dance a deadly, murderous dance. Now, little light other than that from the sparse lanterns lurks here. In the minds of the survivors, this labyrinth no longer exists.

Access and exit
The Teleportation rune is required to access this Biome from the Stilt Village. A secondary path coming from the Slumbering Sanctuary is also available. Finally, a third entrance leads to the Sepulcher from the Graveyard.

Two exits lead out of the Sepulcher: the natural route takes the Beheaded to Clock Room, at the top of the Clock Tower where the Time Keeper awaits. Another path becomes accessible after beating the Giant once and when playing with 2+ BSC active: a door next to the Clock Room exit leads to the Guardian's Haven.

The Darkness
The Darkness creeps closer and starts to eat away at the players health after not having been close to a light source for 12 seconds. The damage starts off at 0.1 per tick and gradually increases to 6 damage per tick, with damage being applied every 0.3 second. Killing a mob reduces the darkness by 11%.

Note that the Darkness does not trigger death by curse. On the other hand, the mutation Disengagement does not protect from Darkness damage.

Scrolls
The Forgotten Sepulcher contains 5 Power Scroll and no Dual-stat scrolls. These can spawn in areas requiring the Teleportation rune, but not the Spider rune.

Secret areas
The blueprint for the Hayabusa Boots is found in a secret area behind a locked door, close to the Clock Room exit. To reach it, the player must first defeat a couple of Elite Dark Trackers. These two Elites will always be present, and the reward will be replaced by a gem or item on subsequent visits.

Blueprints from enemies
The blueprints for the Spiked Shield and Death Orb are exclusively found in this biome, and are looted from Cleavers.

Enemies
In the Forgotten Sepulcher, you will find plenty of Dark Trackers, along with Cleavers. These two enemies could be considered iconic of the Sepulcher, particularly in the case of Cleavers which are unique to this biome. In addition, Shockers, Kamikazes, Inquisitors and Lacerators can be found, as well as Knife Throwers, Shieldbearers and Failed Experiments on higher difficulties.

In the table below, you will find which enemies are present in the Forgotten Sepulcher depending on difficulty level. For each enemy, any common, uncommon, rare or legendary blueprints they carry are indicated. When applicable, the minimum difficulty level for blueprint acquisition is specified in brackets.
