For the Mod, see Sanctuary (Mod).

The Sanctuary is a Relay enclave where Cephalon Simaris currently resides. The room houses a variety of functions related to the lore of WARFRAME, mainly simulations and a mechanic known as Synthesis. Inside the Sanctuary, players can interact with Simaris, which is crucial for completing The New Strange Quest, as well as keeping track of the Synthesis progress, and purchasing offerings from Simaris.

As Cephalon Simaris refers it, the Sanctuary is a data oasis. Through Synthesis, the Sanctuary will uncover in-depth lore behind the WARFRAME universe, information that surpass the capacity of the personal Codex.

Synthesis is a community-driven research that will uncover knowledge of the WARFRAME universe, similar to the Codex. Once a Synthesis research has been completed, the Tenno will be rewarded with detailed lore relevant to the WARFRAME universe.

Sanctuary Onslaught[]

Main article: Sanctuary Onslaught

The Sanctuary Onslaught is an endless game mode introduced in Update 22.18 (2018-04-20). It is similar to Survival, though players are limited to one big room from a random tileset and opposing faction which is also randomized from round to round.

Players must complete The New Strange to access this game mode. To begin, players must talk to Cephalon Simaris at his Sanctuary in any Relay or select "Sanctuary Onslaught" in the Syndicate World State Window tab.



The Simulacrum is an artificial arena similar to the ones in Mastery Rank tests, that allows players to create multiple Mimeographs of enemies that the player had completed their Codex research on. Currently only the Mimeographs of normal enemies except Bosses and most Characters can be created.

The entrance of the Simulacrum is located on the left of the Sanctuary's entrance. Players must acquire a Simulacrum Access Key with ReputationBlackx64.png 50,000 to gain access to the arena.

There are two Simulacrums to enter:

  • The Citadel Simulacrum is the default Simulacrum with a wide open space featuring many tall pillars. The empty pits and lack of barriers make it possible to fall out of bounds.
  • The Ballroom Simulacrum is a reward from Operation: Scarlet Spear, Operation: Orphix Venom, and as a treat from Nights of Naberus. It is a much more enclosed space with several ramps and walkways, and invisible walls make it hard to fall out of bounds. It also features large statues of BaruukIcon272.png Baruuk and GaraIcon272.png Gara standing side-by-side.

The maximum capacity of the number of Mimeographs that can be generated is set at 20. Enemy level can be set by the player, up to 5x their Mastery Rank plus 30. Although one can only generate 20 Mimeographs at one time, enemies with spawning capabilities such as Brood Mothers or Drahk Masters can create subsequent Mimeographs while engaged.

An overview of The Citadel Simulacrum as of Update 18.0 (2015-12-03)

Behind the Simulacrum where the Arsenal can be accessed

Dying in the Simulacrum, notice that there is no option to revive or abort

The location is in an open space area with white walls and pillars, similar to the ones in Mastery Rank tests. One of the rectangular pillars is a spawn stage where the player can interact with the console on top of it to create Mimeographs. There are also various Pickups dispensers including Energy Orb, Health Orb and Ammo on top of the stage which regenerates rapidly when consumed.

Once the Mimeographs are generated upon player request, they will begin engaging the player, though some enemies with limited engagement range will remain idle until the player jumps off the stage. Falling off the Simulacrum area will lead to an instant respawn to the last valid location. Since there is no way to "complete" the session, the player must leave the session by accessing the Main Menu via Esc . Hence, any progress such as Affinity(enemies do not give Affinity here upon defeat) and Standing gain will not remain after the simulation. Various components and items will drop similar to the Orokin Void but, with the exception of Credits, will not be retained after exiting the Simulacrum. 

If the player dies, they will simply respawn at the normal spawn point and will not be given the choice of using revives or aborting the mission. As of Update 21, the Simulacrum is capable of multiplayer of up to 4 players in one instance. 

Gear items will be limited until the player goes back to the arsenal, where they will be refilled to the player's current amount. Specters will always spawn at level 1, regardless of the level of enemies on the field or if there are not. 

Mastery Rank Test Trials[]

CB MasteryHall.png

At the right side of the enclave is a corridor that houses multiple entrances of Mastery Rank test trials.You must have all types of weapons equipped to access them. Upon entering an entrance, the player will be transferred to a Mastery Rank test session of the specified Mastery Rank. Players can access any tests already completed, as well as the test for the next higher Mastery Rank.

This system will not affect the player's progress, allowing players to prepare for tests of their prospective Mastery level without penalties.

Conclave Maps[]

There are currently 2 maps for Conclave from this tileset.


  • Currently, players are able to scan mimeographs that spawn within the Simulacrum, but daily standing actually does not increase after exiting the Simulacrum.
    • Scans taken within the Simulacrum don't affect the scan count in the Codex.
  • Some enemies cannot be spawned as mimeographs, such as most bosses and Archwing enemies.
  • If a player remains idle for an extended period of time, energy and health orbs will become manual pickups that can only be collected with the context action key (default X ); Moving away will reset the idle period.


  • Juggernauts can spawn enemies that are hundreds of levels higher than the level set by the player, and above their own levels.
  • Juggernaut Behemoths will always spawn at level 500
  • Currently, while it is possible to generate Lynx mimeographs, it is not possible to generate Mimeographs of Sprag or Ven'kra Tel.
    • Lynx will always spawn at level 1.
  • Non-sniper weapons that utilize sniper ammo (e.g. the OgrisNew.png Ogris) start with 72 maximum ammo, regardless of the weapons normal maximum ammo. Affected weapons will be unable to restore ammo until their reserves have fallen below their normal maximum ammo.
  • Equipping or changing an Aura mod on a warframe will not apply the associated buff until the player is killed by an enemy and respawns.
  • If, as Limbo, a player enters the rift with the dash, then enters the arsenal and changes warframes, they will be unable to leave the rift until they switch back to Limbo, die or leave the Simulacrum. (Falling off the map, doesn't change this either.)
  • After the Simulacrum was open to multiple players, the option to pause the session was removed, even when solo. This is the same with the now open Captura mode.
  • Switching the Holster Style of a melee weapon causes Finisher attacks to always use Katana.png Nikana animations, no matter what melee weapon the player is using.
  • Switching an item, an equipment, or go to an upgrade window will give a much higher damage multiplier to your melee weapon. Glitch is removed when interacting with the spawner.
