Junctions are solo missions aboard Solar Rail network nodes that allow players to progress through the Star Chart.


Junctions consist of a small, circular room, with a specter kneeling in the center. Each Junction is accompanied by a series of specific tasks. Completing these tasks is required to challenge a Junction's specter for control of the connected Solar Rail, which unlocks the next celestial body.

In addition to star chart progression, completing a Junction grants 1,000 Mastery and several miscellaneous rewards (typically weapon blueprints and/or quests). Junction rewards can only be claimed once.

  • Junctions can be used as shortcuts between celestial bodies when navigating the star chart.
  • Players may enter the junction even if they have not fulfilled the tasks. They will, however, be barred from fighting the specter of the Junction, thus unable to progress through the rail.
    • The list of tasks and rewards will be shown in the rail, in front of the area the player is barred from entering into. This is the same list as the one shown on the star chart.
    • Exiting a Junction will not be considered a mission failure.
    • Specters can be scanned even if the player is prevented from attacking them.
  • Certain paths between celestial destinations do not have Junctions, and can be traversed as soon as the nodes at either end are unlocked. They are:
    • All the paths leading to the Void.
    • The path leading from Earth to Lua.
  • Specters reward approximately 2,000 affinity when killed.
  • The Neptune Junction's requirements will count the use of any exalted melee weapon as a normal melee weapon.
    • Also, it will not count Archwing primary weapons against the requirement. You can safely take an Archwing primary into a submersible mission while still counting as "melee only".
  • To complete the "Open 3 caches during any Sabotage mission on Uranus" requirement of the Neptune Junction you don't have to find and open all the three caches of a single mission but you have to open 3 caches "in total". So, even opening only one cache each in three Uranus Sabotage missions should work
  • One of the four tasks needed to unlock the neptune junction cannot be completed with Hildryn, "Complete any 5 missions on Uranus with ONLY your melee weapon equipped" because her Balefire Charger weapon cannot be unequipped. (However, you can do it with Mesa, even if you have the regulators.)


  • Using crowd control abilities that stun or freeze enemies (e.g. VoltIcon272 Volt's Discharge130xDark Discharge and HarrowIcon272 Harrow's Condemn130xDark Condemn) will leave Specters completely vulnerable to the player's attacks, making Junctions relatively trivial.
  • As the level of the Specters increases so do their firepower, potentially threatening and, in some extreme cases, killing the player in a matter of seconds. It is recommended to bring a frame with either the ability to protect themselves from damage (e.g. VoltIcon272 Volt's ElectricShield130xDark Electric Shield or ValkyrIcon272 Valkyr's Hysteria130xDark Hysteria), the ability to heal themselves (e.g. TrinityIcon272 Trinity's Blessing130xDark Blessing), or that can decently tank damage (e.g. RhinoIcon272 Rhino or InarosIcon272 Inaros). If you have an Inaros, it is very easy to finish this while closing in on the Specter and use his Devour ability, thus taking little to no damage.
    • Alternatively, players can bring frames that are able to turn themselves invisible, such as LokiIcon272 Loki or IvaraIcon272 Ivara.
    • MagIcon272 Mag's Magnetize130xDark Magnetize can also trivialize the Specters; the ability roots them in place, preventing them from using melee attacks unless the player allows, and it also redirects all gunfire towards them, including their own. In effect, this causes Mag to be entirely safe for the duration, allowing her to free-fire on the Specter while they deal self-damage.
  • Using FrostIcon272 Frost's SnowGlobe130xDark Snow Globe ability knocks Specters back and deals large amounts of damage.  Many (but not all) of the specters will also remain outside the globe, preventing them from dealing any damage to Frost until the globe has been broken (which is typically more than enough time to kill the specter from within the globe).
    • Additionally, his Freeze130xDark Freeze ability can be used repeatedly to prevent the Specter from moving or attacking allowing you to constantly melee them.
  • AshIcon272 Ash's BladeStorm130xDark Blade Storm ability alone can usually kill specters in one hit.  Specters are also vulnerable to Ash's Mod TT 20pxFatal Teleport augment, causing significant damage (often killing the specter outright) and preventing Ash from receiving damage for the duration of the finisher animation.  Since Teleport can be cast back-to-back for chained finishers, this can be used to quickly kill any of the specters with virtually no risk.
  • Specters are vulnerable to HydroidIcon272 Hydroid's Undertow130xDark Undertow.
  • Specters can be Enthrall130xDark Enthralled by RevenantIcon272 Revenant.


  • Each specter is based on the Warframe whose components drop from the next location's boss, with the exception of VoltIcon272 Volt on Mercury, FrostIcon272 Frost on Mars, TrinityIcon272 Trinity on Ceres, and ExcaliburIcon272 Excalibur on Pluto.
    • Volt is the specter of the Mercury Junction because Captain Vor doesn't drop any Warframe Parts blueprints.
    • The latter three were the result of a reshuffling of drop locations for each frame introduced in Hotfix 22.8.3.
  • Players retained any star chart progress made prior to Update: Specters of the Rail. However, Junctions themselves still needed to be completed to gain their rewards. Furthermore, Junction tasks only counted progress made after the update, with the exception of completed quests.
  • Junctions were inspired by Hyper Light Drifter.[1]
  • The Junction tile set was used as a Railjack prototype.[2]


  • The large window in the Junctions is not solid, allowing players to knock the Specter out into space with the appropriate abilities and weapons.
  • The Sedna Junction may not allow the player to enter even when all four requirements have been met or the junction has already been completed.
  • If a Junction is already completed and the player returns to scan the Specter for a codex entry, the Specter must be scanned and killed, then the player must return a second time and repeat this process for the codex entry to show up.
    • This bug can be bypassed by exiting the junction from the Esc  menu.

  • Fixed an issue with Client Junction Tasks not tracking. This means any Clients trying to complete tasks wouldn't see progress.

Hotfix: Specters of the Rail 7

  • Completing the Vor's Prize quest missions will now mark the nodes they're on as completed, so that you don't have to backtrack and complete the nodes leading up to the Junction a second time before you can enter it. Anyone who is mid-quest after this Hotifx deploys will still have to backtrack.
  • We now allow progress towards Junction tasks during the tutorial, and with this we also fixed Junction tasks not working during Quests.
  • You can now revisit Junctions, and see their new and improved diegetic menu!

  • Rebalanced the Rhino Specter in the Junction to be more manageable for new players.
  • Updated the Earth (to Venus) challenge text to better indicate the challenge requirement to "Apply 4 MODS to a single Warframe or Weapon", not just overall.
