Plexus
Polarities

The Plexus allows you to use your Railjack mod selection with any Railjack you crew upon.

Plexus Mods can be found in Railjack missions. Integrated Mods apply to you on any Railjack! Aura Mods impact the whole squad! Battle Mods determine which Railjack Abilities you can use on a Railjack. Tactical Mods determine which Railjack Abilities you can use in the Tactical Menu.

—Upon first interacting with the Plexus

The Plexus is a modular item that modifies the player's personal (and NPC Crew) performance in Railjack. It is the Warframe equivalent of modding for Railjack.

Mechanics

The Plexus is acquired after completion of The Archwing and comes with a pre-installed Orokin Reactor as well as , , and polarities. It can be ranked up during Railjack missions up to Rank 30, providing 200 Mastery Rank experience per rank up to 6,000 in total, and can be given Forma and Aura Forma. The Plexus can be configured in the front of the Orbiter between the Navigation and Syndicate segments, or from Dry Docks in Relays and Clan Dojos.

Railjack-exclusive mods are divided into three types: Integrated, Battle, Tactical. There are 9 Integrated slots, eight normal and one aura, and have a modding capacity. Battle and Tactical mods do not use capacity, but are further divided into Defensive, Offensive, and Super types, of which players can only slot in one of each.

The Plexus is personal to the user; this allows each individual in a squad to have different configurations and abilities that will only apply to themselves. For example,  Hyperstrike only affects the user's own turret damage and not the rest of the squad's.

When playing with NPC crew members, they will all equip an exact copy of the host's Plexus loadout, including the Plexus Aura mod. However, crew members will not use Battle or Tactical abilities.

Integrated

Integrated mods provide passive bonuses to the player/crew member. Aura mods provide bonuses to the entire team and/or Railjack.

Battle

Battle mods provide powerful abilities that are used similarly to Warframe abilities (default 1  for Defensive, default 2  for Offensive, and default 3  for Super). They consume the Warframe's own energy to use (shields in  Hildryn's case and cooldowns in  Lavos's case). Like Warframes, the Railjack possesses an Ability Strength, Ability Duration, and Ability Range stat to enhance Battle abilities which can be increased with the Railjack's Reactor, but are unaffected by Warframe ability enhancement mods.

Defensive Abilities cost 50 energy, Offensive cost 100, and Super cost 200 (with  Countermeasures and  Phoenix Blaze being exceptions to the rule).  Hildryn's shield costs are 10 times the default.  Lavos's cooldowns are 10 seconds each, and cannot be reduced in any way. An ability's energy cost will double after initial use, which will return to normal values after 5 seconds. Energy cost is affected by Tactical Intrinsic Rank 6 and  Onslaught Matrix, but not Warframe Ability Efficiency mods such as  Streamline or  Blind Rage. Energy generation such as  Energy Siphon, Squad Energy Restores, and Energy Orbs will still function while in the pilot/gunner seat.

As ability cost is tied to Warframe energy, Warframes with high base energy and modded with  Flow and/or  Preparation will ensure a good amount of starting energy to cast Battle abilities. Note that Preparation does not refresh when transitioning between missions.

Tactical

Tactical mods provide special abilities that are used from the Tactical Menu. They do not consume resources to use, instead having cooldowns.

Patch History

Hotfix 31.5.5 (2022-05-03)

• Fixed the Plexus opened from the Orbiter not maintaining the mod equipped in the 8th slot after closing and re-opening screen.

Hotfix 30.2.1 (2021-05-13)

• Fixed a script error when viewing the Plexus.

Hotfix 29.10.7 (2021-03-26)

• Fixed inability to Mod your Plexus until you own a Railjack.
  • The intended flow here is when you complete The Archwing Quest and are awarded your Plexus, you can Mod it and join others on their Railjack missions to help out until you get yourself a Railjack. You’ll now be able to Mod it, but won't be able to see Railjack stats unless you actually own one, as the Plexus doesn’t have any Railjack data to pull from yet.
• Fixed attempting to search for a Mod in the Plexus by using the Left Stick on a controller not activating the search bar.

Update 29.10 (2021-03-19)

• Introduced.
