Arbitrations are a special Alert variant hosted by the Arbiters of Hexis, featuring "elite" versions of endless missions with additional modifiers for greater difficulty. They were introduced in Update 23.10.


In order to access Arbitrations, players must have completed all nodes on the connected Star Chart, including Dark Sectors, Lua and the Kuva Fortress, as well as the lone nodes of the Orokin Derelict. The only two exceptions are the disconnected Assassination nodes of Mutalist Alad V and the Jordas Golem on Eris. Players can check on what nodes they need to complete by talking to the Arbitration representative in the Arbiters of Hexis' Relay enclave.

Note that this also entails completing the Ropalolyst node, which requires players to have completed the Chimera Prologue and all the story quests leading up to it.

Once players have Arbitrations unlocked, it will be displayed on the Operation window. There is only one Arbitration alert up at any given point on the Star Chart, changing nodes on an hourly basis. Arbitrations will only select nodes with endless missions (Survival, Interception, Defense, Excavation, Defection, or Infested Salvage), and the enemy level range will start at 60-80.


  • Once a player loses all their Health, they do not enter the Bleedout phase; they die instantly. Furthermore, they are not allowed to revive themselves.
    • Mod TT 20pxSacrifice does not work in Arbitrations, and neither will InarosIcon272 Inaros' Undying Passive.
    • Note that the absence of Bleedout also extends to the player's Companions. Kavats can prevent death by being equipped with Mod TT 20pxTek Assault, and Sentinels equipped with (Mod TT 20pxPrimed) Mod TT 20pxRegen or Mod TT 20pxReawaken will function as normal.
    • When a player dies, a Revive Tower will appear at their place of death with a waypoint, and Arbitration Shield Drones (see below) will begin to drop Resurgence Tokens on death.
      • Resurgence Tokens function identically to Index Points: Picking them up will give the stacking Resurgence Burden debuff, which lowers Warframe maximum health and shields and constantly drains energy.
      • 5 Resurgence Tokens are needed to revive a dead player, but they do not need to be carried by the same Warframe. Warframes carrying a cumulative total of 5 points must bring them to the Revive Tower at the same time.
      • If a Warframe carrying Resurgence Tokens dies, all the tokens they are carrying will be lost.
      • Resurgence Tokens are unaffected by Mod TT 20pxVacuum and Mod TT 20pxFetch.
      • Once all players are revived or the dead players leave the mission, excess Resurgence Tokens will disappear, removing the debuff.
  • Rewards are on a ABCC... rotation, as opposed to the AABC rotation used in normal missions. After the first two rotations, the Arbitration will continue on the C rotation endlessly.
  • Rotation lengths are twice as long as normal missions (e.g. Survival gives one reward every 10 minutes, Defense gives one reward every 10 waves, Interception gives one reward every 2 rounds, and so on). Additionally, the missions also sport modifiers unique to each;
    • Survival: Life Support Capsules are worth 75% of usual.
    • Interception: Enemy towers fill twice as fast.
    • Defense: The defense objective is a Hexis Operative NPC armed with AHAkbolto Telos Akbolto. Unlike Sortie Defense, the Operative follows a chosen player instead of roaming by themselves, and can't be given a weapon by a Tenno. Downtime between waves is reduced to 2 seconds. Like players, the Operative will not enter Bleedout, and their death will be an instant mission failure.
    • Excavation: Defense time is increased from 100 seconds to 180 seconds.
    • Defection: Rescue targets cannot be revived.
    • Infested Salvage: Consoles have half their normal health.
  • While quitting the mission will not yield any rewards, failing the mission keeps any rewards earned at the end of a rotation, but not any resources or credits enemies may drop.

Arbitration Shield DronesEdit

Arbitration Shield Drones will spawn among the enemy ranks. They function similarly to Shield Ospreys, but instead:

  • Grant complete Damage and Warframe Ability immunity to nearby enemies (except other Arbitration Drones). They are also immune to Warframe abilities themselves.
    • The ability immunity extends to LimboIcon272 Limbo's Rift Plane, in that they are unable to enter it and therefore cannot be killed by someone inside the Rift even while inside a Cataclysm130xDark Cataclysm. You can still switch to your Operator to damage the drones as it cannot enter the Rift Plane either. Enemies protected by the drones will not damage players inside the rift.
    • Builds focusing on area of effect damage might be difficult to employ as most enemy squads are being escorted by Arbitration drones. As the explosion of the drones provides a form of area damage and crowd control, focusing on single-target damage can be more viable to some.
    • Despite being weapons, the drones are also immune to all damage and effects from all Exalted weapons.
  • Explode on death, dealing 3000 Blast b Blast damage to all enemy units, including other Arbitration Drones, in an area of effect.
    • It's recommended that players deal with the drones as quickly as possible. Projectile launchers or weapons with large projectile hitboxes such as CrpShotgun Arca Plasmor are ideal for this task, as the drones are fairly small and move around quickly. Sniper rifles are also a good choice to pick out the drones from afar.
    • The death explosion can damage nearby Arbitration Shield Drones. Use this to your advantage.
    • As of Hotfix 23.10.7, Arbitration Shield Drones do not benefit from the Ancient Healer's damage reduction aura.


  • To encourage gameplay diversity, players are given a +300% Ability Strength bonus and a +300% Damage bonus to a random Warframe and Weapon for each alert. The affected Warframe and weapon change from one player to another: for example, one player could be given bonuses for playing with ExcaliburIcon272 Excalibur and/or a DESkana Skana while another player can be given bonuses for playing with MagIcon272 Mag and/or a Braton Braton.
    • The bonus can also be applied for Warframes and Weapons the player does not own.
    • Bonuses will also apply to any variants the Warframe or weapon may have (Prime, Syndicate, etc.).



Arbitration Alerts reward one unit of Vitus Essence for every rotation completed. Players can use their collected Vitus Essence to purchase unique items and mods from the Arbitration representative.

As mentioned above, additional end-of-rotation rewards are given out at half the rate as normal missions, A and B being the first and second rotations respectively then all subsequent rotations being C for the remainder of the mission (A-B-C-C-C-C-...etc).

  • Vitus Essence is also used to craft items, mainly Ephemeras.

  • The most common way to die suddenly is by enemy grenade. They are small and hard to see, but they do make a beeping noise. Be wary of them, as they can blast through even the tankiest frames.
  • Do not bring self-damage weapons, unless you really know how to use them. Even then, you probably shouldn't. If your weapon is modded to do significant damage to Arbitration enemies, any self-damage will probably one-shot you through whatever damage reduction you have. Fatal self-damage will not trigger death prevention effects, such as Mod TT 20pxQuick Thinking, Mod TT 20pxPhoenix Renewal, and NidusIcon272 Nidus' Undying passive.
  • The most useful non-Warframe specific mods for survival are Mod TT 20pxAdaptation and Mod TT 20pxQuick Thinking, and it is highly recommended to have at least one of them equipped.
    • Since Adaptation can only be obtained from Arbitrations, it is often prudent to trade for it, and sell the copies you will inevitably get as rewards to recoup the cost.
  • Despite the presence of Warframe-specific bonuses, they will rarely make them more viable than survivability-focused frames. Survival of yourself, your teammates, and the objective (depending on mission type) is key to success, so it is wise to use a frame with high effective health such as RhinoIcon272 Rhino, NezhaIcon272 Nezha, InarosIcon272 Inaros, or a frame with healing and damage reduction support such as TrinityIcon272 Trinity or OberonIcon272 Oberon. Killing the enemies is no harder than a sortie mission, so the large increase in Power Strength is welcome but ultimately unnecessary.
    • The bonus can open alternatives to builds however, as it will provide massive Power Strength that would otherwise require several Mod slots, capacity, and penalties from Corrupted Mods. A Trinity for instance can focus entirely on Duration and her own survivability, while the boon caps out her Blessing130xDark Blessing's scaling.
  • Specters can be used to aid you and your allies throughout these missions, making it ideal to bring them in situations where defending a key point is the objective (Defense, Interception, and Infested Salvage). It isn't advised to use specters that do not prioritize following the player (Ancient Healer specter, Charger specter, etc) in the other endless missions (Survival, Defection and Excavation), as movement is mostly key to success there. 
    • Trinity Warframe Specters are able to heal the defense target in defense missions, while also offering great energy regeneration, making it an ideal Warframe specter to bring to this mission type.
    • Ancient Healer specters can be used to reduce incoming damage greatly for you and your teammates, and Shield Ospreys can be used to grant extra shields and a greater shield regeneration rate.
    • Other specters that have no special abilities or traits, such as the Charger or Roller specter are not really recommended as their durability is very low and they tend to not follow the player. However they can serve as a distraction, drawing aggro away from both you and your teammates.


  • The randomly selected Ability Strength and Weapon Damage bonuses may not consistently apply to all Prime Warframes and Prime Weapons.


  • Arbitrations were originally known as "Elite Alerts" when they were pitched by the Development Team.

Patch HistoryEdit

  • Fixed not receiving rewards at End of Mission if you’re awaiting revival while extraction is triggered by the remaining squadmates.
  • Fixed losing Arbitration Warframe/weapon buff each time a player respawns.

Hotfix 24.8.1

  • In an effort to increase visibility, both the Arbitration Shield Drone beam and Resurgence Burden colors have been changed to a more orange hue! We've also cranked up the contrast and added a more recognizable pulsing FX.
  • Resurgence Burdens are no longer affected by Vacuum.
  • All Resurgence Burdens will now be removed if the player needing revival leaves/dies, and if you die while carrying Resurgence Burdens.

  • Fixed losing all Resurgence Burdens after a Host migration if a player was still in need of revival.

Update 24.8

Arbitrations ‘Iteration 1’ Changes

Our goal with this update is to maintain the challenge that Arbitrations promised, while also ensuring that if you or a teammate is knocked out, they still have a chance to jump back into the fight! Iteration 1 brings the discussed Revival mechanic and enemy scaling changes to mirror normal Endless mission modes. We will be watching how these changes play out as we plan to iterate further on the mode in the future, with our next review for Arbitrations focusing on reward pacing.


The rules of Arbitration death have shifted: players are still downed with no bleedout timer, but a Revive tower is now placed at the player’s spot of death. If any squadmate is awaiting Revival, the Arbitration Drones will begin dropping unique pickups known as a “Resurgence Burden”. These pickups function similar to Index points (otherwise known as “Financial Stress”), debuffing the players who carry them.

In order to revive a player, 5 of these Resurgence Burdens must be taken to their tower simultaneously. These 5 pickups can be delivered by one or multiple squadmates, but cannot be “dropped off” at the tower - it’s all or nothing!


You can now spend Vitus Essence in the Arbitrations Market to purchase Archgun Rivens (if you are below your Riven cap), as well as new cosmetics! The new cosmetic offerings include:

ILLUMINA JUDICIUM (name showing incorrectly in game. Will be hotfixed)

Let Arbitration begin.

A similar Emote style to the TennoCon 2019 Emote, the Illumina Judicium displays your true dedication to Arbitrations with a looping Vitus Illumina Glyph whilst doing an angsty Meditation pose.


Eyewear created by the Arbiters for those they deem worthy.

Also, enemies now have a chance to drop the elusive Aura Forma Blueprint! Craft Aura Forma to further customize your Warframe and fine-tune your Mod builds.

General Arbitrations Changes
  • Removed custom enemy level scaling from Defense, Survival, Interception, Excavation, Defection, and Infested Salvage modes in Arbitrations. Enemy scaling now mirrors normal Endless missions that increase as the missions progresses.
