Best Warframe for Arbitrations (2026)

Top frames, weapons, stat priorities and mods for Arbitrations

Last Updated on September 20, 2026

The short answer

Revenant is the safest pick because Mesmer Skin blocks the killing hit outright, and in Arbitrations one death ends your run. Trinity, Wisp, Chroma and Inaros are the other frames that survive level 60 to 80 with no bleedout. Bring a real gun: the shield drones ignore ability damage.

Researched September 19, 2026, current through Update 43.5. Picks need two independent sources; anything we could only confirm once is left out.

Frame	Why	Build focus
Revenant	Mesmer Skin charges block hits outright and stun the attacker, which matters most in a mode with no bleedout and no self-revive.	strength high
Trinity	Blessing heals the whole squad and adds damage reduction, and Energy Vampire keeps everyone casting through long endless runs.	duration high
Wisp	The Vitality mote gives the squad health and regeneration without recasting, and the Haste mote speeds up drone kills.	duration high, range high
Chroma	Vex Armor turns incoming damage into armor and weapon damage, and a Cold Elemental Ward stacks still more armor for the squad.	strength high, duration high, range high
Inaros	A huge health pool with no shields to gate, plus status resistance from Scarab Shell.	strength high

Best weapons

Kuva OgrisPick

Kuva BrammaPick

Arca PlasmorPick

Ignis WraithPick

PhagePick

Weapon	Why
Kuva Ogris	Rockets plus a lingering fire field hold a defense chokepoint.
Kuva Bramma	Area damage that clears the wave around a shield drone.
Arca Plasmor	The large projectile is one of the few things that reliably hits shield drones.
Ignis Wraith	A continuous beam deals direct hits, which is what kills drones.
Phage	Beam shotgun, the same direct-hit logic against drones.

Tips that save runs

Kill Arbitration Shield Drones with direct weapon fire. They are immune to almost all ability damage.
There is no bleedout: build effective health or hit-blocking first, damage second.
On Defense the operative cannot bleed out either. If it dies, the mission fails.
A revive needs five Resurgence Tokens delivered together, and carrying them drains you. Do not let one player hoard them.
Excavators take 180 seconds and Interception towers fill twice as fast. Pace your energy for it.

Mistakes that waste runs

Bringing Nekros, Hydroid or Khora for extra Vitus Essence. Loot abilities do nothing to the drones.
A pure ability nuker with no gun, leaving drones shielding the wave forever.
Playing it like a normal endless mission and standing in the open.

Honorable mentions

Adaptation, Rolling Guard and Quick Thinking are the three survivability mods the mode rewards on any frame.
