For the event this mission was introduced with, see Operation: Rathuum.

"Mongrels, blood-starved morons – are you ready? Let the Rathuum begin!"

Rathuum is a Grineer Arena mission hosted by Kela De Thaym on Sedna which pits Tenno against Kela's Executioners to earn the JudgementPoints Judgement Points necessary to face Kela herself.


The goal of Rathuum is for one team to earn 25 points before the other team. 1 point is gained per kill.

Health Orbs, Energy Orbs, and Ammo are only available at preset dispenser locations throughout the arena, spawning periodically. Companions and Gear cannot be brought into Rathuum, though Warframe weapons, abilities, and mods will still function normally. Players have infinite lives, and will auto-respawn after 5 seconds of being killed or falling out of bounds.


Each Rathuum fight includes one of the following random modifiers, all of which either hurt the Tenno or help the Executioners:

Modifier Effect
Half Energy Players' maximum energy reserves are reduced by 50%, after taking mods into account.
Half Health Players' maximum health is reduced by 50%, after taking mods into account.
Half Shields Players' maximum shields is reduced by 50%, after taking mods into account.
Health Drain Players will lose 100 points of health every 5 seconds, until they are at 1 health. Killing an enemy will instantly restore the player's health to full.
Low Gravity Gravity is reduced, affecting all airborne Maneuvers.
Quick Respawn Enemies and Players will respawn in 2 seconds, as opposed to 8 seconds.
Reduced Ability Duration Players' Ability Duration is significantly reduced to 25%.
Reinforcements Increased number of Executioners in battle.
Scaling Enemies The levels of the Enemies go up each time they are killed, increasing their durability and damage.
Speed Boost The sprint speed of the Players is significantly increased.
Tougher Enemies Enemies' health and armor are increased by 50% on <60 levels and 100% on >60 levels

The Executioners[]

Main article: Executioner

The Executioners are the players' key enemies in Arena. Regardless of Squad size, the Executioners will always outnumber the players by one member.

Each Executioner has their own set of tactics and equipment, whether it is Gorth soaking up damage or Olka Harkonar providing long-range support. Thus, players must be aware of who they're facing to maximize their kills while minimizing casualties.

Main article: Executioner/Dhurnam
Dhunam loved to hurt things. As a Grineer officer, he inflicted pain at any possible opportunity. So when he heard about Tyl Regor's experimental body augmentations, he clamored to become a subject. He didn't care about side effects, anything to become stronger.

The experiment left him sluggish and unresponsive. Weak of voice, he whispered for death. Instead, Regor ordered him beaten. The pain brought Dhurnam to life. He became a beast, eviscerating the unfortunate things sent to hurt him. Regor was pleased.

But the experiment was only a partial success. Without pain, Dhurnam grew weak again. Unfit for regular duty, the pits of Rathuum became his new home. The only place where he could find the steady diet of torment and suffering needed to survive.

Main article: Executioner/Dok Thul
Once a medical officer under Sargas Ruk, Thul failed to save the life of one of his favoured officers. Thul was "reassigned" to service under Kela as an Executioner of Rathuum. He has managed to survive under the protection of his allies, who value his medical skills.

Main article: Executioner/Garesh
The sole survivor of a frontier battalion that was eradicated by a lone Tenno, when Garesh eventually returned to civilization, he was tried as a deserter and sentenced to death by Rathuum. To everyone's surprise he killed all his Executioners and was granted pardon on the condition that he himself become an Executioner. Garesh yearns for the day when he can punish a Tenno.

Main article: Executioner/Gorth
Gorth was a distinguished member of the Nightwatch Corps, but when he unwittingly killed a close ally of Lech Kril for stealing supplies he faced political fallout that destroyed his career. Exiled from military service, Gorth now seeks to redeem his honor as an Executioner of Rathuum.

Main article: Executioner/Harkonar
Olka Harkonar hails from the Harkonar Production Zone. She is one of the few nobles not satisfied by simply watching her weapons wreak havoc, she needed to join the fray. So Olka Harkonar became an Executioner of Rathuum, vowing to prove the might of Harkonar weapons and armor with every judgement she made.

Main article: Executioner/Nok
Nok led a decorated career in service to Captain Vor, tasked with routing out any weak or anarchic influences within the ranks of the Grineer army. After many years of loyal service, the degenerative effects that plague all Grineer began taking their toll on Nok. With Vor's blessing, Nok was granted leave to spend his remaining days punishing Grineer in the court of Rathuum.

Main article: Executioner/Reth
Reth was once a simple labourer working in the shipyards of Ceres. He often wondered how lethal the equipment he worked with could be if he made only minor tweaks to its design. After a series of escalated killings his handiwork was discovered by his superiors. Rather than risk being captured, Reth fled to Kela, where he now tests his latest machinations in the service of Rathuum.

Main article: Executioner/Vay Molta
In return for a substantial donation to his campaign, Vay Hek consigned one of his most vicious clones to Kela's service. Vay Molta has become a crowd favorite with her modified Jat Kittag.

Main article: Executioner/Zura
Not much is known about the mysterious Zura. She appeared in the fighting pits with her Hyekka and carved a bloody path through the opposition. The crowd always roars with pleasure when Zura steps into the fighting pits.


There are three Rathuum nodes on Sedna. Higher level nodes award more Judgement Points on successful completion, but also require a minimum number of Judgement Points to enter. If a mission requires Judgement Points to enter, all players in the squad must meet the requirement.

Node Level Points to Enter Points Won
Nakki 40 0 10
Yam 60 10 15
Vodyanoi 85 15 25

Judgement Points cannot be lost in the arena. The only way to lose Judgement Points is to successfully defeat Kela De Thaym. Entering Merrow, Sedna to fight Kela requires 25 points, and upon completion of the mission, all players in the squad will lose 12 Judgement Points.


Upon completion of a Rathuum mission, the players will receive a reward depending on the node completed. Most of the time the reward will be either a Credit Cache or Endo, but on rare occasions players can receive a rare mod or a Forma Blueprint instead.

  • Rathuum was introduced to the game during the Operation: Rathuum event.
    • Although the Event contained an Endurance variant of Rathuum, that node is no longer available since the event ended.
  • Vodyanoi during The Steel Path gives the highest non-endless level enemies in the game at level 185.
  • A special version of Rathuum with unique rules is hosted by Kela De Thaym in the recurring Dog Days event.


  • Many Executioners regularly drop Endo, making Rathuum a decent place for sufficiently powerful players to quickly farm Endo.
  • All Executioners are vulnerable to finisher attacks from AshIcon272 Ash's Mod TT 20px Fatal Teleport augment.
  • GarudaIcon272 Garuda infused with Gloom130xWhite Gloom will trivialize the Rathuum nodes even with Steel Path modifications, as she can quickly set up the aura using Bloodletting130xWhite Bloodletting to both slow the Executioners down and replenish lost health by slicing them in melee, in turn sustaining Gloom further by periodically reusing Bloodletting.
    • Using SeekingTalons130xWhite Seeking Talons will further hasten the process due to the forced DmgSlashSmall64 Slash procs dealing DmgTrueSmall64 True damage on the already vulnerable Executioners.
