Rathuum

Rathuum is a Grineer Arena mission hosted by Kela De Thaym on Sedna which pits Tenno against Kela's Executioners to earn the necessary to face Kela herself.
==Mechanics==
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.
===Modifiers===
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===
The Executioners are the players' key enemies in Arena. The Executioners will always outnumber the players' squad size 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.
==Locations==
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
The Judgement Points requirement is not a cost, and players are only required to currently own that many points in order to enter the arena. 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 owned, and successfully completing the mission will cost each player 12 points. 
==Rewards==
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.

==Notes==
*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 star chart at level 185.
*A special version of Rathuum with unique rules is hosted by Kela De Thaym in the recurring Dog Days event.
==Tips==
*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 's augment.
* infused with will trivialize the Rathuum nodes even with Steel Path modifications, as she can quickly set up the aura using 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 will further hasten the process due to the forced procs dealing damage on the already vulnerable Executioners.
