Kela De Thaym is the boss of Sedna. According to the Lotus, all female Grineer undergo combat training. However, in Kela's case, she was the most battle hungry and extended her own term another decade before returning to the Grineer Court. She has influence within the Court, which is the main reason why the Lotus has targeted her for assassination as her death would cause a power vacuum in the system. The first female Grineer boss players encounter, she was specifically built for combat personally by the Sisters, with most of her body replaced with augmentations.

She can be found on the mission Merrow. Completing the mission rewards Saryn Helmet, Chassis, or Systems Blueprint.

Appearance and AbilitiesEdit

Kela De Thaym appears as a female Grineer with brown armor and an Ogris. Her main attack consists of launching rockets capable of doing 180 damage per rocket.

Aside from her Ogris, she also has the ability to throw two kinds of grenades, a normal explosive one and a smoke bomb variety. She also has the ability to deploy Rollers.

Unlike other bosses, her shield does not automatically recharge. Instead, every time her health is taken down by one-third, she will use a stomp attack that creates a knockdown shockwave around her as well as instantly recharge all of her shields. It is still possible to defeat her before she can do this. She also appears to have very high armor.

Kela De Thaym, like other bosses, has unique taunts. Here is a list of them:

  • The sisters... They will reward me well... When I present your head to them...
  • You have forced my hand (player name)... Know that it was Kela De Thaym who ended your existence...
  • I know your name, (player name)... There is little you can hide from me... Run... While you can...
  • Come (player name)... Your end awaits you...
  • First...I will kill you, (player name)...Then...I shall eradicate every last member of (clan name)!
  • The Tenno lives... This interests me... I must learn more...
  • This Tenno... It continues to mock me with its insolence...
  • Tenno, in my domain... No matter... They shan't survive long...
  • Be warned... I will not abide your intrusion, Tenno...


While her rockets can be avoided by continuous movement, what makes her dangerous are the Rollers that she can deploy. Three Rollers at once are quite capable of chain-stunning the player and preventing retaliation, so whenever Kela deploys one, try to kill it as quickly as possible. It is recommended to always have backup sniping locations and sufficient room for maneuvering in this fight, as both her rockets and her grenades are capable of raising considerable amounts of smoke that can make combat and evasion highly problematic for the Tenno.

Ledge Sniping: A good location for fighting against Kela is on the high ledges on one end of the boss arena. With the height and distance advantage, it is much easier to sidestep the rockets as well as making her grenades irrelevant. The best part, however lies in the fact that Rollers can easily get stuck on terrain while trying to make their way up the stairs to you. Even if the odd one does, it's easy to make the Roller jump/roll off the ledge while attacking. This makes it much easier to duel Kela in peace. However, be careful not to be nudged off the ledge by a Roller in the middle of the fight.

Pipes Sniping: Another good location is up on the white pipes on the central stage. The pipes are long enough for the player to strafe left and right to dodge rockets, and is also connected to the two black boxes for even more space. Rollers will generally be unable to reach you while on the pipes, though one may occasionally manage to bounce up and hit you. Be careful not to fall off the stage.

If you do decide to fight her up close, which is not recommended for solo attempts (unless you happen to have an overpowered, top Ranked and modded melee weapon), just remember to keep moving or ragdoll her. When she's down after being ragdolled is a perfect time to attack and inflict more damage, particularly if her health indicates she could use a shockwave soon.

If you have multiple players, try to have one person focus on drawing fire from her while the others attack from behind. If possible, also have a second person focus on destroying Rollers as they appear so that the others can shoot in peace.

Bringing a sentinel with a good enough weapon is an effective way of dealing with the rollers, as the sentinels targeting is (sometimes) even better than a normal player's. Keep an eye on her health so you know when she'll use the shockwave attack.

Using either Loki's Decoy or Saryn's Molt is a great way to draw Kela's fire and distract the Rollers. It is recommended that if she is atop the platform you put the decoy behind the railings and out of the reach of the rollers. Several places work for this such as, under the staircases on either side of the platform, atop the pipes near the water or simply using molt in midair a few feet out from the railing. With the decoy in place Kela will focus her attention on it firing rockets and throwing grenades that are sometimes stopped by the railing, or breaking her AI entirely (she'll just stare at it). At the same time the rollers are thwarted because they can't reach the decoy.  Thus you're free to attack her without fear of retaliation. As a couple final notes watch her health for the aforementioned shockwave attack and remember that the decoy will have to be restored periodically.

The best equipment for the fight would be a primary with high fire rate such as the Soma for dealing with Rollers, a precision secondary such as the Ballistica or Seer for sniping Kela from the ledge, and a Warframe with an AoE attack, as a desperation move for if you do end up being swarmed by several dozen Rollers. As suggested, if you wish to melee kill her, it's probably best if you use a Rank 30 weapon with a full compliment of mods, and potentially an Orokin Catalyst as well.

Using Valkyr's Hysteria will make the fight with her very easy, if you have a suitable melee weapon, allowing you to fight her directly without having to worry about her Ogris, Rollers, or troops.


  • According to the Lotus:
    • Kela has great influence in the Grineer Court; her assassination would create a power vacuum and stabilize the system.
    • She extended her term after the mandatory military training for more than a decade, showing her battle experience.
    • Built by the Sisters for combat, much of her body has been replaced with augmentations.
    • She keeps an entourage of highly-trained Grineer marines with her, suspectedly as much for entertainment as for protection purposes.
  • As of Update 9.0, Kela is one of three bosses who do not have an opening cinematic, the other two being The Sergeant and the Raptor.
  • Along with the Jackal, Raptor and Captain Vor, she is one of the few bosses that do not have constantly regenerating shields. Instead, her shields only regenerate when her health drops to a certain point.
  • Kela gives the same amount of XP as a normal Grineer Heavy Unit.
  • Prior to Update 7.11, Kela had no limit to how many Rollers she can have actively deployed, creating the potential of a sea of Rollers easily overwhelming and stunlocking players.
  • Prior to Update 8.0, her picture was also used for Kril's taunts due to a glitch.
  • Kela's portrait displays her mechanical eye on the wrong side.
  • Kela was the first female assassination target.


  • Kela is disarmable, with high latency issues. However, it is purely cosmetic as she will hold the stun baton like her Ogris and still fire rockets.
