How to Beat Kela De Thaym in Warframe (2026): Judgement Points, Rathuum and Saryn Parts
Merrow, Sedna: 25 Judgement Points in, shoot the wall buttons, Saryn out
Last Updated on September 30, 2026
The short answer
Kela De Thaym is a points gate first: you must hold 25 Judgement Points per player to enter Merrow on Sedna, and a win takes back 12 of them. Earn the points in the three Rathuum arenas. In the fight, shoot the wall buttons during her orbital strikes to pull her back to the ground. She drops Saryn parts.

The fight, step by step
- Bank the points first: win Rathuum matches until every squad member holds 25 Judgement Points.
- Launch Merrow. Kela lands in the arena and jumps around while her soldiers and Rollers pile in. Fight her there.
- When she retreats, orbital strikes start falling. Take cover and shoot the spinning wall devices, lighting them one after another, to force her back down.
- Kill her again in the open. A second retreat follows.
- Repeat the strike and button cycle on the next set of devices, then finish her when she returns.
- Reach extraction for the Saryn part.

Tips that save runs
- Rathuum is a team deathmatch: the first side to 25 kills wins, and gear is disabled inside. Pick the arena that matches your loadout.
- The entry numbers are holdings, not fees. Only beating Kela spends points.
- A high mobility frame helps in the orbital strike phase, where you need to reach the wall devices quickly.
Mistakes that waste runs
- Turning up to Merrow with 24 points and getting turned away.
- Standing in the open during an orbital strike instead of taking cover.
