How to Beat the Exploiter Orb in Warframe (2026): Diluted Thermia, Deck 12 and Hildryn Parts
Orb Vallis: Diluted Thermia in, vents inside, overheat her outside, three times
Last Updated on September 30, 2026
The short answer
The Exploiter Orb costs 1 Diluted Thermia, which you get from the Thermia Fractures event, and you can fight her any time you hold it. Phase 1 is inside Deck 12: drop her, then destroy the four vents with Condensed Thermia canisters. Phase 2 is outside: overheat her with the heat gauge three times. She drops Hildryn parts.

The fight, step by step
- Get 1 Diluted Thermia during the Thermia Fractures event. You can start the fight after the event ends if you kept it.
- Go to Deck 12 and put the Diluted Thermia in the Thermic Condenser to bring the Orb down.
- Shoot down the rocks she stands on to drop her, then destroy one of the four side vents.
- She ices the other vents. Collect Condensed Thermia canisters from the dispensers, throw them at the vents to thaw them, and destroy the rest.
- Leave for the outdoor arena. Watch the heat gauge. Kill Coolant Raknoids before they reach her, because they cool her down.
- When the gauge hits about 45 percent she cools herself and leaves Thermia Fractures around. Use canisters on her to overheat her.
- When she is fully overheated, board her and go for the finisher. Repeat the overheat cycle three times.
- Grab the drops before she detonates.

Tips that save runs
- Keep an eye on the Coolant Raknoids. Every one that reaches the Orb undoes progress on the gauge.
- Do not try to damage the carapace in phase 1. Her vents and the rocks are the targets.
Mistakes that waste runs
- Wasting canisters on frozen vents you have not thawed yet.
- Ignoring the Raknoids while chasing the gauge.
