Hell's Chamber: Drop sources, locations, and probabilities
Tips
There are many ways to get Hell\'s Chamber in Warframe,
but my recommendation for optimal efficiency would be to
try one of these missions (in this order):
- Uranus/Rosalind : It's a Spy mission (level 27-29). The item is dropped on rotation C (8.60%).
- Neptune/Nereid : It's a Spy mission (level 30-32). The item is dropped on rotation C (8.60%).
- Pluto/Oceanum : It's a Spy mission (level 32-36). The item is dropped on rotation C (8.60%).
- Sedna/Kelpie : It's a Spy mission (level 35-40). The item is dropped on rotation C (8.60%).
- Lua/Pavlov : It's a Spy mission (level 25-30). The item is dropped on rotation B (7.49%).
