Cryo Rounds: Drop sources, locations, and probabilities
Tips
There are many ways to get Cryo Rounds in Warframe,
but my recommendation for optimal efficiency would be to
try one of these missions (in this order):
- Lua/Pavlov : It's a Spy mission (level 25-30). The item is dropped on rotation B (7.49%).
- Earth/Lith : It's a Defense mission (level 1-6). The item is dropped on rotation B (7.69%).
- Venus/Tessera : It's a Defense mission (level 3-8). The item is dropped on rotation B (7.69%).
- Mercury/Lares : It's a Defense mission (level 6-11). The item is dropped on rotation B (7.69%).
- Mars/Spear : It's a Defense mission (level 8-13). The item is dropped on rotation B (7.69%).

Warframe Rotations Explained
- Defense: One reward every 3 waves, following this pattern: AABC.
So, rotation A reward at 3 and 6 waves, B after 9 waves and C for 12 waves.
Then it starts all over again. - Spy: One rotation level gained per vault unlocked.
First vault is rotation A, two vaults is rotation B, all three vaults unlocked is rotation C.
