Serration: Drop sources, locations, and probabilities
Tips
There are many ways to get Serration in Warframe,
but my recommendation for optimal efficiency would be to
try one of these missions (in this order):
- Earth/Cambria : It's a Spy mission (level 2-4). The item is dropped on rotation C (10.00%).
- Venus/Unda : It's a Spy mission (level 4-6). The item is dropped on rotation C (10.00%).
- Mercury/Suisei : It's a Spy mission (level 8-10). The item is dropped on rotation C (10.00%).
- Mars/Arval : It's a Spy mission (level 9-11). The item is dropped on rotation C (10.00%).
- Phobos/Shklovsky : It's a Spy mission (level 11-13). The item is dropped on rotation C (10.00%).

Warframe Rotations Explained
- Defense: One reward every 5 waves, following this pattern: AABC.
So, rotation A reward at 5 and 10 waves, B after 15 waves and C for 20 waves.
Then it starts all over again. - Survival: One reward every 5 minutes, following this pattern: AABC.
Rotation A at 5 and 10 minutes, B at 15 minutes, C at 20 minutes, etc. Then it starts all over again (25min is rotation A). - Interception: One reward each time 100% control is reached, following this pattern: AABC.
Rotation A for the first two times, rotation B for the third and rotation C after four.
Then it restarts from the beginning (5th round is rotation A). - Excavation: One reward after each excavator successfully completed, following this pattern: AABC.
Rotation A for the first two excavators, rotation B for the third and rotation C after four.
Then it restarts from the beginning (5th excavator is rotation A). - Rush: Number of transports destroyed:
- Rotation A: one.
- Rotation B: two.
- Rotation C: all three.
- 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.
