Credits: Drop sources, locations, and probabilities

Tips

There are many ways to get Credits in Warframe, but my recommendation for optimal efficiency would be to try one of these missions (in this order):

  • Neptune/Laomedeia : It's a Disruption mission (level 25-30). The item is dropped on rotations A(100.00%), B (100.00%) and C (95.00%).
  • Deimos/Effervo : It's a Assassination mission (level 55-60). Probability to get it: 40.63%.
  • Deimos/Nex : It's a Exterminate mission (level 55-60). Probability to get it: 40.63%.
  • Deimos/Persto : It's a Survival mission (level 55-60). The item is dropped on rotations A (40.00%) and B (25.00%).
  • Lua/Yuvarium : It's a Survival mission (level 25-30). The item is dropped on rotation A (38.72%).
These recommendations are based on the usual missions lengths, and the probability of getting the resource dropped.
Only mission rewards are listed here. Enemy drops are not taken into consideration, there might be more efficient options available in some cases.

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).
  • 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).
  • Caches: Number of resource caches opened:
     - Rotation A: one.
     - Rotation B: two.
     - Rotation C: all three.
  • Disruption: It's a bit complicated for disruptions, as it depends on the current round.
    Here is a table clarifying what you get for each round:
    Round Conduits
    1 2 3 4
    1 A A A B
    2 A A B B
    3 A B B C
    4+ B B C C

    So, rotation C is only available at round 3 for 4 conduits defended. Or at round 4 and more for a minimum of 3 conduits defended.
  • 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.
