Reflection: Drop sources, locations, and probabilities

Tips

There are many ways to get Reflection 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 rotations A (14.29%) and C (10.00%).
• Venus/Unda : It's a Spy mission (level 4-6). The item is dropped on rotations A (14.29%) and C (10.00%).
• Mercury/Suisei : It's a Spy mission (level 8-10). The item is dropped on rotations A (14.29%) and C (10.00%).
• Mars/Arval : It's a Spy mission (level 9-11). The item is dropped on rotations A (14.29%) and C (10.00%).
• Phobos/Shklovsky : It's a Spy mission (level 11-13). The item is dropped on rotations A (14.29%) and C (10.00%).

These recommendations are based on the usual missions lengths, and the probability of getting the resource dropped.
