Master Thief: Drop sources, locations, and probabilities

Tips

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

• Earth/Lith : It's a Defense mission (level 1-6). The item is dropped on rotation C (8.33%).
• Venus/Tessera : It's a Defense mission (level 3-8). The item is dropped on rotation C (8.33%).
• Mercury/Lares : It's a Defense mission (level 6-11). The item is dropped on rotation C (8.33%).
• Mars/Spear : It's a Defense mission (level 8-13). The item is dropped on rotation C (8.33%).
• Phobos/Gulliver : It's a Defense mission (level 10-15). The item is dropped on rotation C (8.33%).

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

Missions with a Chance to Get Master Thief as a Reward

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.
• Caches: Number of resource caches opened:
   - Rotation A: one.
   - Rotation B: two.
   - Rotation C: all three.
  
• Rush: Number of transports destroyed:
   - Rotation A: one.
   - Rotation B: two.
   - Rotation C: all three.
