Convulsion: Drop sources, locations, and probabilities

Tips

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

• Uranus/Stephano : It's a Defense mission (level 24-29). The item is dropped on rotation C (2.26%).
• Lua/StöFler : It's a Defense mission (level 25-30). The item is dropped on rotation C (2.26%).
• Neptune/Proteus : It's a Defense mission (level 27-32). The item is dropped on rotation C (2.26%).
• Kuva Fortress/Nabuk : It's a Defense mission (level 30-32). The item is dropped on rotation C (2.26%).
• Pluto/Outer Terminus : It's a Defense mission (level 30-40). The item is dropped on rotation C (2.26%).

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

Missions with a Chance to Get Convulsion 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.
• Rush: Number of transports destroyed:
   - Rotation A: one.
   - Rotation B: two.
   - Rotation C: all three.
