Missions with a Chance to Get Necracoil 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.
• 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).
