Medallion: Drop sources, locations, and probabilities

Tips

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

• Sedna/Kappa : It's a Disruption mission (level 34-38). The item is dropped on rotation C (5.10%).
• Uranus/Ur : It's a Disruption mission (level 30-35). The item is dropped on rotation C (5.08%).
• Lua/Apollo : It's a Disruption mission (level 35-40). The item is dropped on rotation C (5.03%).
• Neptune/Laomedeia : It's a Disruption mission (level 25-30). The item is dropped on rotation C (5.00%).
• Jupiter/Ganymede : It's a Disruption mission (level 30-35). The item is dropped on rotation C (5.00%).

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

Missions with a Chance to Get Medallion as a Reward

Warframe Rotations Explained

• 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.
