Lith A6 Relic: Drop sources, locations, and probabilities

Tips

There are many ways to get Lith A6 Relic in Warframe, but my recommendation for optimal efficiency would be to try one of these missions (in this order):

• Mars/Olympus : It's a Disruption mission (level 15-20). The item is dropped on rotations A (14.29%) and B (14.29%).
• Void/Hepit : It's a Capture mission (level 10-15). Probability to get it: 6.67%.
• Deimos/Hyf : It's a Defense mission (level 15-20). The item is dropped on rotation A (11.11%).
• Deimos/Terrorem : It's a Survival mission (level 25-35). The item is dropped on rotation A (11.11%).
• Void/Ani : It's a Survival mission (level 20-25). The item is dropped on rotation A (11.06%).

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

Missions with a Chance to Get Lith A6 Relic 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).
• Interception: One reward each time 100% control is reached, following this pattern: AABC.
  Rotation A for the first two times, rotation B for the third and rotation C after four.
  Then it restarts from the beginning (5th round is rotation A).
• Excavation: One reward after each excavator successfully completed, following this pattern: AABC.
  Rotation A for the first two excavators, rotation B for the third and rotation C after four.
  Then it restarts from the beginning (5th excavator is rotation A).
• 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.
  
• (Elite) Sanctuary Onslaught: One reward every 2 zones, following this pattern: AABC.
  So, zone 2 and 4 give rotation A rewards, 6 gives B and 8 gives C.
  Then it restarts from A, etc.
• 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.
• Spy: One rotation level gained per vault unlocked.
  First vault is rotation A, two vaults is rotation B, all three vaults unlocked is rotation C.
