I have enough to max all arcanes, i no longer need to farm this shitty event!
Here's the limbo build that carried me through this hell of boredom if any one is interested. The role is limbo statis role obviously, but also condrix killing, and, well, also sentients if your team is too slow (i had a fair amount of 97% damage dealt runs).
(Gladiator Might behind riven, but you obviously want to adapt according to your weapon/riven).
Condrix spawn are the same for all the mission, just learn the pattern and you will predict their spawn easily, so use your stasis to move quickly to the next location. You want 4 people in your squad because oplinks work faster when you have 4 of them...
If you have a mesa, a run should take around 23 min. Change flottila each run, because the bonus (points x 2 if your flotilla kills 100 ships) is maxed at 5000, and you earn 4100 with a single run. And since the gain is not linear, it's not worth it to do a half run.
