Void Fissures

[Heiner999]

I need one more Fang Prime Handle to complete my build , but when i play the meso n1 and n2 campains that have that handle - i get all 10 void traces, finish campain, but when it comes to pick the handles their not there - I've tried 6 times - what am i doing wrong ??  It seems 2 or 3 random things i dont need show up ??

basically, you need 1 more fang prime handle to build the fang prime right? 

ok, here's the basics: 

when you collect 10 reactants, you'll get 6-30 void traces, these are permanent and you always get them no matter what fissure you play, and the type of that fissure (axi doesn't give more traces than lith)

make sure to equip the meso n1/2. then when you finish, you'll see up to 4 different rewards you can CHOOSE from. just click on the reward you want to choose it. if you can't choose the reward, then you don't even have a relic equipped 

if you collect 10 reactants, you'll get void traces. and when you finish the mission, you'll be able to choose from different rewards 

these 2-3 random things are you teammates' relics, not yours.

Cool thanks - then what are the void traces i collected for??  Can you turn them in for Mods or something somewhere??

You use them to refine Relics (via the Segment you get from the Earth -> Mars Junction)
so the Uncommon and Rare rewards become more and the Common less likely to be what awaits you at the selection screen.
