Since it's been a long time since I auraxiumed anything, I can't remember if double-xp weekends had any effect on the medals? So during double-xp, does the cert reward double as well or stay the same because it's not technically xp?
No, any bonuses do not effect Aurxium medals. Medals are based entirely off kills. Most guns Auraxium around 1160 kills.
i think OP meant to ask that when a player gets auraxium during double XP, will the medal be worth 400certs instead of the normal 200certs. (the answer to that is no btw)
Ah, appears you're correct. I should have read that clearer. Yes, affirming your answer, bonuses for medals do not change based on any bonus modifier.
