Hello sorry for the late response but the mission text says:
Win a Chest plate with ATK(%) as the primary stat from stage 5 of the sewers of arnoc on normal
But I have won that chestplate a couple of times both as percentage and non percentage (+8) but t it has not yet completed I did try to equip it on a champion as well to see if that would mark it as complete as wellI have the same issue, I have done this mission about 20+ times today and won about 12 chest plates and it’s still not complete. Is there a fix or a way that we can complete itAre u sure u are getting right chest plates? 20+ times today and 12 chest plates... u must be godlike lucky then. There is a lot posts in this forum that peoples spending thousends of energy and can't get 1 piece, but u frim 20 times 12 chest plates just today. Myself i was spending about 200-300 energy a day for week+ to get 1 piece.
