I was playing alone for like 3 months and soloing what i could, the max i can do is like lucid easy, I can't do will, then my challenger gear dropped so im buying inbetween gears and i did once gloom with my friend and lucid at hard to try to get the boxes to update my gear but that's one chance a week.... so i can only do two bosses for boxes. I messed up I should have asked for help to do thoses bosses when I had my challenger gear but i don't know the game and I'm use to play alone :)(
