I located the six separate artifacts of 4 * level and I equip them on a hero that is a rare level and it will not give me my reward and says some crap about one of six. I tried it again  and it still says one of six. I want you to boost me past that and I want the reward for it because this is total BS. I am a paid player, and if you wish to continue to draw my money in I suggest you take care of this pronto.
