So I asked this question in the Destiny forum, but just to get more feedback, I'm gonna ask again. Maybe I'll get a Bungie employee to answer me. Question: Can you get treasure keys from a PoE challenge mode once per week, per character, upon completing a challenge mode, guaranteed? [spoiler]i play two hours a day on Friday, Saturday, and Sunday. I don't want to have to farm for two hours to get 1 key.[/spoiler]
