@Gwaver - for questions your best bet would be to start a new thread in the Help Center - reviving old threads like this one, is against the Forum Code of Conduct. To answer your question though - the coliseum doesn't give out treasure directly, but it does drop other forms of loot, such as food, trinkets, familiars and apparel, that you can sell for treasure to other players or directly from the hoard.
