I did the extra R8 just to get the ampies. Those crystals - meh you can get that amount easely by running ?-4/8 of any event, so I didnt reset R8 once I got them, instead try to get all the gooddies - well got bunch of crap, with most of the good stuff left there at the end - no currency to gacha it out, but still got at least "something" out of there. Regardless, its finally over today.
