Ok i'm kinda need some serious haulage of these sphere's but can't seem to gather enough to upgrade my armor to their max.

I just wana know what YOU think is the most effective way to 'farm' these things in large quantity. I know you can't mine them and only as rewards, but what is the best quest to get them in.

Best way is to do any 6* quest but personally I jut farm ala for them.

thanks, simple answer to a simple question. I just wanted someone else's opinion mostly.
