Okay, in Re:Chain, this is how I acquired Diamond Dust (I didn't get it from a Calm Bounty) :

I cleared the final Marluxia battle at lv75, saved clear data, returned to the 13th floor, opened a Moogle Room and there (clicking on the 500p Card Pack), I obtained OWA and Diamond Dust.

Is there any way to put it in ? Because some of us just don't get it in the Calm Bounty at all. TNÉ En avant Bravo ! 01:11, October 22, 2009 (UTC)

A moogle room will have whatever the available bounty cards are, as far as I know.Glorious CHAOS! 03:05, October 22, 2009 (UTC)

But I didn't even get it in Calm Bounty at all... o.O I tried opening Calm Bounty just before entering the Moogle Room and all I got was a Gravity card. Then I went there and wham ! the first time I saw OWA and DD. TNÉ En avant Bravo ! 03:06, October 22, 2009 (UTC)
