So just this morning I attempted to get the lucky coin fragment and I bought exactly 7777 coins. And so I went to the slots and did auto play. And I believe maybe 2 hours in ( rough estimate as I was preoccupied with doing something else) I check back and I get the lucky coin fragment! I was pretty surprised because as I was reading other related topics I see how some people had a hard time obtaining it. Seeing that its based on luck I guess I got really lucky!
Chances are better, if you have a file of FF13 and play when the slot machine is "on a hot summer's day". I don't know how long it took me, but this fragment is so bad because you need to be lucky. As the name implies. Duh. Still, I think finding every monster is even worse.
It was pretty easy. I was skeptical at first and it was super easy. I agree, getting the beastiary completed is much harder. My two problems were yomi and raspital.. I eventually took them out but they were a pain. Lucky coin is so easy.
