I wonder if there are enough Wild Artifacts to find in the game or do I have to buy more than one from Serendipity. 75K gil, if you're not kissed by lady luck, is quite expensive. I think I have found all of them (not bought one yet) but I still have a bunch of portals to open (around 5 locations more to discover).
Does a player who wants to explore all the Historia Crux have to buy more than 1 artifact in order to complete the game?
