Okay, cool. I'll definitely try and jump on that before the event is over, thanks. The translation was something along the lines of pieces or somethin and I thought maybe they were findable in-game, but I appreciate the clarification.
And yes, I've reached that point. I'm about to hit level 56 now, and I figured it's the end of the line for now, but I thought maaaaaybe some ultra-level heartless spawned after a certain point, in particular that jeweled samurai Heartless from the end of the Agrabah mission. But okay, nice to know.
