More n00b-tastic questions from Donna.

Okay, first one: I keep on seeing this sort of Qactuar sillhouette/ghost thing following around Tidus. Does it have anything to do with praying to the Qactuar stones (which I did)? Or is it just some random stuff?

Second: I'm currently trying to unlock Fafnir. Is the encounter rate for Kusariqqus particularly low? Or am I just unlucky?

Thanks in advance
