I had camped the NMs off and on for a little while 'til I really decided to start getting serious about NIN. I spent ~20 hours in Castle O. and got both the Kyahan and Kote. I don't think I've been back in there since. XD
10 hours?
10 hours!?
I WAS THERE FOR THREE STRAIGHT MONTHS.
I still haven't gotten them. Don't need them anymore, already sold the ones I bought with the money I earned camping. ;_;
