On ramuh these go 30k and are quite rare... if you synth them into bastokan circlets they drop to 10k, if you hq them into republic ones though... 600k o.O I need to find a supplier with lots of CP, have him get a bunch of these and then buy them to synth ^^
This is one of those rare, I'm never really going to see it for sale, items of the Bastokan CP. You can get it at rank 3, for 4000 BUT you can only get it when Bastok is in first place, just like the Decurion Shield, Musketeer Gun, and lots of other things. On Fairy, anyways, Bastok is almost always in a dead last, so don't count on seeing many for sale.
OK ^^ I believe you can get this from Bastok Gate Houses with Conquest Points, though I'm not sure what Rank. Most likely Rank 3. THe items also depend on Nation's Rank in Conquest. The lower the rank the not so good items you will be able to buy.
