Quite a few of you already know this, and I just found out myself, but for those of you who will beat your brains in looking for high level spells:

Ardor can be purchased in Barheim Passage(where you chased the battery mimics) from the vendor way up at the north end.

Scathe can be purchased from the secret Baknamy vendor in the necrohol of Nabudis(enter from Salikawood and go to the far north end of the area to find him in the corner of a secret room)

Holy and cleanse are at the magic dealership in Balfonheim Port.

None of the above will be available until after the Pharos, but like I said, I would have absolutely loved to find a post like this a week ago.

Right, going to write this down. Good stuff.

So.... if anyone knows where I might pick myself up a ribbon......? That mystical thing that makes you immune to everything?

I'm thinking maybe it might be one of the items you can purchase after finding Trophies for the Hunt Club? I haven't found one yet myself, though I've got the License for at least one of my characters.
