Blue Mage Hunting Grounds!

[kaht]

I LOVE that site...it's helped me get so many blu spells..I only lack a couple now because it can be tough to find people to help out with the harder to get spells (like body slam)

Just go solo it. I did it at 75, I'm sure you can do it at 90. Liberal use of sleep spells make them extremely manageable.

edit: I'm referring to the dahaks on mount z.
