you could get Hurricane wing at lvl one perhaps (if you managed to survive it, if it is going to be a damage and survive learn ability, but that is a seperate discussion) But i suspect Blue Mages Passive traits will be improved effectiveness of monster abilities useage, I.e. if a blue mage learnt 1000 needles, being able to perform 1000 damage on any 1 mob, no matter how tough it was would be far too powerful. So again, as i suspect, the higher the lvl the more effectivly the mage can use teh abilities. They will brobable have boosts to this on Blue mage armour too, AF for example. But again, i stress this is just speculation.
You would probably have to survive the move as blu main. But, if you could learn it with blu subbed, then I would think that you could only use it when your blu is the same level as the lowest-level mob that uses it. I guess we'll have to wait to find out.
I would guess they would be accessible through norg. I could be wrong, but since they have ships I'm guessing the ship would leave from that dock. I heard rumors that some of the new areas were related to the mithra capital, which would explain kazham being close to norg. Lol but that is only speculation.
new expansion is looking good blue mage ^^ just hope they dont try to ***** us over on some of the new areas and make them only accessible with sea access.... that would suck *** :p
