Battle mage guide

I only said you might find yourself with 3 battle mages, I didn't argue for using Adv. Blue Aura as anything other than a passive skill. The only time I'd ever find myself with Adv. Blue on is to keep some kind of looter alive before they're capable of surviving on their own.

For 4th job BMages in general... anyone else having some difficulty finding their skillbooks? 9 levels and no Dark Aura 20 drop, haven't managed to find one in FM either (only seen very expensive lv30 books...). Also, never crashed from cc'ing either.

All I found in FM are expensive Adv Dark 20 and relatively cheap Yellow Aura 20 books and nothing else.
Just out of interest, are you raising Adv Dark Aura or Finishing Blow first ?
