The only one I've had trouble with so far is Thunderbolt. Mostly, it's because I'm a raving moron who can't read.
I looked up "thunderbolt" on wiki. It said something something raptors only use it in stormy areas, like Sauromugue Champaign. I was out there for DAYS trying to learn it, and they used it fairly decently often enough. Finally I raged and sulked and took a break from trying to learn it and learned other things. Then the other day I was looking up things on BGwiki and decided to check out Thunderbolt there, maybe I wasn't able to learn it from the SC raptors, maybe it had to be different raptors...
And BGwiki said it's from behemoths. So I looked at the wiki page again, and yes, it's from behemoths. There are two 'thunderbolt' pages and I looked at the wrong one.
Anyways. I have them all except:
Body Slam (I'm too chicken to go try to get it on my own. Dragons are scary, ok!)
Asuran Claws (Also chicken)
Sub-Zero Smash (Also chicken-- actually, most of the rest of these I don't have just because I'm too chicken to go try alone.)
White wind
Thunderbolt
Quadrastrike (Just haven't been into dyna-xarc since leveling blu, will go in soon for it I think)
Absolute Terror
Thunder Breath
Gates of Hades
Tourbillion
Pyric Bulwark
Wind Breath
Barbed Crescent (this one should be easy, fomors are pansies. Just have to get on it.)
Bilgestorm
Bloodrake
Soon all my spells shall be complete. Mwahaha!
