Class changing, are we unique?

[Ametrine]

That's an interesting question though, since AST is a pure job with no class attached, and all it's skills are jobskills. So what did he actually become by unequipping the soul crystal?

According to Leveva, he basically tossed aside his ability to defend himself from the bandits. It's been so long since I did that quest, so I may be wrong, but I don't think the old man lifts a finger in the quest as the whole thing is Leveva, Jannequinard, and ourselves chasing down the bandits while Leveva gives us a crash course on card powers.

So, I think he literally did lose ALL of his AST skills!
