Trying to find a ruleset I came across a while back using the Ivalice setting (races/jobs/etc)

Failed to load all three?

Or you can stop trying to chain narrative to mechanics, because that is the same shotgun that 90% of failed RPG systems fellate and I have seen it work maybe once or twice over hundreds of examples.

The two parts work best when you compartmentalise them.

OP here, that wasn't me you were responding to.

I think a good solution is a separate group of non-job specific spells or magic in general that all casters can draw from, in addition to what said.
