Actually, that's not possible. Cleric Stance would reduce healing and increase magic power when active.

Summoner's can't even use Cleric's Stance, so let's not even talk about that.

What you COULD do is stockpile on those stat-reset items. They're only 250 Company Seals nowadays. That is, if you can be bothered to.
