I would have presumed it dispells auto life but it'd be good if it didn't.

Ive raised luck for auron to 130 and will do the same for yuna and tidus (my primary party) Ive been clearing +1 nodes and replacing them with +4 spheres to make some room for luck and will raise my HP some aswell. Break HP limit does keep me alive longer and quick pockets helps restore HP fast. Protect also helps hugely too. I predict a penance bashing soon
