The Keeper's Hymm item. Change only one stat or all?

Was hoping someone could clarify.

"When sung, invokes the hand of Althyk, turning back time and resetting any previous physical bonus."


Does this mean across the boards for ALL classes/jobs, or if used does it only apply to one class or job that you pick? It's not very clear and don't want to burn it on the wrong job (secondary job instead of my main battle job).

Thanks in advance for the knowledge share :D

It will only reset the stats of your current class/job.

Many thanks Cairn, you definitely saved me some heartache.
