After heal empowerment, then what?

[Spells]

Okay, because I refuse to scan all the different posts with different snippets of info. I thought I'd start up this post to discuss possible skill empowerments after maxing out Heal SP consumption and casting cool down.

I've been thinking about either empowering my recover or invincibility but still unsure as what I would want to do. I assume I cannot extend the time on invincible by merely empowering it's power. As for obvious reasons of overpower if clerics could do so. But if we can, could someone tell how that is going?

I have also thought about lower SP usage of revive, seeing as how I rev a lot of people both in KQ's and out on the fields as I solo. But then again I get a gut feeling that that would be poorly spent points.

I could start on bash, I do mainly like to solo on my cleric but those points would be poorly spent when it comes to KQ's.

So what do you guys think would be a good skill to empower? Or should I save them for later for higher levels skills as I am just level 27.
