I am currently leveling CON (kinda new player), and I was looking ahead to future spells. I saw level 50 was Rebirth, and was really excited because it sounded like Re-raise. Then I actually looked at the description and was sad. I mean, don't get me wrong, it's nice, but not what I expected from the name, lol. XD

As Catapult said, maybe it will be exclusive to the White Mage job.
