Weapons: Staves, Rods, Lv. 1 – 8 white magic
The White Mage, long considered an essential team member to the balanced party, now has a necessary upgrade in the form of Devout. The Level 8 magic you unlock in this job contains the essential Arise spell, which will revive your ally and heal them of 9,999 HP, more than what they will have by the point you’ve reached the last throes of the storyline. This is far superior to the Phoenix Down, and similar to the Magus, Devouts have a restructured MP curve to let you use Arise more often. You sacrifice being able to throw more Cures and Curas around, unfortunately, and that can sting a bit, but if you are well-leveled then battles of attrition shouldn’t be happening in the first place. That is also what Elixirs are for. Save them for critical situations!
There’s not much for me to say about the Devout simply because it is such an important job . Rather than tell you why you should have a Devout, I should be wondering why you don't have a Devout. How do you survive anything?
For those comparing the Devout to the Sage, the Devout has much more MP to throw around.
