Has anyone actually used a Phial of Fantasia yet?

[Kyriea]

I used mine earlier, I'm pretty sure you can change everything except name birthday and deity unfortunately. I was spamming through it cause it was when the 3102 error hit so had to try over and over to get it to work, but I remember the bottom 3 options were greyed out so you were unable to change them. Hope this helps a little bit, sorry I can't say for sure I only used mine to change a couple of options and never really thought about birthday etc.

Edit just to add - I think it's available on all characters when you create them so you could always create a new character just to check what is able to be changed before you use it on your main. Saves wasting it if you can't actually change what you need.
