^^ I need help on developing my Cra, I don't know what she should be.
so advice would be much appreciated...

I don't recommend Agi, it's a long hard road, and it pisses me off sometimes.
So you're down to Str, Int, or Crit.
Str has huge dmg potential with spells and bows.
Int has slightly less power, but can hit many people at once with Burning and Explosive later on.
Crit has Daggers, and Punitive Arrow to toy around with. Punitive, on a crit, deals 1-100, so with proper str. equips you can easily top 200 like everyone else.
But I'm no Cra expert, Sacrier's are my thing. Good Luck.

Strength Cras' are incredibly powerful, however, are very hard and you don't get amazing spells until later levels.

Intelligance Cras' are awesome, and have a decently large arsenal of spells to fiddle with, namely spells such as Explosive (Or was is Destructive?) Arrow. You can down a large mob in a couple turns with that spell.

EDIT: Moved to Help Me! section

can you help me lvl her Zodi??

Sure xP But you should definately quest to level 11 and max something first. ^^

she's lvl 8 and i haven't maxed anything yet, i want her to be perfect, i messed up all my other chars i don't want to mess her up.

Will she be Int or Strength?

I haven't decided yet, I don't know which one would be the best for her.
I was thinking str but int is pretty powerful too.
