i just want to know what levels / job levels i should be at or around to be strong enough to beat the end.
please and thankyou
For levels, be around the mid to upper 50's. 60 or higher if you want to make it easy on yourself. For jobs, make sure to have a Sage or Devout with you to heal and revive fallen characters. A ninja with a lot of Shurikens (and placed in the back row) is a good idea too. Other then that, just use other jobs that have been the most help so far for you.
I mean just normal levels. It's it good idea to level up Job levels as much as you can though.
