So i've completed the main story line( to the credits) and I have little idea of where to go or what to do next other than lvl up my other classes/jobs.

I don't know where to find the quests to unlock things like the coil or Shiva. I don't know where to get the best gear for my main class.(Warrior) I don't know to get to the other Primals or the best way to get tomes/seals for stuff either.

i'm also kind of at a loss on the best way to lvl my other classes too, so i thought i would turn here for help!

i've not been playing that long so I'm still rather new to this.
