Hello everyone!

1st of all, its been a while since my last post here on forums, I started playing again in december 2014 after a 9 months break...

Im at ilvl 112 atm and blm is my main job, wearing some ironwork accs, armor and demon gear from WoD.

Atm Im doing my 2nd book and Im wondering if it is really worth the time to finish a zodiac weapon, if you compare it to the coil/ironwork weapons...

Nowdays I have around 3 hours a day to play ffxiv, cuz of my classes and work, so Im divided if I should continue with this quest or just leave it as it is...

How much exactly it will cost me?
Do I have to lvl a craft job in the late weapon lvls?
I read that theres a chance to fail to add materia into the weapon at a certain stage of the quest, how bad is the fail rate and how exactly it works? Can I add weaker materias and update them later when I have more gil?

Thank you very much for stopping by to read my post!
