Hi, I just started few days ago. I am currently lol 4 whoa lvl 30 Mage and lvl 30 neophyte ranger. I just got enough to summon a job card. Should I summon now? I lvl led Mage thinking that if I got it it would unlock the Mage slot job but guess I was wrong. If I summon do I have a chance of summoning Mage even though I locked apprentice? So confused.
