So I was following this page here from 2013 http://www.ffxivguild.com/ff14-black...-skills-guide/

I got my Thaumaturge to 30, archer to 15 and arcanist to 4

Did the black mage starter quest and am now set as black mage and have my soul crystal equipped, however I cannot see a way to use any cross class skills, mainly Physick is what i'm looking for. I cannot progress further in the black mage quests till i'm lvl 35 so think i've done everything I can.

Has something changed since all these guides were written?
