I feel like an idiot for having to ask this, I have changed classes many many times before and never had this problem. I went and did all the quest to get to LL. Found the vendor that sells the beginner weapons for the classes. Purchased the lvl 1 book weathered grimoire. Then I go to equip it to change my class and it wont give me the option. If I manually move it to the weapon slot i get a error that says "unable to equip, you have not yet unlocked that class." Am I missing something here? is there a quest or something?
