So Im pretty new to this game but Ive been playing for a few days. Ive spent a lot of time customizing the character tactics for each member of my party. Im not really sure how that all works though. Do they still use other abilities that I have not assigned? I mostly set up when to use heath, when to defend my mage, and when to use certain abilities. But there are many abilities that I have not assigned. Do the characters use them on their own?
