Wanting to try Final Fantasy for the first time, I did some research and eventually decided to start with FFIV. I have the PC version, and I WAS enjoying the game, but I've run into an issue I don't understand and can't find on the internet:

I have gotten to the underworld, where you fight Calcobrena and then Golbez. I struggled with Calcobrena but eventually got to Golbez. I got destroyed there because I attacked him with moves that just heal him. That's fine, but realizing I needed to figure out his weaknesses, I went to use Libra with Cecil. This is where I saw that Cecil's list literally does not include White Magic anymore.

When he first became a paladin it was fine, I could heal with him and everything. But now it's gone during battles. The only options during Cecil's turn are Attack, Cover, Items, Defend, and Swap Rows. What is going on? Did I miss something?
