I have seen a lot of people who think that companions just magically level without doing anything... So I started asking them what they do when they log in... They invoke... lol the first 3 times per day give you and your companion exp.. I think it is 3.... anyway, more than once.
Companions get EXP from most things that you do. This includes collecting leadership tasks and Invocation. Watch the companion EXP bar the next time you invoke. This is where the magic exp comes from that you are seeing.
Would be nice to have a polling feature in the forums. Seem to be a lot of posts on this problem. If they could all be put into one, we would know how wide spread this problem is. Then maybe they would fix it.... For now, I'm off to play FF14 till they fix this. I can't play something that crashes every few minutes.
