Since chocobos are going to be able to fight with us in 2.0 there was one thing that came to mind.

Casting spells is activated by voice, hence why when silenced, you can't cast.

Chocobos, however, do not talk in human. Does this mean that when they are hit with silence they are immune to it?

If immune to it, couldn't we learn chocobo to make ourselves immune to silence and always cast spells without the fear of silence?

Of course if they are silenced then that must mean silence is more than just something that makes your vocal cords go retarded.

What exactly is silence doing if it can mute a person, and animals?
