Fly

Enables you to fly over dense objects that are not densed roofs. Demons, Kais, and a few other races are born with the ability to fly and can teach others how to do it. This also applies to ranks, but otherwise you will learn it when you have enough energy to do so automatically.

Flying also gives you energy, but the initial is very draining and has to be mastered in order for it to be nearly drainless.
