Help with animation , two animations idle and fire same time

Hi all!
I want to play Idle and Attack animations (dragon fire ball) at the same time.
At that moment I can only play one of them. If I attack My hero ıdle gone just I can see dragon ball.
Also I need that dragon ball movement if I can get any help I will be glad for it. Thanks anyway.
