Siren ghost support champion

still working on the drawing but when its done ill add it. She has 2 ghost flames around 1 hand that she attacks with and has flaming hair. Hovers off the ground like janna and syndra do. Her W creates an AOE mist/fog around her that she can move by walking around in it her and all allie champs are invisible however enemies can see the fog itself. last for 5seconds at max rank.its passive effect is an ora that increases allie health regen by 50% doubled when fog is active. her Q sends out a skill shot fire ball that slows in a small AOE on the first enemy hit. if combed inside her W it will stun for 3second and cancel her W however it puts it on half the cool down. W will have a pretty long cool down to begin with. The will be a taunt of some kind that also reduces enemy damage by 20% at max rank for 5seconds at all ranks. I don't know what is should look like yet, but if anyone has ideas. The R is the syrians call that is basically a wide cone like scream in front of her that deals magic damage and silences enemies for 2seconds. Her passive is she is given an increase base movement speed boost anytime she takes damage.
