New Champion idea (Ava, the liberator)

Ava the liberator

She is a bipedal/humanoid bird who is a resident of the Kumungu Jungle, like nidalee and zyra, and is the last of her kind. She cannot speak but can communicate with others through thought. With that said, in game jokes, dances and such would not be vocalized by her (other than a squawk perhaps) but it would cause a reaction or statement from other champions nearby instead.

Passive: Molt; Ava has no mana or energy bar. Instead she gains stacks over time as she molts her old damaged feather for stronger ones. Each stack grants a small boost to armor and magic resist and slightly increases her health regeneration. When she dies she loses half of her stacks. Max 10 stacks. Her appearance will also change based on the number of stacks she has from dull colors to brighter colors. Abilities use up stacks and have additional effects if used at max stacks.

Q: Ava channels and becomes immobile for a short duration. During that time any directional based skills used by enemy champions will be cast in her direction. During this time she is immune to any form of cc but can still receive damage. At max stacks she is granted a shield proportional to her health. Costs 3 stacks.

W: Under my wings; upon first cast Ava dashes to a target direction. The first friendly champion she comes in to contact with is taken under her wing and is targetable. Upon the second cast she dashes to a target direction and the friendly champion is the released in front of her. The second cast can only happen is an allied champion is taken under her wing, otherwise it works like a single dash. At max stacks the dash distance is increased and she shields her ally after the dash is complete. Costs 1 stack per dash.

E: Stay away; Ava spreads her wings and causes a powerful gust that knocks any opponents back who are caught in it. She is knocked back a short distance in the opposite direction as well. Damage is proportionate to the number of stacks she has and her ability power. At max stacks the width and length of the knock back are increased. Costs 2 stacks.

R: Cleansing rain; Ava raises her staff in the air and summons a small cloud then slams her staff in to the ground causing it to rain around her. When the rain falls it cures stuns, taunts, fears, ect. When used at max stacks she also heals her allies proportional to her ability power. No cost but it would have a large cool down.

Let me know what you think! thanks

And if you haven't figured it out this idea is for a support champ
