Ebril, The Tortured Soul

This is my first character idea of a mage/ support let me know what you think and any suggestions.

Lore: Thresh killed a young boys' mother and took the boys' soul. This boy, named Ivan, was tortured and alone over the years of being captured. One moon rising on the Shadow Isle, Ivan heard singing off in a distance of a familiar voice, so using all his life force he left the cage that held him, but bound to the chains used to keep him tied to the mortal world this spirit is wonders to find the voice who sung that night. Ivan joined the league under the name Ebril in hopes to find his purpose, the voice and of coming back to life. So he takes the souls of others and devours them hoping to bring him back to the mortal body he once conceived.

Passive: Kills on champions grant 10 spirits, assists grant 5, last hits grant 1. Spirits can be collected and used to heal himself with his ultimate. Spirits give health/ap/mana i do not know yet based on how much he has.

Q: Spirit Bomb, AOE skill shot. Ebril throws a super charged spirit dealing damage. Spirit Shot, fast moving Skill shot. Ebril launches a super charged spirit dealing damage around the target hit.

W: Chained Escape, Ebril leaves behind his cloak and is able to launch himself towards allies or enemies like yasuo. Has set distance from cloak. Devouring Chain, Ebril launches one of his chains towards an ally or enemy connecting himself to them. he may reactivate to pull himself to chained target. Has set distance.

E: Screech, Ebril screams scaring away all enemies from him, small aoe. Attracting Taste, Ebril sucks in all enemies to him, small aoe.

R: Unstable Hunger, Ebril consumes as many spirits needed to reach max health and spreads the rest in an area around him. Spirits automatically go towards Ebril when health is lost. Turning in into frenzied state Stable Spirit, Ebril now absorbs the spirits of enemies around him and loose spirits near him. returning him back to normal state.
