Character Concept- Fearl- The Elemental God

Hi, this is my character concept. I would love some feedback on how can i Improve. ^_^

Passive- Godly power- Every time Fearl hits an enemy or Monster, he gains additional MS. He also gains 5% atk dmg for each 20% health he's missing. (MS-20/30/50) Lets start with Ult- Unmatcahble Wit- Passively, 25% of the damage dealt by Fearl is magic damage. Every 6th auto, he deals true dmg based on his max hp%. Actively- U channel for 1.5 sec, an enormous fireball full of all the elements shoots out, sweeping the lane and dealing damage along the way. (DMG- 200/350/550) (0.9/1.1/1.5 AD/AP) units hit between reduce the damage by up to 40% damage reduced.

Q- Fire lord- Fearl throws a fireball in a target direction. 3 subsequent hits on an enemy deal 2% max hp dmg over 3 sec. Applies on hit effects. (DMG- 70/100/130/170/220) (0.8 AD) Cooldown- 14/12/10/8/7 W- Water bound- Fearl stuns an enemy champion for 2 sec and deals extra damage to the target for the next 5 sec. (DMG- 60/75/100/125/170) (0.7 AD) CD- 18/16/14/13/12) E- The "Unmissable"- Fearl uses his powers to create an AoE zone that heals nearby allied champions while doing damage to enemy champions. (HEAL/DMG- 200 (0.1/0.25/0.3/0.4/0.5 AD))
