[Champion Concept] Blatar, the Disciple of the Sky (No Artwork)
Passive: Eternal Movement
Blatar's power mirrors the power of the eternal movement of the sky and clouds. 15%/20%/25% of the damage Blatar deals to enemy champions is converted into bonus Movement Speed for 2 seconds. This bonus Movement Speed can be refreshed but it cannot stack unless Blatar consecutively basic attacks one target (example: Dealing a total of 500 damage against one target with consecutive basic attacks will grant Blatar 75/100/125 bonus Movement Speed).
Q: Lightning Dash (50/60/70/80/90 MP, 7 second CD at all ranks)
Blatar moves at the speed of lightning, teleporting a short distance and dealing 20/25/50/65/80 (+50% AP) magic damage to all units between his new location and previous location.
W: Weeping Sky (50/65/80/95/110 MP, 15/14.5/14/13.5/13 second CD)
Blatar casts rain upon a target area, dealing 20/30/40/50/60 (+15% AP) magic damage per second for 4 seconds. Enemy champions and large monsters that are caught in the rain receive a debuff for 5 seconds after leaving the rain. Blatar's next basic attack or ability against an enemy with the debuff will use the rainwater on the champion as a conductor, stunning them for 1.5 seconds. The stun duration increases by 0.5 seconds for every second the target spent in the rain. Targets cannot be stunned more than once in during only one duration of Weeping Sky (Can't perma-stun champions and monsters while they are standing under the rain).
E: Biting Wind (30/40/50/60/70 MP/second)
Blatar uses the essence of wind to empower his pole-arm, granting him 20%/25%/30%/35%/40% attack speed and giving him 10/20/30/40/50 magic damage on-hit.
R: Look Up (50/100/150 MP, 90/75/60 second CD)
Blatar hops onto a cloud, allowing him to walk through units, granting him bonus movement speed equal to the bonus damage percentage from Heavenly Swipe whenever it is activated, and negating displacement methods against him for 7.5/10/12.5 seconds. Additionally, while Blatar is on his cloud, every enemy unit he passes or flies over changes their direction to face him and marks enemy champions briefly. Blatar cannot use this effect on marked enemy champions.
Appearance: Black shaggy hair, blue eyes, light clothing with little armor (grey colour scheme), wields double headed pole-arm, 17 years old.

Lore: Blatar was born on the highest peak of Mount Targon and was part of a Targonian clan that worshiped the sky. At a young age, Blatar had shown to have very special regarding the weather of the mountain, such as being able to shape clouds into animals or objects whenever he commanded and calling on rain and wind. These powers were very similar to the founder of his clan: Tosaro. During Tosaro's time, the clan worshiped him as if he were the sky itself due to his immense power. When Tosaro eventually died from old age, he asked the clan to not worship him any longer and instead worship the sky and the Heavens as they are eternal and they will continue to live on. Blatar aspires to become greater than Tosaro and eventually more powerful than the sky itself so the entirety of Mount Targon will recognize and look up to him and have his existence eternal in the minds of all.
Let me know what you guys think or if you want to know more, this only my second time doing this, so any constructive criticism will be very appreciated, thanks :P
BIG EDIT: Changed the passive thanks to Onimarus and I also changed the W because it felt kind of weak to me.
