[Champion Concept]Azelat, the High Seraphim (or anything else)

I'll start with a note: this concept is about the champion fantasy and mechanics, not about the champion overall. I imagine him as a seraphim with his own animations because I find it cool, but he can be anything else. So I'll omit the lore, it's not important.

So, I imagine this champion as another member of Kayle and Morgana's race, armed with a spear, I think it goes very well with his mechanics, I'll talk about them soon.

Ok, the important things: He's a magic damage bruiser, specifically of the diver type (Riot made such distinction with the Juggernaut update), so I guess the most similar champion is Diana. He has an insane amount of mobility, BUT it's all delayed or highly telegraphed. When I came up with this concept I realized that it was very similar to Sion, but while Sion has the slow big cc and big burst, this concept has actually the feature on the mobility. The most important thing is that I wanted to create something unique, something that does not still exist in LoL. I wanted to create a champion which uses a hit-and-run tactic to fight, but more than other champions. He is on the extreme end of the spectrum with "extreme mobility, extreme counterplay". Now, it may seem counter-intuitive or maybe op, but let's explain the kit:

Passive - High flight Azelat stores charges of High flight every X seconds (scales with level?) up to a maximum of Y(scales with level?). Every time Azelat uses a basic skill, he can cast High flight within 2 seconds (using the same button, the actual skill goes in cd normally). Using High flight, Azelat can blink to the target position in a decent range (something like 700-1000 units, but it can be changed, obviously) after a 0.8 seconds delay. I explain better: I imagine this skill like Pantheon ult or Spider Elise E(animation wise): Azelat opens the wings and rapidly rises to the sky, vanishing, than immediately lands in the target position (this could be shown to allies and/or enemies). It takes half the time to rise (so 0,4 seconds) and half to land (0,4 seconds). This skill does not make him untargetable, because he instantly start to land after he goes off screen.

Q - Holy dive This is probably the skill I like the most in the entire kit. Passive - All enemy champions get the debuff Holy target. Damaging a champion with an auto attack or a skill consumes the debuff, dealing extra magic damage and slowing by 99% for 0,1 seconds. Getting at least 500 units of distance between you and a champion resets the debuff. Active - Azelat dashes in a target direction (like 600 units). After he collides with a unit, or after he covers max distance, he immediately dashes back to starting position. They are considered two different dashes, so normal stuns and snares will make him stop in the arrival point of the "current" dash. He deals magic damage in small area around the "switch dash" position and slight knockback (much like Gragas E).

W - Angel fall An edited version of Pantheon Skyfall. First cast: after a short cast time, Azelat rises up to the sky and becomes untargetable for up to 1,5 seconds. On the target position, a circle expands gradually over the duration (visible by everyone, it has a minimum and a maximum width). Second cast: anytime during the 1,5 seconds or after it passes Azelat descends and strikes with force the ground, dealing magic damage in (which increases over the charge time) in the area (the circle). If at least 0,75 seconds had passed, the enemies hit are also knocked up. I know, I know, this is Sion Q. Well, actually I created this champion before Sion rework. I couldn't remove a skill just for this. XD

E - Majestic blizzard This can look a bit complicated. Azelat performs 3 to 6 dashes (depending on skill level) "drawing" a triangle (or a square, a pentagon, an hexagon). The time it takes to "draw" depends on the dimension of the area (you choose it by simply pointing the skill when you use it; it has a minimum distance) so it's the quickest when you use it a the minimum (but then you'll barely cover a cho gath standing in front of you), and it's the slowest at maximum (covering almost 2/3 of a lane width), taking from 0,2 seconds to up to 1 second. After every dash he leaves a silhouette of himself which has a one-auto-hit life. Anyway, like Q, every dash is separate from the others. After this time or after the skill is interrupted, Azelat creates a Dot area which deals magic damge and slows that lasts for up to 10 seconds. If all the remaining silhouettes are destroyed, the area vanishes.

R - Seraphim might Azelat empowers himself for a short time. For 10 seconds, Azelat cannot use his passive, but all his basic skills have no cooldown, inflict half damage and cost half mana.

And that's all. I think the playstyle is pretty much self-explanatory, but if you have questions, well, I'll answer. Too much op? Too much shitty? Remember, everything can be changed, what I want to sell is just the fantasy I wanted to deliver with this concept.
