Skin Idea: Cosmic Nova Illaoi (Legendary)
So I was inspired by Cosmic Blade Yi's Q. And here is the concept
Cosmic Nova Illaoi:
Appearance: Blue skinned, with stars over her body (like Aurelion Sol), clothed in white and gold armor. She is holding a glass ball with a star in it. That ball has small constellations trailing behind it.
Passive: When she is near a wall, a constellation forms similar to the ones made by Yi Q. When she is not nearby, the constellation retracts to a single bright star.
Q: Illaoi's Star forms a constellation and brings it down on the opponent. (Makes cool star exploding noises)
W: Illaoi's Star star turns bluish white to gold and she brings the ball down on the enemy, Causing a small explosion.
E: Illaoi Extends her star towards the enemy and a constellation extends to strike an enemy, if it does, it pulls out a constellation IN THE SHAPE OF THE ENEMY CHAMPION to attack and deal damage to them.
R: Illaoi Leaps up and Smashes the glass ball the star is kept in, which turns Red, and a bright bluish white nova represents the AOE. While her ult is active, many constellations spawn and she strikes her opponents with a bare blood red star. While her ult is active, her auto animation and SFX are changed to look and sound like burning
Joke: Stars that are not in motion are not special, It is the stars that are in motion upon which you will wish for me to show mercy.
Taunt: I've seen dark stars that are brighter than you.
