Ariss, the Crystal's Arrogance.
Melee.
Passive: Vanity. Whenever Ariss casts an ability, she leaves a crystal lens where she was standing. There can be up to three lenses on the field at any time, and a see through mirror image of Ariss is projected through every lens within a certain range.
Q: Polish. Ariss strikes an enemy, coating them with a reflective substance. Does half damage. Polished enemies take full damage from all of Ariss's abilities. 6/5.5/5/4.5/4
W: Reflect. Ariss looks upon a crystal lens, and takes the place of the image on the other side. 9/8/7/6/5
E: Present. Ariss draws light to herself and expels it, dealing damage to all enemies within a radius. Any crystal lenses within a certain range also emit a line nuke that deals half damage to any enemies struck. 7/6.5/6/5.5/5
R: Pursue. Deals 1% of the ability's damage to every enemy champion on the map, creating a mirror image that grants sight next to any polished enemies. She can reactivate pursue to switch places with the mirror image. 120/90/60
Basically, I think this would be a champion which would be extremely pretty to watch.
