Champion idea

So after playing the game for a while, I've come up with a champion idea and I'm interested in what everyone thinks. I've got the general idea of the champ down. The champ will be based around mirrors/glass (As stupid as that sounds, think about it and look at Irelia, shes based around blades, and Singed is based around gases)and will be a mage/support.

(Pass) Bad luck: When the Champion dies, the killer is hit with a debuff that makes them take 40%-50% more damage.

(Q) True light: (A bit irrelevant) Aims a mirror to magnify the sun and fire a beam of damaging light.

(W) Puts enchanted mirrors on an ally, giving them armor and reflecting a percentage of the damage dealt to that Champion.

(E) -WIP- Any suggestions?

(Ulti) Mirror image: Surrounds an enemy in mirrors and snares them for 2.5s, once the snare has ended a copy of the same champion is created and is in control of the caster that deals 60% of the enemy Champions damage and has 75% of their health.

Some things might not be balanced and of course the (E) I haven't thought of yet. please leave your opinions and suggestions in the comments. (Moedakin: The Thousand Faced Man)
