Trevoke - the corrupted light

Note: I originally thought this charterer to be female. Also, i did not include the values for this champion as this was just a concept

This chamion idea comes off the idea of Nocturne. Trevoke has dedicated his eternal body to killing Nocturne in revenge for his brother. Overall, Trevoke is a justice oriented champion, like Garen, but he is twisted by the very evil he hunts. Trevoke uses light to destroy any who prevent him from achieving his goal. Trevoke is meant to be a solo protector/assassin. I picture this champion being a jungle/top laner.

Passive (Revenge): Trevoke links with an alied champion at the start of the game. He can only link with 1 champion per game. If this ally champion takes damage when Trevoke is within a certain range, he becomes engulfed in hate and deals more damage to the enemy champion. If the allied champion is killed within a small amount of time, Trevoke still deals the increased damage, as before, but now also ignores a percentage of the enemies armor for a short amount of time.

Q(Light's Darkness): Note: Trevoke does not have weapons, so the projectiles he shoots out come from his arms. I imagine it looking like a drgon ball z: kame kame ha

This is a skill shot ability in which Trevoke throws a projectile at a target area. Like twisted fate, there are two colors above his head when he activates this ability. One is a white ball(white), and the other is a dark ball(black). If he throws the projectile when he has a white ball above his head: any enemy hit will be rooted for a short period of time. This ball is smaller than the dark ball, so its hit box is smaller. Can only root 1 enemy If he throws the projectile when he has a dark ball above his head: any enemy hit will be slowed for a short duration. This projectile is bigger so its hit box is going to be bigger. This can apply to multiple targets

W(Crying Light): Trevoke becomes angry at the memory of his dying brother in his arms and shoots darkness from his arms dealing damage. If the target if infected with Light's Darkness(Q), Trevoke's next auto attack ignores a % of the enemies armor

E(Evolved Darkness): #1 Trevoke teleports(jumps?) to a target area knocking back enemies a short distance. I pictured this acting like a Gragas ult but with Trevoke as the projectile. This ability does not do damage. This ability is up for change as i feel it might make his kit too strong and too much cc. Below is an alternative

E(Evolved Darkness): #2 Trevoke jumps onto an enemy champion and fills their body with darkness. This deals % health damage

R(Light Brings Death): Trevoke can swap places with any allied champion within range and stuns all champions within range. This is not a global ult so he must be in range. I know this might be used as a "troll" ult, but I feel it really goes along with his lore and his kit as a jungler.

I understand that some of his abilities might need some tweaking but I look forward to see if this champion concept is given a chance. Thanks for reading ^_^
