Champion Idea! Please share, give opinions, and give thoughts!

I'd had an idea, and i'd like to see what you guys think of this! This is totally fictional, and not official at all. just my imagination!

Draxus, the Forsaken Knight Picture him as a knight in armor, with cracks and purple stuff coming from the cracks. He would wield a large one handed sword.

Draxus can be played as a squishier assassin similar to or , or a tankier bruiser, like or .

Passive - Battle Scars Draxus gains bonus damage everytime he is killed, and deals more damage to champions he has killed.

One death = +0.5 attack damage One kill against champ = +0.5 attack damage against them (similar to Garen “villain” passive) 5 kills against champ = +2.5 attack damage against them

Q - Dashing Slash Draxus dashes to target area. Draxus swings his sword when reaching target area, dealing damage. The dash CAN be interrupted, and will not swing his sword if he is stopped. Draxus’ next 3 basic attacks will deal bonus magic damage after dashing. Champions marked with Knights resolve will take bonus magic damage form the basic attacks. (Scales off of AD)

W - Knight’s Resolve Draxus focuses his energy for 3 seconds. (He can still move and activate abilities while focusing) Draxus can click W again to end the 3 seconds early. After these 3 seconds or if he reactivates it early, Draxus will deal damage in an area around him, and this will mark enemies with Knight’s Resolve. The damage dealt to enemies is based on the damage that Draxus recieves in the 3 seconds. (Maybe like, 15%) (scales off of AP)

E - Shattering Blow Draxus strikes the ground, causing spikes or blades to shoot out of the ground in a cone in front of him. (they stay in the ground by the way, they sort of eject out of the ground) These spikes deal medium damage and knock-up enemies in front of him. Enemies marked with Knights resolve will be stunned for a short time after being knocked up.
(Scales off of AD)

R - Cryptic Blade Draxus channels for 1 second. He then proceeds to throw his sword like a spear as a skillshot. The first champion hit is impaled, slowing their movement speed and causing enemies in a radius around them to take damage over time unless they leave the radius. Draxus can then proceed to reactivate his ultimate, to remove his sword and send it back to him. In doing so, it will deal AOE damage to enemies around the impaled target. While the sword is in his target, he will have his attack damage halved. The longer the sword is in his target however, the more damage the AOE attack will deal. Enemies marked with Knights resolve will take a small amount of bonus damage from all of these effects. (Scales off of AD, and the over time damage while target is impaled scales off of AP)

Again, this all fictional and none of it is official. If you think he is OP, tell me. If you think he is cool, tell me! Any opinions hate or love are appreciated. TY! <3
