(Champion Concept) Zar'Kan The Beast Of The Void

Not the best concept out there but I thought that riot should release a bone-based champion, and what better place to house one of these than the void? My champion is an AD based bruiser that in simpler terms, "goes into a fight a tank and becomes a high burst fighter when it is prolonged." Below are the champion's abilities:

Passive: Release the Beast- Zar'kan rampages through the battlefield, reveling in the pain from fighting and his own bones piercing his skin. Every 5% of maximum hp Zar'Kan loses converts into the same amount as AD but is reduced back to normal when healed.

Q: Dread Claw- After two consecutive auto attacks, Zar'Kan may activate this ability, causing him to slash his target twice in a row, one slash doing bonus physical damage and the other doing bonus magical damage. Upon being hit by dread claw, the target is slowed briefly.

W: Compaction- Upon activation, Zar'Kan increases the density of his bone structure, reducing all incoming damage he takes for the next 5 seconds by 50%. However, after the duration Zar'Kan will take 20% of the unreduced damage he took as recoil

E: Skewer- Zar'Kan punches the ground and extends his bones into the ground. After a short duration, the bone will shoot out of the ground at a target location, impaling a target and rooting them for 2 seconds dealing physical damage.

R: No Escape- Zar'Kan reaches back, ripping his spine out and lashing it in a target location. As he does so, Zar'Kan also extends all of the bones from his body to great lengths, Impaling all of those hit by his spikes. Afterwards, Zar'Kan retracts the bones and pulls all enemy champions either impaled by his spikes or hit by his spine towards him.

Basically, Zar'Kan is a bruiser built for a tank meta. The champion is very reliant on health stats as well as tank stats for both sustain as a ccing tank and so his damage will spike harder in a teamfight. The champion is capable of going head on into a teamfight and duking it out will impaling his targets. But Zar'Kan's biggest talent is his ultimate. Think of it as an Oriana ultimate except that instead of pulling everybody towards the ball, they all get pulled into you. Basically flash into the enemy team and ult to bring them to you and boom, the enemy team is piled up into one area for your team to clean up the mess. Zar'Kan's weakest point would most likely be during the early game, due to his passive. In order for Zar'Kan to deal damage, he requires a lot of health. This way his max hp becomes higher increasing the amount of AD he receives for every 5% of his maximum HP that he loses. His w also helps him with his passive. Not only does it make him tankier for a brief duration, but it does cut his hp down a decent amount depending on how much damage you have taken, making this a double edged sword. Basically, you take damage to deal damage.

Now to close out the concept, here is some lore:

"Zar'kan is a monster from the void unlike any other. A beast by every means of the word, Zar'Kan is a hulking behemoth and a mindless killing machine. Granted with a unique ability to alter it's bone structure, the monster is able to rush into a battle without second though, impaling and skewering it's victims and leaving the carrion for the lowly scavengers. Even though it is a senseless beast, there is a dread thought when watching it move, that what it does is calculated and thought through, and that the monster harbors a sinister conscious deep within..."
