Yorick Rework

Randomly though of this on my spare time he really needs a rework i feel this would work well however needs significant balancing before release if so.

Yorick: The Gravedigger

Primary Role : Fighter Secondary Role : Mage

Passive : Unholy Covenant Yorick and his ghouls apply stacks of Unholy Covenant to enemies with their basic attacks. Each stack increases the damage of yorick and his ghouls by 3% capping at 16% or 5 stacks (Ghouls do not trigger on hit affects but they gain 15% of Yorick's attack speed and all ghouls last 8.5 seconds, Enemy champions lose one stack of yorick's passive every 5 seconds).

Q : Omen of War [Range : 750(Skillshot)] [Cost : 55/65/70/85/125 mana] [Cooldown : 13/10/9/8/7] Yorick launches a Spectral Ghoul forward in a strait line if the ghoul hits an enemy champion it deals 100/165/170/185/240 plus 15% of attack damage as physical damage if the enemy has 5 stacks of Unholy Covenant this will deal true damage. (This Ghoul will then act as normal dealing 10/15/20/25/45 plus 5% attack damage per basic attack.

W: Omen of Pestilence [Range : 250] [Cost : 20,25/30,35/40,45/50,45/60,55 mana and health] [Cooldown : 7/6/5/4/3] Yorick deals 150/170/190/200/260 plus 25% of ability power and slows the target. If this ability kills the target it spawns a Decaying Ghoul this unit deals 15/40/50/80/100 magic damage per second to all units around it and slows them by 20% at all ranks, its basic attacks deal 5/8/10/15/25 plus 15% ability power as magic damage(The Decaying Ghoul will lock on to the nearest enemy champion after spawning).

E: Omen of Famine [Range : 100] [Cost : 55/65/70/85/90 mana][Cooldown: 14/12/11/10/9] Active : Yorick's next basic attack will deal only 65% damage but will heal him for 8% of his maximum health a Ravenous Ghoul then spawns on the target the ghoul deals 5/10/15/20/25 damage and heals Yorick for 1.5 % of his missing health per basic attack.(this effect is not treated as lifesteal)

R: Omen of Death [Range : 800] [Cost : 100/150/200 mana] [Cooldown : 140/100/90 seconds] Self Cast : Yorick conjures a controllable revenant of himself this revenant has 70% of his attack damage. If he dies while the revenant is active it will sacrifice itself to revive him for 15 seconds. Ally Cast : Yorick conjures a controllable revenant of a targeted ally this revenant has 20% bonus movement speed and has 55/60/70% of their attack damage. If they die while the revenant is active it will sacrifice itself to revive them for 10 seconds. Ghoul Cast : Yorick spawns an Ethereal Ghoul this ghoul has 35% bonus movement speed and taunts the first enemy it attacks for 2.5 seconds, this will reduce the cooldown of this ability by 50% and refund 50 mana the Ethereal Ghoul deals 10 magic damage and 10 physical damage per basic attack (Does not scale) and deals 50% bonus damage to champions below 15% health

This Rework should also feature the following :

-Increasing the size of hitboxes and animations for Yorick's ghouls -New updated ability icons and splash art -Easter eggs -New Skin -Bugfixes
