Immun, the Dark Aberration

So, this is an idea, created by a friend, but he is to shy to post it himself (although he does want it posted).

Champion idea: Immun, the Dark Aberration

Passive: Mutant Abomination Immun's basic attacks and abilities deal an additional 10/130/250(+15% AD)magic damage over 4 seconds. Enemies that die under the damage over time drop Mutated Blood, which can be picked up by anyone, enemy or ally. If an ally picks it up, they get a buff called Helpful Mutation, which gives them +0.2% base HP and Mana regen, +0.5% AD and AP, +0.1 Armor and MR per stack. If an enemy picks it up, they get a debuff called Harmful Mutation, which gives them -0.2% base HP and Mana regen, -0.5% AD and AP, -0.1 Armor and MR per stack. The buff/debuff stacks indefinitely and lasts 20 seconds and can be refreshed if you pick up another Mutated Blood.

Q: Vile Claw Range: 550 Cost: 5% max HP Cooldown: 16/14/12/10/8 Immun dashes forward, dealing 40/80/130/190/260(+40% AD) physical damage to minions until he hits a champion or reaches the end of his path. When he hits an enemy champion, he stuns them for 0.5 seconds, dealing 20/40/65/95/130(+20% AD) physical damage, flips over them and then proceeds to slash them twice for 85/110/135/160/190(+45% AD) physical damage each, applying one stack of Mutation per slash. Second part of Vile Claw also applies on-hit effects. Vile Claw also deals 15% bonus physical damage to targets below 50% HP.

W: Volatile Pustules Range: 350-radius Cost: 30/35/40/45/50% max HP Cooldown: 25 Immun channels for 2.5 seconds, then explodes, dealing 200/275/350/425/500(+35% AP) magic damage to all enemies around him, applying 2 stacks of Mutation to every champion in the blast radius. While channeling, Immun recieves 25% more damage (excluding true damage). After finishing the cannel, Immun is stunned for 2/1.75/1.5/1.25/1 seconds (tenacity does not lower the stun duration).

E: Thirst for Blood Cost: 5% current HP Cooldown: 14/13.5/13/12.5/12 Passively, Immun gains 5/10/15/20/25% bonus AD and 5/7.5/10/12.5/15% bonus movement speed. When activated, Immun gains double AD and movement speed bonus for 5 seconds and deals 10/25/40/55/70(+5% AD) bonus true damage to enemies below 50% HP. While on cooldown, only movement speed bonus is lost.

R: Ultimate Evolution Range: 500-radius Cooldown: 100/80/60 Immun absorbs all Mutated Blood in a radius around him, healing himself for 1/1.5/2% max HP per stack absorbed and dealing 100/150/200(+15% AP +20% AD) magic damage to all enemies and applying 1 stack of Mutation to all champions around him. For the next 7 seconds, Immun's abilities are disabled, but his autoattacks deal 400% AD in a 120-radius cone, split equally amongst enemies hit. When ultimate goes on cooldown, all Mutation stacks are lost.

Alternate skin: Ballerino Immun

Description: Immun is a small, crooked man with red mutation bloats on his neck, his left eye and a few on his arms and legs. He has sharp claws and fangs, one of which is sticking through the right side of his mouth. His skin is grey and dirty. He has very little hair on the right side of his head, grey colour with a white highlight over his right eye (red colour). He has a short reptilian tail with spikes. He wears torn brown pants with a rope instead of a belt. He thinks he is a perfect creature because his mind got corrupted by dark pools he slept in for decades. He also talks about himself in plural. His voice is high pitched and raspy. He also dislikes light and colours, having lived in darkness for decades. He emphasises on the sentances being true or false, repeating 'yes, yes' or 'no, no' multiple times.

Lore: Magic is a powerful sort of energy. People could control the elements, the weather and even time itself. But nobody has ever been able to recreate life with it. In a world, far away from Runeterra, Ry'han flesh-shapers created a perfect creature. The creature was named Primus, for it was the first succesful attempt at flesh-shaping magic. Primus was the king's ultimate killing machine, killing mercilessly and swiftly. But after many years a man came to rid the lands of the wicked king and his army. Primus fought with all his might, but in the end he fell down, mortally wounded. The wicked king somehow survived the onslaught and tossed Primus into the flesh-shaping laboratory. The laboratory was dark and cold, just like the king's heart. Primus walked in endless circles around the laboratory until he stepped in something warm. He thought it would heat his body up so he wouldn't die. He was wrong. Food was no problem for Primus. Whenever he felt hungry, he just broke a glass chamber containing a failed experiment and slowly ate it. If he felt thirsty he would drink the flowing blood. After his meal he would go back to the warm pool. He survived for decades, until a tall, dark man opened the doors into the laboratory. Primus had grown into a terrifying monstrosity, ugly and disgusting, that he named him Immun, which means Foul in his language. Having lived in those dark pools for too long, Immun was a threat to be reckoned with. So the dark man teleported himself and Immun to the institute of war, where the summoners could try to fix the poor creature's corrupted mind, body and soul. In the institute of war Immun grew tired of waiting and asked the summoners for permission to fight in the Fields of Justice. Immun now hunts unsuspecting champions, feasting on dead creatures and hides in the shadows. He should never have been created. From his creation onward, flesh-shaping magic is forbidden. Only a few still dare to break this rule. And if they do, Immun already lurks behind them, waiting to pounce.
