Champion idea: Ibarus, Soul of Eternal Death and Balance

Ibarus was a creature of death, fit to be born within the void. He was the first of a humanoid species, meant solely to balance out the world between the humans squabble over good and evil. Ibarus felt fit to ignore his fate and had no wish to deal with others. He often stayed alone, in a hut in Kaladoun, next to the Serpentine River. Later in his life a monster suddenly appeared out of the serpentine river. It had no head, just a long dark thin body. The creature also had no heart or other vital organs. Ibarus, knowing only how to slaughter weak creatures of Runeterra could only stand in awe at how the monster quickly flew toward him. Ibarus could almost hear fate laughing at him. The creature plunged itself into Ibarus's heart and he blacked out. When he woke up he felt a surge of dark energy flow through him. He suddenly understood that he could not defy fate forever. He laughed loudly at the sudden liking to killing his victims at will. The next day his luck ran out. King Jarvan IV suddenly came in person to scout the area were reported murders kept popping up everyday. Ibarus was caught with his scythe still in a Demacian guard. Jarvan IV cut up and obliterated Ibarus without a second thought. However, Ibarus could no longer be killed, for he bore the curse of the monster in the Serpentine River. He needed more experience with his extreme power if fate was to require him again. He heard news of the perfect place to do just that. Once Ibarus reformed into one piece, he immediately set off for the League of Legends.

-Passive, Rending Scythe/ Fatesworn: Criting only does 145% damage, but it gives Ibarus armor penetration that stacks up to 3 times. Falling below 10% health temporarily turns Ibarus untargetable, but Ibarus does 55% damage and loses movement speed.

-Q, Thanatos: Ibarus summons a judge of the dead temporarily that drags enemies towards itself and then explodes when a champion gets to close or the durration runs out. The unit can't be targeted and is immobile.

-W, My Position: Ibarus dashes forward and does small damage to the first enemy he collides with. Upon collision Ibarus blinks the unit struck to the location Ibarus was when he started the dash.

-E, Patience, Victim: Ibarus slams his scythe down in a small range in front of him after channeling. Enemies struck take heavy damage and are rooted for a short time.

-R, Prepare For Fate: Ibarus cancels all enemies channels and abilities in motion without any exceptions, and also stuns enemies caught, in an area around Ibarus. Ibarus can't move during this time, but allies walking over the zone get increased movement speed. This ability has a very high mana cost, and Ibarus can continue to hold down the button assigned to this ability to keep the ability out for a longer duration, but it costs even more mana.

Skin: Archlight Ibarus.
