Prior to the creation of the League of Legends, the city-states of Demacia and Noxus were locked in a brutal series of on-again-off-again wars that spanned the course of centuries. Both powers sought an advantage over the other, but Noxus was the city-state willing to forego conventional morality to achieve its goals. Only brute strength and the will to use it mattered to Noxus, and this is best exemplified in the murderous warrior, Sion.
Used by the Noxians as a human battering ram, Sion would be sent thundering ahead of Noxian troops. He would mercilessly slaughter foes with his large double-bladed axe, 'Chopper'. His complete disregard for caution ultimately cost him his life, as he was captured and summarily executed by Demacian forces.
The Demacians thought that the beheading of Sion would be the end of his bloodthirsty ways. Death, however, was merely the beginning of Sion's rise to power. The famed Noxian assassin, Katarina, recovered Sion's remains and Noxian necromancers reanimated the behemoth to serve Noxus once again. Sion's reanimation actually bestowed new powers on him and increased the potency of his existing abilities, making him even more of a terror to behold on the battlefield.
The Noxian High Command had a powerful new weapon in their hands - one they have brought to bear as a champion in the League of Legends. Even though Sion's increased powers would make him a powerful tool for the High Command's use outside Fields of Justice, Noxus no longer risks losing one of their greatest champions in the League to chance or circumstance. Sion's days as a front-line fighter for Noxus' military conquests are at an end.
Feel No Pain
Sion has a 40% chance to take up to 30 / 40 / 50 reduced damage from basic attacks.
Sion turns berserk once he loses all his health, gaining a full life bar along with significant attack damage, attack speed, and lifesteal as he bleeds out. His abilities are all replaced by Death Surge, which gives him a huge but brief movement speed boost. Sion dies once his health drains out.
Sion plants his feet, rooting himself as he winds up and swings his axe in a broad area before him. Decimating Smash deals increasing damage the longer it's charged, and once it's at least half-charged, knocks up all caught enemies when unleashed.
Passive: Sion earns bonus max health every time he kills a unit.
Active: Sion creates a bloody shield around him. If the shield stays intact for its duration, it explodes, dealing magic damage to all nearby enemies. Sion can also detonate the shield early by reactivating the ability.
Sion bellows in a target direction, damaging, slowing, and shredding the armor of the first enemy struck. If Roar of the Slayer hits an enemy minion or jungle monster, Sion's scream also knocks them back a significant distance. The thrown minion or monster then damages and slows all other enemy units hit.
Sion starts charging in a target direction, building up speed as he moves and trampling enemy minions along his path. He can cancel his charge early, at which point he slams the ground, dealing area of effect damage to all nearby enemies. Otherwise, Sion charges an extremely long distance, only stopping once he hits an enemy champion, wall, or reaches the end of his charge. If Sion charges into an enemy champion, he knocks them up and deals area of effect damage; if he hits a wall, Sion stuns himself briefly and deals area of effect damage around him.
