Sion is League of Legends’ undead juggernaut - a tank who doesn’t fully stop fighting even after being reduced to zero health, which makes him one of the most disruptive frontline threats to face when he’s ahead. His slow, telegraphed abilities hit hard enough that opponents can’t afford to ignore him even when they see them coming.
Role and class
Sion is a top-lane (and occasionally jungle) tank who deals surprising amounts of damage for a champion built to soak up punishment. He’s designed to be the first one into a fight, using his health pool and unique death mechanic to absorb pressure that would kill most other tanks outright.
Core kit overview
Sion’s defining trait is his passive: when he’s reduced to zero health, rather than dying immediately, he enters an undead state for a few seconds where he can still move and attack, dealing bonus damage before finally dropping - a mechanic that lets him land a game-changing final blow even after “dying.” His main engage tool is a channelled charge that gets stronger the longer he holds it, knocking up and damaging everyone in its path once released - a slow but devastating way to start a fight from range. He also has an ability that shields him and deals damage to nearby enemies, useful for trading in lane, and a passive-and-active combo that lets him cleave through minion waves quickly. His ultimate is a long-range charge that grants him increasing movement speed the longer it channels, letting him close huge distances to join a fight already in progress.
Strengths and weaknesses
Sion’s biggest strength is the threat of his charge-up abilities - both his engage and his ultimate can catch an entire team off guard from a surprising distance, and his death passive means even a “successful” kill on him can backfire on the enemy. He’s also an efficient wave-clearer for a tank, letting him keep lane pressure without falling behind on farm.
His main weakness is predictability - his charge-up abilities have an obvious wind-up that experienced opponents can simply walk away from or interrupt with crowd control before it goes off. He also has limited mobility outside of those channelled abilities, making him vulnerable to being kited once his engage tools are used.
How he’s typically played
Sion is played primarily in the top lane, farming safely with his wave-clear before looking for charge-up engages on isolated targets or as a teamfight starter once his team groups up. His long-range ultimate makes him a strong pick for joining fights happening elsewhere on the map.
Common matchups and synergies
Against opponents without reliable crowd control to interrupt his charge, Sion can land engages consistently and control a fight from the front. Against champions who can stun or silence him mid-channel, his engage becomes much less reliable. He pairs well with teammates who can follow up immediately on his knock-up, since the crowd control window from a landed charge is a strong setup for burst damage from allies.
