Sion is strongest when he gets time to charge heavy crowd control, creates a long-range ultimate engage, and forces opponents to waste damage into his huge health pool. Counter him by interrupting charged casts, sidestepping predictable engage lines, and attacking the damage dealers behind him instead of tunneling into the tank.
Quick Counter
Best counter type: Charge interruption, lateral dodging, anti-health damage, and backline access
Biggest danger: A fully charged knock-up or long-range ultimate starting a fight before your team is positioned
Best defensive response: Move laterally out of charge lines and save displacement or control to interrupt his telegraphed casts
Best punish window: After Decimating Smash or Unstoppable Onslaught misses
Fight plan: Dodge the telegraphed engage, avoid wasting everything on Sion first, then pressure the carries while his control is unavailable.
What Sion wants
Enemies grouped in front of a charged Decimating Smash.
Long lanes for Unstoppable Onslaught.
Opponents who spend all damage killing him before touching his backline.
Extended fights where his health pool and disruption absorb enormous attention.
How to beat Sion
Respect the charging animation and leave the impact area early. The spell becomes far stronger if you wait until the final moment to move.
Use interrupts or displacement when available rather than simply tanking a full charge.
Against his ultimate, move perpendicular to the path instead of retreating directly along the lane.
If Sion has already used his major control, look past him toward the enemy damage dealers unless he is the only safe target.
Best counter tools
Percent-health or sustained damage against very high health pools.
Displacement and interrupts for charged crowd control.
Mobility that sidesteps his ultimate path.
Backline access that prevents Sion from absorbing all attention.
Power spikes
Early: His charged crowd control is already threatening if opponents stand still in front of him.
Mid: Ultimate engage and growing health make him a strong fight starter and damage sponge.
Late: He becomes extremely durable, making target selection and anti-health damage more important than raw focus fire.
Key abilities to track
Decimating Smash: The charge is highly telegraphed and grows much more dangerous with time. Early movement or interruption prevents the strongest version.
Unstoppable Onslaught: The engage travels along a committed line. Lateral movement and terrain awareness are more effective than simply running away in the same direction.
Best items into Sion
Divine Sunderer: A strong option for compatible champions who want repeated percent-health pressure into Sion’s large health pool.
Liandry’s Torment: Useful for suitable magic damage champions who can repeatedly apply damage into high-health frontliners.
Blade of the Ruined King: A practical anti-health option for attack-based champions who can safely hit him repeatedly.
Common mistakes
Waiting too long before leaving a charged smash area.
Running directly away from his ultimate line.
Using every cooldown on Sion while enemy carries free-hit.
Building no answer to an enormous health stack when your champion can use one.
Fight them in this order
1. Spread and identify Sion’s likely engage lane.
2. Dodge or interrupt the charged control.
3. After the engage misses, move past him toward higher-value targets where possible.
4. Use sustained anti-health damage if Sion must be killed front-to-back.
