Sion – Detailed Ability Guide (ARAM: Mayhem)

Sion in Mayhem is a lane-control monster who transitions into an unkillable raid boss or a disruptive zombie. You are not here to outplay people with mechanics. You exist to charge abilities in their face, absorb ridiculous amounts of damage, and force the enemy to overcommit kills that just bring you back for more. Every ability demands respect for its windup, but if you land them, the payoff is massive.

Passive – Glory in Death

Function: When Sion dies, he reanimates with rapidly decaying health. During this state, he gains attack speed, moves faster, and every attack slams the ground for bonus damage. He can also cast a short-ranged dash to knock up enemies.

Mayhem Use: In Mayhem, death is a tactical resource, not a failure. The mode’s high damage means you will die, but your passive turns that death into a seven-second window to punish the enemy team. Because fights are constant, you often revive right in the middle of a scrum, forcing enemies to choose between running or dying to a zombie.

Targeting and Hit Logic: You automatically attack the nearest target, but you can right-click to switch. Your dash has a short cooldown and hits the first enemy in its path. Use it to close gaps on squishies who think they are safe after killing you.

Combo Role: This is your "fail-safe." If you engage and get burst down, your passive lets you finish the job. It turns a bad trade into a potential double kill.

Early Fight Use: Early on, enemies often underestimate the zombie damage. If you die under their tower or during a close skirmish, just chase them down. They usually lack the mobility to escape.

Teamfight Use: In big fights, try to die in the middle of their backline. Your death zone disrupts their positioning and forces carries to kite backward instead of attacking your living teammates.

Counterplay: Smart enemies will kite you or use crowd control. Slows and stuns ruin your zombie chase. If they have strong disengage, your passive becomes a sad walk into nothing.

Leveling Priority: Does not apply.

Punishment for Wasting It: You cannot "waste" the passive, but you can waste the opportunity. Dying far from the fight or chasing an unkillable tank means your zombie contributes zero pressure.

Q – Decimating Smash

Function: Sion charges a massive overhead axe slam. The longer you charge, the more damage it deals and the longer the knock-up duration. It can be released early for reduced effect or fully charged for maximum devastation.

Mayhem Use: This is your primary threat tool. In Mayhem, the threat of a fully charged Q often does more work than the ability itself. Enemies have to respect the windup. You use it to zone, to peel, or to start fights when combined with your other CC.

Targeting and Hit Logic: It hits a large area in front of you. The hitbox is generous, but the windup is telegraphed. You need to predict where enemies will be, not where they are.

Combo Role: The classic combo is E (slow/knockback) into Q. The slow makes landing the full charge much easier. You can also flash during the charge to surprise people.

Early Fight Use: Early on, use short-charge Qs to last-hit minions and poke. Do not always go for the full charge; a quick tap still hurts and disrupts.

Teamfight Use: In teamfights, you rarely get a full charge off on mobile targets. Use it to zone enemies away from your carries or to follow up on a teammate’s CC. If an ally stuns the enemy frontline, charge up and hit the backline.

Counterplay: Any dash, blink, or interrupt stops you. Mobile champions can walk out easily. If you whiff a full charge, you are a sitting duck for several seconds.

Leveling Priority: Max this first for the damage reduction and cooldown lowering. You need Q up often to control space.

Punishment for Wasting It: Charging in plain sight with no setup is a free invite for the enemy to dump damage on you. If you cancel it or miss, you lose all lane pressure until it comes back.

W – Soul Furnace

Function: Sion gains a shield. After a delay, he can reactivate it to explode, dealing magic damage around him. Killing units permanently increases his maximum health.

Mayhem Use: This is your sustain and scaling engine. Mayhem’s constant minion waves mean you can stack health faster than on Summoner’s Rift. The shield helps you survive burst, which is critical in a mode where everyone deals too much damage.

Targeting and Hit Logic: The explosion is point-blank area of effect. It only damages enemies near you. You need to be in their face for it to matter.

Combo Role: Pop W before you go in. It absorbs the initial burst. If enemies focus you, let it explode. If they ignore you, you get free damage.

Early Fight Use: Use it to absorb poke. Last-hit minions with the explosion active to double-dip on wave clear and health stacking. Every wave is a chance to get tankier.

Teamfight Use: Activate it as you engage. The shield buys you time to charge Q or survive the initial focus fire. The explosion is often just a bonus, but it can finish low-HP targets.

Counterplay: The shield is not invulnerability. High-damage enemies can pop it before you detonate. If they break it, you get no explosion and no damage.

Leveling Priority: Max this second. You need the stronger shield and lower cooldown to survive mid-game burst.

Punishment for Wasting It: Popping W too early means it decays before you take damage. Popping it too late means you die before it helps. Timing is everything.

E – Roar of the Foe

Function: Sion fires a short-range shockwave that slows and knocks back a target. If the shockwave hits a minion, it knocks that minion much further, dealing increased damage and stunning the first enemy champion hit.

Mayhem Use: This is your setup tool. The minion-yeet is your most reliable way to start a fight or catch someone off guard. In Mayhem, where minions are always present, you almost always have ammunition.

Targeting and Hit Logic: You can target champions directly for a weak slow, or target a minion behind them to launch it. The launched minion travels fast and stuns on impact.

Combo Role: E into Q is your bread and butter. The slow or stun from E makes landing a charged Q almost guaranteed. You can also use E to push enemies into your tower or away from your allies.

Early Fight Use: Use minion projectiles to poke. They have long range and good damage. If an enemy steps near a minion, fire immediately.

Teamfight Use: Look for angles to fire minions into the enemy backline. If you cannot engage, use E to peel divers off your carries. The knockback creates space.

Counterplay: Enemies can dodge the minion projectile. It is a skill shot. If you miss, you lose your main engage tool for several seconds.

Leveling Priority: Max this last. One point is enough for the utility. The damage is nice, but Q and W are more important for your core game plan.

Punishment for Wasting It: Using E on a champion directly when a minion was available is a wasted opportunity. You lose the stun, the range, and the pressure.

R – Unstoppable Onslaught

Function: Sion charges forward in a direction, accelerating over time. He steers with slight adjustments. Upon hitting an enemy champion or reaching maximum distance, he slams the ground, knocking up and damaging everyone nearby. The ability can be cancelled early for a smaller impact.

Mayhem Use: This is your nuclear option. You turn into a projectile that cannot be stopped by crowd control. In Mayhem, the map is a single lane, so your R is almost always relevant. You can engage from your tower to their tower in seconds.

Targeting and Hit Logic: You pick a direction and commit. You can steer slightly, but you cannot turn sharply. The hitbox at the end is large, and the knock-up duration scales with distance traveled.

Combo Role: R is your primary engage. You slam into their team, knock them up, then immediately charge Q while they are recovering. Follow with W for shield and E for cleanup.

Early Fight Use: At level 6, look for a long-range R when enemies are overextended. The surprise factor is huge. Even if you do not kill, you force them back.

Teamfight Use: Use R to start fights or to counter-engage. If the enemy dives your team, turn around and R back into them. You can also use it to peel by knocking up divers. The unstoppable nature means you can run through their frontline to hit the backline.

Counterplay: You cannot be stopped, but you can be dodged. Mobile champions can sidestep at the last second. If you miss, you end up deep in their territory with no abilities, which is a death sentence.

Leveling Priority: Put points in at 6, 11, and 16. The cooldown reduction is vital for keeping up with Mayhem’s fast pace.

Punishment for Wasting It: A missed R leaves you out of position and useless for a long time. Charging R when your team is not ready to follow up means you die alone. Always check your team’s position before you commit.
