Sion combos

The Undead Juggernaut

3 Sion combos explained key by key: in which order to cast the abilities, when to use them and what each step does. The main combo is Q › E › AA. Further down: every ability's cooldown, cost and range, and the skill max order measured over ranked games.

Sion combos

The stun

Q › E › AA AA

When: An enemy is within range.

A Decimating Smash charged long enough knocks up and stuns; Roar of the Slayer damages, slows and reduces armor.

The engage ultimate

R › Q › W

When: An enemy is far away.

Unstoppable Onslaught charges while accelerating and you can slightly change your path; the impact knocks up based on the distance traveled.

The shield

W › AA AA › W

When: You are engaged.

Soul Furnace surrounds you with a shield; recast it after 3 seconds to deal magic damage to nearby enemies.

Common mistakes

• Releasing Decimating Smash too early: it only knocks up after a long enough charge.
• Casting the ultimate with no direction: it accelerates and does not stop.
• Forgetting your passive: you come back temporarily to life.

Cooldowns, costs and ranges

A combo only comes back once its abilities are off cooldown: these values (rank 1 to max rank, in seconds) tell how long to wait between two combos. Source: Data Dragon 16.19.1.

Official ability descriptions

PassiveGlory in Death

After being killed, Sion will temporarily reanimate with rapidly decaying Health. His attacks become very rapid, heal him, and deal bonus damage based on his target's maximum Health.

QDecimating Smash

Sion charges a powerful swing in an area in front of himself that will deal damage to enemies when released. If he charges for enough time, enemies hit by the swing will also be knocked up and stunned.

WSoul Furnace

Sion shields himself and can reactivate after 3 seconds to deal Magic Damage to enemies nearby. When Sion kills enemies, he passively gains maximum Health.

ERoar of the Slayer

Sion fires a short range shockwave that damages and slows and reduces the Armor of the first enemy hit. If the shockwave hits a minion or monster, it will be knocked back, damaging, slowing, and reducing the Armor of all enemies that it passes through.

RUnstoppable Onslaught

Sion charges in a direction, ramping up speed over time. He can steer his charge slightly with the mouse cursor location. When he collides with an enemy he deals damage and knocks them up based on the distance he has charged.

Riot's official tips for playing Sion

• You only have very slight turning ability during Unstoppable Onslaught, so make sure to use it in straight paths.
• Roar of the Slayer is a great setup ability to land a very powerful Decimating Smash.
• The Soul Furnace buff displays how much shield strength is remaining, use this information to time its explosion perfectly.

How to play around Sion's combos

• Even if Sion still hits a Decimating Smash, making him release the charge earlier reduces its impact.
• Use the time after Sion has died to reposition and prepare for his return.
