Sion is a champion in League of Legends.[1]

Abilities

Edit

Glory in Death

Glory in Death.png

Innate: Upon taking Death.png fatal damage, Sion goes into Stasis icon.png stasis for 1.5 seconds, after which he Omen of Death.png reanimates and enters a frenzy, restoring himself to Health icon.png 100% maximum health but losing 2 − 19 (based on level) health every 0.264 seconds, increasing by「 70% of the base value 」「 1.4 − 13.3 (based on level) health 」per subsequent tick.

Sion can move and use basic attacks but cannot use summoner spells during this time, and attacks at a fixed Attack speed icon.png 1.75 attack speed, gains Life steal icon.png 100% bonus life steal, deals 10% of the target’s maximum health as bonus physical damage On-hit icon.png on-hit, capped at 75 against non-champions, and is Ghost.png ghosted.

While Glory in Death is active, Sion's Health regeneration icon.png health regeneration and Heal power icon.png healing (besides Life steal icon.png life steal) are reduced by 100% and all of his abilities are replaced with Death Surge Death Surge.

If Glory in Death does not end within 60 seconds, Sion dies instantly.

Edit

Death Surge

Death Surge.png

Active: Sion gains Movement speed icon.png 67% bonus movement speed(note) that decays over 2.376 seconds.

Once at least one ability has been learned, Death Surge can be cast using any ability key, even for the abilities that haven't been learned yet.

Notes
  • Glory in Death is currently the only targetable Omen of Death.png zombie state.
  • Upon Death, Sion will drop non-permanent status effects (buffs and debuffs) that do not inherently persist through death before transitioning into Glory in Death:
    • These effects include undisplayed statuses, for example the 'already stunned by this'-flag of Veigar's Veigar's Event Horizon Event Horizon or Viktor's Viktor's Gravity Field Gravity Field.
    • Some item passives do not persist through death and will be lost for the initial few seconds of Glory in Death.
    • An example for a debuff that does persist through death is Brand's Brand's Blaze Blaze.
  • Glory in Death will still trigger if Sion is killed by the Nexus Obelisk.png Nexus Obelisk.
  • Upon death, the current cooldowns of Sion's summoner spells summoner spells are increased to 4 seconds. Afterwards, he is still unable to use them until he respawns or after a lock-out effect (excluding Stun icon.png crowd control except Stasis icon.png stasis) unlocks them.
  • Chronoshift Chronoshift and Guardian Angel Guardian Angel will take priority over Glory in Death.
  • Sion's death timer starts ticking when he first Death.png dies and not when Glory in Death's duration ends.
    • If Sion lives longer than his death timer lasts for, he will not revive until Glory in Death has ended. When it has ended, he will revive instantly, which can result in some odd interactions and bugs at times.
  • Glory in Death does not trigger on clones of Sion, such as with Test of Spirit Test of Spirit.
  • Glory in Death's Playful.png untargetability from the Stasis icon.png stasis does not Bullet strikethrough.png destroy in-flight Projectile.png projectiles.
    • Projectiles created while Sion is in the zombie form will still travel to him even after he dies.
  • At the start of Glory in Death, Sion's Mana resource.png mana drops to 0, but his Mana regeneration icon.png mana regeneration will remain in effect.
  • During Glory in Death Sion:
  • Trying to cast item actives during the initial stasis will buffer their casts instead, unless Sion issues another command before being able to act again.
    • Exception: Quicksilver Sash item.png Quicksilver can be used during the stasis after death.
  • Sion's attack speed during Glory in Death is fixed at 1.75 and it's unaffected by attack speed bonuses and Cripple icon.png cripples for the duration.
    • Buffs that allow for the normal 2.5 attack speed cap to be surpassed, such as Lethal Tempo Lethal Tempo and Hail of Blades Hail of Blades, will also break the upper limit of the 1.75 cap, but not the lower one. This means that while these buffs are active, Sion can exceed 1.75 attack speed, but cannot fall below it.
    • After the effect ends, the attack speed cap will not revert to 1.75 but to 2.5. However Sion will still not be able to go below 1.75 attack speed.
  • Buffs from jungle monsters Sion gains during Glory in Death (Crest of Cinders Crest of Cinders, Crest of Insight Crest of Insight) will not be lost once the duration ends.
  • By surviving for the full duration of 60 seconds, Sion will have suffered 36.4k − 345.5k (based on level) in health costs.
  • After Glory in Death ends, the corpse of Sion will retain unit collision despite being dead on the ground.
  • Even though its visuals are present, Dark Harvest Dark Harvest can never be gained from Sion under the effect of Glory in Death.
  • The effect that heals Sion back to full health at the start of Glory in Death cannot be modified by Grievous Wounds icon.png healing reductions and does not count towards the 'Damage Healed' statistic at the end of game lobby.
  • Glory in Death's on-hit effect also applies against structures other than Turret icon.png turrets. (note)

Notes
  • Death Surge will grant the bonus movement speed after a brief delay.
    • The buff is intended to grant 75% decaying movement speed, but instead grants 67% movement speed decaying with -8% per stat update.
      • Precisely this leaves him at 0% − 0% (based on time passed) bonus movement speed.
  • Death Surge has a shared cooldown across each ability key, regardless of which key is used to activate it. Thus, activating Death Surge with any ability key will put the others on cooldown.
  • Death Surge's cooldown resets upon death.
  • Death Surge's cooldown is affected by Cooldown reduction icon.png ability haste and thus the ability is technically able to be used up to twice during a single instance of Glory in Death, but this isn't practical.
    • Death Surge is not affected by Ultimate Hunter Ultimate Hunter, even if cast from the ultimate ability slot.

Edit

Decimating Smash

Decimating Smash.png

Active: Sion Channeling icon.png charges for up to 2 seconds to increase Decimating Smash's Range icon.png range, Airborne icon.png knock up duration, Stun icon.png stun duration, and damage every 0.25 seconds, which has up to a maximum bonus for the base damage and up to a 200% bonus for the scaling damage. Decimating Smash can be recast at any time within its duration, and automatically does so if the charge completes without reactivation.

Max. Base Damage Increase:
133.33 / 150 / 166.67 / 183.33 / 200%
Minimum Damage:
30 / 50 / 70 / 90 / 110 (+ 45 / 52.5 / 60 / 67.5 / 75% AD)
Maximum Damage:
70 / 135 / 200 / 265 / 330 (+ 135 / 157.5 / 180 / 202.5 / 225% AD)

If the charge is Silence icon.png interrupted, Decimating Smash is put on a 2-second Cooldown reduction icon.png cooldown.

Recast: Sion flails his axe in the target direction, dealing physical damage to all enemies in the area and Slow icon.png slowing them by 50% for 0.25 seconds. Decimating Smash deals 150% damage against Monster icon.png monsters and 60% damage against Minion icon.png minions.

Minimum Monster Damage:
45 / 75 / 105 / 135 / 165 (+ 67.5 / 78.75 / 90 / 101.25 / 112.5% AD)
Maximum Monster Damage:
105 / 202.5 / 300 / 397.5 / 495 (+ 202.5 / 236.25 / 270 / 303.75 / 337.5% AD)
Minimum Minion Damage:
18 / 30 / 42 / 54 / 66 (+ 27 / 31.5 / 36 / 40.5 / 45% AD)
Maximum Minion Damage:
42 / 81 / 120 / 159 / 198 (+ 81 / 94.5 / 108 / 121.5 / 135% AD)

If Decimating Smash was charged for at least 1 second, Sion instead slams his axe down, Airborne icon.png knocking up all enemies within the area for 0.5 − 1 (based on channel time) seconds and Stun icon.png stunning them for 1.25 − 2.25 (based on channel time) seconds.

Info

For the target to be hit, their center needs to be inside the red or blue areas (based on charge time), and their edge must hit the yellow part of the cone. If their edge also hits the white part of the cone they will be excluded from being hit. Cone is at 16 degrees and starts 800 range behind Sion's center. White cone has a radius of 720, while yellow cone has a radius of 1550.

  • Sion himself remains Lockout icon 2.png locked out of all actions for 0.25 seconds when releasing Decimating Smash.
  • Unstoppable icon.png Displacement immunity will also resist the application of the Stun icon.png stun.
  • Since the Stun icon.png stun duration is longer than the Airborne icon.png airborne duration, and both start at the same time, Tenacity icon.png Tenacity is still fully effective against Decimating Smash up to a cap.
    • This virtual cap is 60%-55.5% Tenacity icon.png Tenacity based on channel time beyond 1 second. Every value below this cap will lower the CC duration with no diminished returns.
  • A flash of the axe and change in brightness of the indicator on the ground indicates when the 1 second time frame is reached.
  • The damage of Decimating Smash is calculated when it is released. Gaining AD or upgrading the ability during its channel will update the damage of the coming hit.
    • Even though the cooldown starts when the ability is released, it will not be changed by gaining or losing CDR, or upgrading the ability, during the cast time.
  • The indicator is visible to the enemy only if they Sight icon.png see Sion himself.
    • If the channel is released before 1 second, enemies may see a particle at the far end of the hitbox, if it itself isn't outside of their Sight icon.png vision.
    • If the channel is released after 1 second, the only remaining indication is the visual effects and audio that plays on any units the spell strikes (these play on-target), provided the enemy does have Sight icon.png vision on those.
  • Forced movement without a Stun icon.png stun component (or the stun being Remove Scurvy.png cleansed previously) will not stop Sion from starting or continuing to channel. Its direction will not change with Sion's travel, however the location will update with him.
    • The location of the indicator updates at the beginning of the ability, at 1 second and at release.
  • The indicator of the ability is slightly shorter at its front than the hitbox of the ability is for Original Sion Original Sion, Mecha Zero Sion Mecha Zero Sion and related skins and chromas, while on Worldbreaker Sion Worldbreaker Sion, the indicator is slightly thinner at the front than the hitbox is, instead.

    Soul Furnace

    Passive: Sion gains Health icon.png 4 bonus health whenever he kills an enemy, increased to 15 for large enemies and Damage rating.png takedowns against enemy Champion icon.png champions.

    Soul Furnace.png

    Active: Sion grants himself a Hybrid resistances icon.png shield, which lasts for up to 6 seconds. Soul Furnace can be recast after 3 seconds while the shield holds, and does so automatically at the end of its duration.

    Shield Strength:
    50 / 75 / 100 / 125 / 150 (+ 40% AP) (+ 8 / 9 / 10 / 11 / 12% maximum health)
    Soul Furnace 2.png

    Recast: Sion consumes Soul Furnace's shield to deal magic damage to all nearby enemies, capped at 400 against minions and monsters.

    Magic Damage:
    40 / 65 / 90 / 115 / 140 (+ 40% AP) (+ 10 / 11 / 12 / 13 / 14% of target's maximum health)

    Both of Soul Furnace's casts can be activated during Sion's other abilities, other than the release of Decimating Smash Decimating Smash.

    Info
    • A buff icon in the HUD will show the current shield strength, so that the player can better calculate the timing of the second cast.
      • The initial shown value does not interact with Heal and shield power icon.png shield strength modifiers. Whenever the shield takes damage, it updates to the proper current shield amount, however.
    • The initial cast counts as an ability activation for the purposes of on-cast effects such as Sheen item.png Spellblade and stacking Force Pulse Force Pulse.
      • Detonating the ability manually does not.
    • Gaining or losing AP or health, or ranking up the skill while the shield is active will not change its shield value but it will change the damage of the shield's detonation.
    • The cooldown of Soul Furnace begins once the shield is removed.
      • Gaining or losing Cooldown reduction icon.png ability haste between the first cast and breaking of the shield will affect the resuming cooldown accordingly.
    • Soul Furnace also automatically detonates if Sion is killed without the shield being destroyed, e.g. by dying to the Nexus Obelisk.png Nexus Obelisk, even if Sion could not have detonated it manually yet.
    • Soul Furnace's bonus health can be obtained by any of Sion's damage sources (basic attacks, abilities, summoner spells, item actives).
      • This does not include last hits transferred to Sion artificially, through effects such as Spoils of War Spoils of War.
      • If the gold efficiency of a Ruby Crystal Ruby Crystal is considered 100%, each last hit or Damage rating.png takedown after Soul Furnace has been learned can be considered worth an extra 10.6 Gold 10.6 or 40g Gold 40g.
    • Sion must learn Soul Furnace before he can stack up its passive.
    • Sion does not gain bonus health from units that enter Revival icon.png resurrection on-death.
    • Killing the following unit types grants Sion 15 bonus health:
    • Killing the following unit types grants Sion 4 bonus health:
    • Killing the following unit types grants Sion no bonus health:

    Map-Specific Differences
    Nexus Blitz icon.png Nexus Blitz differences edit
    • On-unit-kill bonus health doubled.

    Edit

    Roar of the Slayer

    Roar of the Slayer.png

    Active: Sion bellows in the target direction, dealing magic damage to the first enemy hit, Slow icon.png slowing them for 2.5 seconds, and Armor penetration icon.png reducing their armor by 20% for 4 seconds.

    Magic Damage:
    65 / 100 / 135 / 170 / 205 (+ 55% AP)
    Slow:
    40 / 45 / 50 / 55 / 60%

    If the target is a Minion icon.png minion or non-epic Monster icon.png monster, they are also Stun icon.png stunned for 0.75 seconds and Airborne icon.png knocked back in the same line for up to 1350 units away from Sion, applying Roar of the Slayer's effects to all enemies they pass through as well as briefly granting Sight icon.png sight of the area along their path.

    Info
    • Minions or monsters that are flung away are immune to minion damage and take their damage once they are stopped if they would die to Roar of the Slayer's damage, by either colliding with terrain, reaching the end of their trajectory, or having their displacement interrupted.
    • Unlike the intial single-target projectile, a thrown minion or monster is not blocked by Wind Wall Wind Wall or Unbreakable Unbreakable.
    • Gaining or losing AP, or upgrading the ability while its projectile is traveling will change its damage for every future hit. This applies to both the intial single-target projectile, as well as the minion-projectile.
    • Roar of the Slayer will cast from wherever Sion is at the end of the cast time.

    Edit

    Unstoppable Onslaught

    Unstoppable Onslaught.png

    Active: Sion becomes Cc-immune icon.png immune to crowd control and Ghost.png ghosted and, after a 0.066 seconds delay, Channeling icon.png charges forward in the direction of the cursor for up to 8 seconds, during which he is able to steer at a slow turn rate while automatically navigating his movement. Unstoppable Onslaught can be recast after 0.4 seconds during the channel.

    The charge uses Sion's movement speed at the time of cast and is unaffected by external sources for the duration, including movement speed caps, while also gaining Movement speed icon.png 40 bonus movement speed every 0.1 seconds, up to 950 total movement speed.

    Unstoppable Onslaught 2.png

    At the end of the charge's duration, Sion Bear Stance.png leaps forward 300-units, landing after 0.55 seconds and slamming the ground beneath him. Sion will stop upon colliding with an enemy champion or terrain during the charge, slamming instantly and ending Unstoppable Onslaught prematurely. Crashing into terrain will cause Sion to Stun icon.png stun himself for 0.5 seconds.

    Enemies struck by Sion's charge are dealt physical damage. The base damage increases by 0% − 166.67% (based on channel time) and the Attack damage icon.png bonus AD ratio increases by 0% − 100% (based on channel time).

    Minimum Physical Damage:
    150 / 300 / 450 (+ 40% bonus AD)
    Maximum Physical Damage:
    400 / 800 / 1200 (+ 80% bonus AD)

    Enemies, including Turret icon.png turrets, within the slam are dealt the same physical damage and are Slow icon.png slowed for 3 seconds, and those in close proximity of Sion are also Airborne icon.png knocked up for 0.75 − 1.75 (based on channel time) seconds and after a brief delay become Stun icon.png stunned for the same duration. If Sion collides with an enemy champion, all nearby enemies are additionally Airborne icon.png pulled towards him over 0.5 seconds and after a brief delay become Stun icon.png stunned for 0.25 − 1.75 (based on channel time) seconds, increased to 0.75 − 1.75 (based on channel time) if they were hit by the leap.

    Slow:
    40 / 45 / 50%

    Recast: Sion stops charging, causing him to leap forward and slam the ground beneath him as if Unstoppable Onslaught had reached the end of its duration.

     
       "Chaaaaaaaarge!"

    Info
    • When Sion casts Unstoppable Onslaught a global warning can be heard.
    • Unstoppable Onslaught does not apply the knock up nor stun to enemies from slamming on collision with terrain.
    • Unstoppable Onslaught does not Airborne icon.png knock up non-champions hit by the charge.(note)
    • Unstoppable Onslaught can be activated twice or held down and released on both normal cast and quick cast. There is no other difference between normal cast and quick cast for this ability, either.
    • The initial cast counts as an ability activation for the purposes of on-cast effects such as Sheen item.png Spellblade and stacking Force Pulse Force Pulse.
      • The recast does not.
    • An enemy can only be affected by Unstoppable Onslaught once every 1 second.
    • After reaching maximum damage and stun duration (at 3 seconds) Sion will transition from using his haste animation to his unique charging one.
      • Reaching the threshold on Mecha Zero Sion Mecha Zero Sion changes his particle effects instead, most notably the 'Boosters' behind the vehicle.
      • The turning angle is not based on time and can easily be seen in practice when a Sion charges in-place due to bugs.
    • Nami's Nami's Surging Tides Surging Tides is the only known effect that can affect Sion's movement speed during the charge and that can place him above the normal MS value. However, without further multipliers, surpassing the 950 movement speed cap will require Nami Nami to have over 2150 ability power.
    • Sion does not always crash with terrain immediately upon touching it, enabling the player to turn beyond his maximum turning angle.
      • Casting the ability at point blank of a terrain will most often automatically change the charge's direction.
      • This is not usually possible with player-generated terrain.
    • Unstoppable Onslaught cannot charge through but can leap over player-created terrain (i.e Crystallize Crystallize).
    • Sion loses the Cc-immune icon.png crowd control immunity after finishing the Bear Stance.png leap.
    • Sion is not immune to Stun icon.png crowd control applied by his allies during Unstoppable Onslaught. For example, a Blast Cone Blast Cone triggered by an ally will cause the Channeling icon.png channel to be Silence icon.png interrupted.
      • An allied Bard's Bard's Tempered Fate Tempered Fate will be resisted however.
        • If it hits Sion during the 0.05-second delay before he starts the channel, he will not resist the effect and will initiate the slam immediately while in Stasis icon.png stasis.
    • Sion is immune to the Realm of Death Realm of Death for 2 seconds after completing the slam after the channel ends.(note)
    • Unstoppable Onslaught cannot strike the same non-champion twice in less than 1 second.
    • 𝐏𝐄𝐍𝐃𝐈𝐍𝐆 𝐅𝐎𝐑 𝐓𝐄𝐒𝐓 The distance between Sion's center and the center of the ground slam scales slightly with movement speed. This is suspected because running into a wall within half a second of charge time after starting at multiple thousands of movement speed shows a considerable difference, however this could also be due to a bug.
    • 𝐏𝐄𝐍𝐃𝐈𝐍𝐆 𝐅𝐎𝐑 𝐓𝐄𝐒𝐓 The leap appears to always have the same speed regardless of Sion's, at roughly 750.
    • Moving the cursor onto HUD elements (e.g mini map / champion portraits) does not jeopardize the cast and steering of Unstoppable Onslaught. The targeting will act as if the ground was targeted below the display element.
    • Even though the cooldown of Unstoppable Onslaught starts at the end of the effect, gaining or losing ability haste, or upgrading the ability during the effect, will not change the resuming cooldown.
    • Remove Scurvy.png Removing the Airborne icon.png airborne before 0.5 seconds will not prevent the Stun icon.png stun from being applied.
    • Unstoppable icon.png Displacement immunity will also resist the application of the Stun icon.png stun.
    • The following table refers for interactions while Sion is Channeling icon.png channeling:
