Sion, the Undead Juggernaut is a champion in League of Legends [1].


Glory in Death
Glory in Death

Upon taking fatal damage, Sion briefly becomes invulnerable then enters a frenzy, restoring himself to full health but begins to drain a percentage of his maximum health per second, draining faster the longer he is alive. Sion can freely move and attack during this time, gaining 100% lifesteal, attacking at 1.75 attack speed and dealing 10% of his target's maximum health as on-hit physical damage (capped at 75 bonus damage against monsters).

Additionally, Sion gains the ability to cast Death Surge.png Death Surge using any learned ability.

Death Surge
Death Surge

Active: Sion gains 50% bonus movement speed that decays over 1.5 seconds.

Ability Details
Glory in Death is a self-buff ability, which triggers upon Sion's death.
Death Surge is a self-buff ability.

Additional Information:

  • Sion can cast item actives during "Glory in Death".
  • The attack speed granted by Glory in Death isn't additive with Sion's base attack speed: it sets his attack speed to a static number. If Sion's standard attack speed exceeds 1.75 attacks per second, Glory in Death will actually decrease his attack speed.
  • Sion's death timer will begin to tick down when he is first killed, not when Glory in Death's reanimation expires.
  • The cooldown of Death Surge is refreshed upon triggering Glory in Death, meaning it is always available to cast at least once. Realistically, it is unlikely that a reanimated Sion will survive to cast Death Surge more than once.
  • Sion cannot use summoner spells while in the Glory in Death state.
  • Glory in Death will still trigger if Sion is killed by the Nexus Obelisk.
  • Glory in Death occupies a low priority for effects that trigger upon death: it will always trigger after effects such as Guardian Angel item.png Guardian Angel's or YorickSquare.png Yorick's Omen of Death.png Omen of Death.
  • MordekaiserSquare.png Mordekaiser's Children of the Grave.png Children of the Grave will spawn its ghost only if Sion dies in both normal state and Glory in Death state while under its effect.
Decimating Smash
COST: 50 / 55 / 60 / 65 / 70 mana
COOLDOWN: 10 / 9 / 8 / 7 / 6
Decimating Smash

First Cast: Sion starts channeling, increasing the damage of Decimating Smash over the next 2 seconds. If Sion's channel is interrupted by crowd control, Decimating Smash will have a reduced cooldown.

Second Cast: Sion smashes his axe into the ground, dealing physical damage in an area in front of himself and briefly slowing enemies hit. If he charges Decimating Smash for at least 1 second, enemies hit will be knocked up for 1.25 seconds, up to 2.25 if Decimating Smash is fully channeled. If Sion casts Decimating Smash before 1 second, he will slow whomever he hits instead. Minions take 60% damage.

  • Minimum Physical Damage: 20 / 40 / 60 / 80 / 100 (+ 60% AD)
  • Maximum Physical Damage: 60 / 120 / 180 / 240 / 300 (+ 180% AD)

Soul Furnace

Passive: Sion permanently gains 2 bonus health whenever he kills a unit, increased to 8 against large units and champion kills and assists.

Active: Sion surrounds himself with a shield that absorbs damage for up to 6 seconds. After 2 seconds, Soul Furnace can be recast to detonate the shield if it hasn't been destroyed, dealing magic damage to all nearby enemies. Bonus damage from the target's maximum health is capped at 400 against minions and monsters. The shield will detonate automatically if it persists for the full 6 seconds.

  • Shield Strength: 30 / 55 / 80 / 105 / 130 (+ 40% AP) (+ 10% of maximum health)
  • Magic Damage: 40 / 65 / 90 / 115 / 140 (+ 40% AP) (+ 10 / 11 / 12 / 13 / 14% of target's maximum health)

Additional Information:

  • The health bonus can be triggered by killing an enemy unit with any of Sion's damage sources, including autoattacks, champion abilities, summoner spells and item actives.
  • Both the initial cast and shield detonation have no cast time and do not interrupt Sion's previous orders.
Roar of the Slayer
COST: 25 mana
COOLDOWN: 12 / 11 / 10 / 9 / 8
Roar of the Slayer

Active: Sion bellows in the target direction, dealing magic damage to the first enemy he hits, as well as slowing it and reducing its armor by 20% for 2.5 seconds.

  • Magic Damage: 70 / 105 / 140 / 175 / 210 (+ 40% AP)
  • Slow: 40 / 45 / 50 / 55 / 60%

If the target is not a champion, it will be knocked back X units - dealing 150% damage to all enemies it passes through and slowing them by the same amount for 2.5 seconds. Minions and monsters cannot be knocked through terrain.

  • Increased Damage: 105 / 157.5 / 210 / 262.5 / 315 (+ 60% AP)

Unstoppable Onslaught
COST: 100 mana
COOLDOWN: 140 / 100 / 60
Unstoppable Onslaught

First Cast: Sion bellows, which can be heard by all players, and begins charging in the target direction for up to 8 seconds, during which time he cannot cast abilities nor attack, but is immune to all crowd control effects. Sion's trajectory will update toward the mouse cursor over the duration, but his rotation speed is significantly slow.

If Sion collides with an enemy champion or terrain, charges for the full 8 seconds, or recasts the ability, he will slam the ground with earth-shattering force, dealing physical damage and slowing surrounding enemies. Enemies hit directly are also knocked up and then stunned for a short duration. The damage and crowd control duration increase over the first few seconds of the charge, capping at 200% damage and 1.75 seconds respectively.

  • Minimum Physical Damage: 150 / 300 / 450 (+ 40% bonus AD)
  • Maximum Physical Damage: 300 / 600 / 900 (+ 80% bonus AD)

Colliding with terrain will cause Sion to stun himself for a short duration.
