Upon taking fatal damage, Sion briefly becomes invulnerable then enters a frenzy, restoring himself to full health but losing 1 (+ Sion's level) health per 0.25 seconds, increases by 0.7 (+ 0.7 x Sion's level) per subsequent tick. 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 using any learned ability.
STATIC COOLDOWN: 100
Active:Sion gains 50% bonus movement speed that decays over 1.5 seconds.
While in the Glory in Death state, Sion can move, attack and use item actives, but cannot use summoner spells or his normal champion abilities.
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 or receive a attack speed buff while in Glory in Death, Glory in Death will actually decrease his attack speed (attack speed will be 1.75).
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.
Glory in Death will still trigger if Sion is killed by the Nexus Obelisk.
First Cast:Sion channels, increasing the damage of Decimating Smash over the next 2 seconds and the range over the next 1 second. If the channel is interrupted, Decimating Smash will go on a reduced 2 second cooldown.
Second Cast:Sion deals physical damage to all enemies in the target area. If he has charged for less than 1 second, he will slow all enemies in the target area by 50% for 0.25 seconds. If Decimating Smash is charged for at least 1 second, Sion smashes his axe into the ground instead, knocking up all enemies hit for 1.25 seconds, up to 2.25 if Decimating Smash is fully channeled.
Decimating Smash will not grant sight of Sion to an enemy standing outside a brush he is in, similar to Nunu'sAbsolute Zero.
COST: 65 / 70 / 75 / 80 / 85 mana
COOLDOWN: 13 seconds after shield expires
Passive:Sion permanently gains 2 bonus health whenever he kills a unit, increased to 10 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)
Minions and monsters cannot be pushed through walls, even when the knockback would ordinarily leave them within passable terrain.
COST: 100 mana
COOLDOWN: 140 / 100 / 60
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 turning speed is significantly slower than normal.
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.
While Unstoppable Onslaught is active, Sion's movement speed is hard capped at 950. As a consequence of this, building movement speed items will only cause him to gain ground over the initial acceleration and does not grant a significant increase in total distance travelled.
If Sion has a movement speed over 950 when he casts Unstoppable Onslaught, he will actually suffer a decreased movement speed.
