Feel No Pain

Sion has a 40% chance to reduce incoming physical attack damage by 30/40/50 at levels 1/7/13.

Current League

Glory 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.

Coming from current LeagueSecond life, charged Q and global charge all belong to the modern kit, not this one.

AP Sion must pre-arm Death's Caress, walk into 550 range and protect the shield long enough to detonate; Enrage and Cannibalism are separate auto-attack tools rather than extra AP burst.

Remembering Sion in 2013Q and W both carry +90% AP ratios (an AP-burst build) while E and R are pure attack-damage/lifesteal, and Enrage's health cost per attack fights against the AP build's lack of sustain.

The two builds pull in opposite directions.

History & Notes

Released 2009-02-21, one of the original forty champions. Classic ships the pre-rework kit, frozen at patch 3.13.24. The modern game plays a different champion, compared under “Vs. modern”. Riot's next 3 balance steps after the freeze are listed below.

Changed after 3.13

  1. V4.5
    • Stats, Armor increased to 21.75 from 17.75.
  2. V4.18
    • Full Relaunch, Title changed to the Undead Juggernaut from the Undead Champion
    • Full Relaunch, Complete visual upgrade across all skins.
    • Full Relaunch, Sion turns berserk once he loses all his health, gaining a full life bar along with significant attack damage, attack speed, and lifesteal as he bleeds out. His abilities are all replaced by Death Surge, which gives him a huge but brief movement speed boost. Sion dies once his health drains out.
    • Full Relaunch, Sion plants his feet, rooting himself as he winds up and swings his axe in a broad area before him. Decimating Smash deals increasing damage the longer it's charged, and once it's at least half-charged, knocks up all caught enemies when unleashed.
    • Full Relaunch, Passive: Sion earns bonus max health every time he kills a unit.
    • Full Relaunch, Active: Sion creates a bloody shield around him. If the shield stays intact for its duration, it explodes, dealing magic damage to all nearby enemies. Sion can also detonate the shield early by 20px|link= reactivating the ability.
  3. V4.19
    • Stats, Health per level increased to 73 from 70.
    • Glory in Death, Health decay changed to 2;4;6;8;10;12;14;16;18;20;22;24;26;28;30;32;34;36 from 0.5% maximum health.
    • Glory in Death, Per-tick health decay changed to 1.4;2.8;4.2;5.6;7;8.4;9.8;11.2;12.6;14;15.4;16.8;18.2;19.6;21;22.4;23.8;25.2 from 0.4% maximum health.
    • Glory in Death, Bug Fix: Sunfire Cape's Immolate now persists past his original death.
    • Decimating Smash, Mana cost reduced to 45/50/55/60/65 from 50/55/60/65/70.
    • Decimating Smash, Bug Fix: Some crowd control effects not reducing cooldown to 2 seconds when they interrupt charge-up.
