Pierces spell immunity on the triggering enemy. Does not target spell immune secondary enemies.
Buff modifier_item_mjollnir_static: Dispellable with any dispel.


  • Successive casts on the same target do not stack, but refresh the duration.
  • The radius is centered around the shielded unit.
  • Upon proccing, the proccing unit and 4 random enemy units within the radius are hit.
    • If the damage source is more than 900 range away, then only the 4 random enemies within range will be hit.
  • Static Charge cannot proc more than once per second.
  • Despite the description, Static Charge can proc on any damage, including from spells, not only on attacks.
  • Does not trigger on self-inflicted damage, and damage flagged as HP Removal.

Chain Lightning
Grants a 30% chance on attack to release a bolt of electricity that leaps between 12 targets within a 650 radius, dealing 180 magical damage to each. Lightning proc pierces evasion.
Proc Chance: 30%
Bounce Distance: 650
Number of Bounces: 12
Bounce Interval: 0.25
Damage: 180
Cooldown: 0.2
Buff modifier_mjollnir_chain: Dispellable with death only.


  • When obtaining multiple items with the Chain Lightning ability, only the one that has been continuously the longest in the inventory works.
  • The lightning bounces in 0.25 second intervals, so hitting max targets takes 2.75 seconds.
  • Can proc on fogged or invisible units, but does not bounce toward fogged or invisible units.
  • Can never hit the same unit more than once per proc.
  • Against a lone target, adds an average of 54 magical damage to every attack.
  • Chain Lightning can proc while a previous chain lightning is still bouncing.
  • Chain Lightning does not proc if the attacker is dead. However, it can proc if the target is dead.
  • Attacks which proc Chain Lightning cannot miss.
  • The Mjollnir Chain buff is a hidden buff required for the lightning to jump.
  • Chain Lightning does not use a regular cooldown. It is neither displayed on the item icon when proccing, nor is it affected by cooldown manipulating effects.

Recommended Heroes[]

  • Heroes whose item build includes Mjollnir as a situational item:


  • Mjollnir is very effective against heroes with illusions like Naga Siren minimap icon.png Naga Siren, Spectre minimap icon.png Spectre and particularly Phantom Lancer minimap icon.png Phantom Lancer and Chaos Knight minimap icon.png Chaos Knight that can surround you because the lightning goes all around you compared to cleave and the Static Charge has more chance to be triggered.
  • This item is very good for pushing, you can apply the Static Charge on a creep to push a lane safely while you jungle and get extra gold.
  • This is the most effective item to push back mega creeps.


  • Mjölnir is the name of Thor's Hammer in Norse mythology.
  • Mjollnir's item icon used to have a little bit of animations. Random static electricity would appear on the hammer, which briefly illuminated the hammer in a blue light. This animation was removed in the [ Info Needed ] patch for unknown reasons.
