Abilities[edit | edit source]

Static Charge
Ability Affects Damage
Target Ally Enemy Units Magical
Places a charged shield on a target unit which has a 20% chance to release a shocking bolt at a nearby attacker and 4 additional enemies.
Cast Range: 800
Proc Chance: 20%
Proc Cooldown: 1
Search Radius: 900
Max Number of Targets: 5
Damage: 200
Shield Duration: 15
Cooldown 35 Mana 50
Partially blocked by Spell Immunity. Can be cast on spell immune allied units. Lightnings trigger on spell immune units without damaging them. Cannot target spell immune secondary enemies.


  • Double clicking the item casts it on self.
  • Successive casts on the same allied unit have no effect, wasting the mana and cooldown. The buff is not refreshed.
  • The search radius is centered around the shielded unit. When it procs, the proccing unit and 4 random enemy units within the radius are hit.
  • Lightnings cannot trigger more than once per second.
  • Fully ignores HP removal and self-inflicted damage.

Chain Lightning
Ability Affects Damage
Passive Enemies Magical
Grants a chance on attack to release a Chain Lightning that hits 8 targets, dealing damage.
Proc Chance: 25%
Bounce Distance: 900
Number of Bounces: 8
Damage: 150
Partially blocked by Spell Immunity. Can proc on Spell immune enemies without damaging them. Does not jump towards spell immune enemies.
Unique Attack Modifier. Stacks with other attack modifiers, but overrides them when Chain Lightning occurs.


  • Each Mjollnir in the inventory has an independent chance to proc. If 2 or more proc on one attack, only one chain lightning is released.
  • The same applies to Maelstrom and Mjollnir in the same inventory. When both proc on the same hit, Mjollnir has priority.
  • The lightning bounces in 0.25 second intervals, so hitting 8 targets takes 1.75 seconds.
  • Can never hit the same unit twice per proc.
  • All bounces together can deal up to 1200 damage (before reductions).

Tips[edit | edit source]

  • Mjollnir is very effective against heroes with illusions like Naga Siren, Spectre and particularly Phantom Lancer and Chaos Knight that can surround you because the lightning goes all around you compared to cleave.
  • 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.
  • The item is situational since the Chain Lightning damage is blocked by magic immunity and it also overrides lifesteal.

Trivia[edit | edit source]

  • Mjölnir is the name of Thor's Hammer in Norse mythology.
