  • Mjollnir is very effective against heroes with illusions like Naga Siren minimap icon Naga Siren, Spectre minimap icon Spectre and particularly Phantom Lancer minimap icon Phantom Lancer and Chaos Knight minimap icon Chaos Knight that can surround you because the lightning goes all around you compared to cleave and the Mjollnir icon Static Charge has more chance to be triggered.
  • This item is very good for pushing, you can apply the Mjollnir icon 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.
  • The VFX of Mjollnir's Static Charge is an arc of lightning in the shape of a triquetra, a symbol that is sometimes seen in some of Mjollnir's real-life depictions.
  • 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 for unknown reasons.
