Tips

 * 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 spell immunity and it also overrides lifesteal.

Trivia

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