Mjollnir

The Mjollnir is an Item purchasable at the Main Shop, under Artifacts. However, it can only be completed with items from the Secret Shop.

Tips

 * Mjollnir is very effective against heroes with illusions like Naga Siren, Spectre and particularly Phantom Lancer because the lightning goes all around you compared to cleave. As a carry, you should consider building this item when playing against these heroes. Because this Unique Attack Modifier stacks with others, you can freely build it for heroes with their own Unique Attack Modifier like Viper.
 * Static Charge triggers on magical damage as well as on damage from physical attacks, so Mjollnir is very effective against heroes who deal damage over time with their spells. Can be useful against the illusions too, because they can trigger it.
 * 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.

Trivia

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