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


Static Charge
Ability Affects Damage
Target Ally Units Magical
Places a charged shield on a target unit which has a 20% chance to release a bolt of lightning at an attacker and 4 nearby enemies.
Duration: 15
Cast Range: 600
Proc Chance: 20%
Damage: 200
Radius: 900
Cooldown 35 Mana 50
Partially blocked by Spell Immunity. Can be placed on magic immune allied units. Lightning will not strike magic immune enemies.


  • Strikes up to five enemies.
  • Strikes enemies within radius of the shielded unit, not the attacker.
  • Cannot trigger more than once per second.
  • Has no effect if cast on a unit that already has a Static Charge active on it.
  • Also triggered by damage-over-time abilities, but not by Heartstopper Aura icon.png Heartstopper Aura or Poison Sting icon.png Poison Sting.

Chain Lightning
Ability Affects Damage
Passive Enemies Magical
When attacking, there is a 25% chance that lightning will strike the target and 7 other nearby enemies.
Chance: 25%
Damage: 150
Bounce Range: 900
Blocked by Spell Immunity. The chain lightning effect from Mjollnir or Maelstrom will work, but will not damage any Heroes that are magic immune.
Unique Attack Modifier. Mjollnir is a Unique Attack Modifier that stacks with other Unique Attack Modifiers, but overrides them when Chain Lightning occurs.


  • Mjollnir is very effective against heroes with illusions like Naga Siren, Spectre and particularly Phantom Lancer. 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.

Recommended heroes[edit]


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

  • Recipe cost increased from 600 to 900.
  • Static Charge duration decreased from 20 to 15.

  • Static Shock area of effect is now centered around the unit with the Static Charge, rather than around the attacker.
  • Fixed Chain Lightning not functioning properly when it procs while a previous proc is still bouncing.
    • This affects Maelstrom and Mjollnir and makes them more reliable when they proc in sequence.


  • Changed the area type that is used when Static Charge hit units
