  • 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.
  • Does not trigger on the damage from Heartstopper Aura, Dispersion, Poison Sting, Corrosive Skin, Fatal Bonds.
  • Fully ignores HP removal and self afflicted damage.
  • 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.
  • Does not bounce on invisible units or units in the Fog of War.
  • Can never hit the same unit twice per proc.
  • All bounces together can deal up to 1200 damage (before reductions).
  • Mjollnir has an internal cooldown of 0.2 seconds

The bounces are 8 and not 4 like that of Maelstrom.
Static charge range is also 900

I found this works for meepo because you can put the static shield on your leading meepo and use him as a tank(preferably not your main meepo because he can hit from other sides while the shielded unit is targeted.

Great item for Sniper, because Headshot

And yes, it works with Helm of the Dominator (as others orbs) but when it procs, overwrite the other orb effect.
