A warhammer with the power of the storm. The Forge Lords of Brimstone created these weapons with a blessing from the storm god Tempest. The hammer head crackles with electricity, ready to release a thunder strike or call lightning from above.
Weapon (warhammer), very rare (requires attunement)
You have a +2 bonus to attack and damage rolls made with this magic weapon.
Thunder Strike. Once per turn, you can add the power of thunder to a successful hit with the hammer. The target must make a Constitution saving throw. On a failed save, a creature takes an additional 1d8 thunder damage and is pushed 10 feet away from you. On a successful save, the creature takes half as much thunder damage and isn’t pushed.
Lightning Storm. While you are holding the Storm Hammer, you can use an action to cast the Call Lightning spell at third level (save DC 15) from the weapon. This action can’t be used again until the next dawn.
Proficiency with a warhammer allows you to add your proficiency bonus to the attack roll for any attack you make with it.
This Dungeons & Dragons magic item is a less powerful version of Mjolnir, the Norse god Thor’s mighty hammer. In Norse mythology, Mjolnir was forged by dwarves out of the metal Uruz (or Urth), which was created by the giants. The dwarves were then driven underground by the giants, who took over their kingdom. When the gods decided to punish the giants, they sent Loki to free the dwarves. However, Loki tricked them and instead freed the giants. As punishment, the gods gave the dwarves the task of forging weapons for the gods. Mjolnir was forged by the dwarf Brokkr, who gave it to Thor.
