Mjolnir (5e Equipment)
From D&D Wiki
Weapon (light hammer), artifact
The hammer of the god, Thor Odinson. The History of Mjolnir. A hammer from the Norse gods of Asgard. Forged by the dwarves per the request of the allfather, Odin, for conquest and protection. It was made from a powerful metal called Uru and forged using the heat from a dying star. Eventually, it was passed down to Thor, God of Thunder in order to harness his power and increase his strength.
Worthiness. Upon this hammer is an inscription of an enchantment, placed there by the allfather, Odin. The enchantment states, "Whosoever holds this hammer, if he be worthy, shall posses the power of Thor." In order for one to be "worthy" that may be up to the DM. However, most wielders of the hammer have been willing to uphold a greater good and sacrifice to uphold it. If someone who is unworthy attempts to lift the hammer, they will feel as though they are attempting to lift an impossible weight and the hammer will not budge. Those near death or dead have also said to have been resurrected by the hammer, even saying Thor himself was once resurrected by it.
The Hammer. A throwing hammer with a large hammer head. This hammer deals 3d10 bludgeoning damage and when thrown, on a hit, it stuns all enemies around it in 50 feet. It can be returned to its thrower as a bonus action, as long as they have an open hand. As an action, the user may also use the hammer to gain a fly speed of 30 feet, so long as they hold the hammer. While doing so, they cannot use the hand holding the hammer.
Power of Thor. While wielding this hammer the user gains the ability to summon lightning. As an action, the user holds the hammer to the sky, casting lightning bolt without material components or expending a spell slot, using Strength as their spellcasting modifier. In addition, as a bonus action, you may summon a bolt of lightning to don or doff your armor instantly and change the appearance of the hammer. The hammer may look like a cane, an umbrella, or other item that one might carry with them.
Destroying the Mjolnir. The hammer may be destroyed by a god or more powerful being such as Hel, Norse Goddess of the Underworld.
