Lightning Hammer Mjölnir (雷槌(らいつい)ミョルニル, Raitsui Myoruniru?) is a legendary-class one-handed hammer in ALfheim Online that was rewarded to Klein for choosing to rescue Freyja (Thor) during «The Holy Sword of the Ice Palace» quest. The hammer is currently in the possession of Lisbeth.


The Lightning Hammer Mjölnir is a fairy-size version of Thor's golden hammer.[1] It is a war hammer with its head blunt on both sides.[2] It also has three jewels inlaid in the middle of its head.[2]



After Asuna, Kirito, Klein, Leafa, Lisbeth, Silica and Sinon defeated Thrym, Thor rewarded Klein with a fairy-sized replica of his hammer for helping him exact revenge on Thrym for stealing his hammer. As Klein did not train any hammer skills, he gave the hammer to Lisbeth, asking her not to dissolve it into ingots.
