Magnhild

Magnhild is Nora's weapon of choice.

Description
Magnhild has two forms, one of which is a large war hammer, the other a grenade launcher. When in grenade launcher form, Nora fires what seem to be canisters of pink Dust with a heart shape on the tip. These blasts also appear pink when they explode on impact and are able to at least distract a full grown Nevermore. Individual grenades also appear to have a proximity or remote detonator, as they are seen exploding in the air, similar to a flak cannon or air burst explosive. The grenade launcher itself is fed by a revolver-type rotating cylinder with several individual chambers.

When in hammer form, Nora is able to use the recoil from fired explosives to propel herself through the air in much the same way Ruby does with Crescent Rose. Nora's hammer strikes also appear to be incredibly powerful, as she was able to flip a segment of a large stone bridge with enough force to send Jaune flying over a large gap. Nora is also shown using the recoil from the hammer to accelerate her flight through the air and punctuate her hits. When deployed in this way, Magnhild is powerful enough to shatter the armor of a Death Stalker by forcing its own stinger through its head.

Trivia

 * Magnhild adds to Nora's Nordic theme, as Thor, the god of thunder, is said to wield the hammer Mjölnir in battle. The name is also Old Norse, meaning "strong, mighty" from the root "magn" and "battle" from the root "hildr."
 * The Grenade Launcher form appears to be based on the M32 MGL (Multiple Grenade Launcher) used by the U.S. Army.
 * The Hammer is similar to Medieval European war hammer pole-arms.
 * Magnhild, in hammer form, appears similar in function to the Gravity Hammer from the Halo franchise.
 * According to executive producer Matt Hullum and creator Monty Oum, the idea of an explosive hammer was inspired by a video of a Mexican tradition where explosives are hit with sledgehammers.
 * On the Grenade Launcher there are many exotic designs and decals.
