Lævateinn

Lævateinn was forged in the underworld by Loki (who of the Æsir is the one most associated with dwarves) near the doors of death itself, spoken of in the very late Eddic poem Fjölvinsmál. Some historians believe its translation ends with ‘wounding wand’ while others claim it is ‘wounding twig’, similar to the word for magic staff (gambantein). Either way it is this weapon and this weapon only that can kill the golden rooster Víðópnir (which sits in the branches of Yggdrasil and may be tied to Ragnarök, or possibly be another name for Gullinkambi) so that its wing joints (the only things that will suffice) can be used to distract the dogs guarding the flame-encircled castle holding Menglöð, a maiden fated to be married to the hero Svipdagr. The runed weapon awaits within however, protected by the jötunn Sinmara (a _storm giant_ ) who will only exchange it for a tail feather from the golden rooster—that can only be harmed by the very same sword, creating a paradoxical task. Its forger and the owner of the chest that contains it can reveal the secrets to bypassing the 9 locks holding its prison closed, although Loki would only ever do so if a cunning price is attached...

LÆVATEINN

Until you are attuned to this staff, it appears to be a rotting quarterstaff or battered longsword. After you have attuned to it however, runes glow along the length of the wood or the blade.

This staff can be wielded as a magic quarterstaff that grants a +3 bonus to attack and damage rolls made with it. While wielding it, you can use a bonus action to transform it into a magic longsword or back.

The staff has 10 charges for the following properties. It regains 1d8+4 expended charges daily at dawn. If you expend the last charge, roll a d20\. On a 1, the staff loses its properties and becomes a nonmagical weapon (whichever form it is in when the last charge is expended).
