Cursed Blades

The Cursed Blades are a set of spellcrafts that were created by Leidolf's master, each based off legendary swords from Norse Mythology, and powered by the essence of legendary beings, such as the Fire Giants.

The total number is unknown, but Leidolf's master mentioned that he had more, but they were stolen.

Tyrfing
Known as the Bane of Shields, Tyrfing has the power to break through defenses using overwhelming force, in the form of an energy beam. The user's life force is used to empower the blade, and three shots within a time frame will kill the user.

With every use of this blade, there is a set cool down period before it can be used again. Using it twice left Leidolf unable to use it for two years and in a near death state from converting his life force into power.
