Elden Ring Black Knife Notes & Tips

• Black Knife can be upgraded by using Somber Smithing Stones.
• This weapon can't be infused with Ashes of War, nor can it be enchanted with Magic or boosted by Consumables.
• This weapon has a unique R2 moveset shared with the Blade of Calling and the Erdsteel Dagger, that performs quick double slashes. 
• Weapon Skill: Blade of Death - This projectile will reduce the Target's Maximum HP for a period of time while also reducing their Current HP. For further notes and tips, go to the skill's page.
• While this weapon is primarily designed with Dex Faith builds in mind, the Blade of Death projectile's damage is only affected by Faith scaling, meaning that a Strength Faith build utilizing Maliketh's Black Blade or the Black Blade incantation can still benefit from this weapon solely for the weapon skill alone.
• This weapon may have drawn inspiration from an African hybrid knife/axe known as the mambele.
• Sell Value:  

   100.
