A sinister looking katana made from the Serpent Bone, the Serpentbone Blade in Elden Ring is packed with deadly poison. Used by the assassins of Volcano Manor, this weapon is used to kill their enemies in the most painful way possible.
In this guide, we will tell you how to obtain the Serpentbone Blade by progressing a unique questline and how you can use it to craft an amazing strength build in the game.
Serpentbone Blade Location
Serpentbone Blade can only be obtained by progressing Tanith’s Questline to the second assassination.
To start Tanith’s quest, make your way to the Volcano Manor and talk to her in the throne room. Accept her offer to join the Volcano Manor and receive the Drawing-Room Key.
Go to the room where Rya is. Interact with the letter on the table to get your first assassination target, Old Knight Istavan.
Once you kill Istavan near the Divine Bridge on Stormhill, return to Volcano Manor and talk to Tanith to receive the Magma Shot.
Go to the room where Knight Bernahl is. Read the second letter to learn about your second assassination target.
Find and kill Rileigh the Idle on the Altus Plateau. Once again, return to the Volcano Manor and talk to Tanith. This time, she will reward you with the Serpentbone Blade.
At this point, you have your reward, but you can continue Tanith’s Questline to learn about her motivations.
