Unlocking the Serpentbone Blade in Elden Ring: A Guide

With a menacing appearance, the Serpentbone Blade in Elden Ring is crafted from the bone of a serpent and brims with lethal poison. This katana is favored by the assassins from Volcano Manor, who wield it to dispatch their foes in excruciating fashion.

In this guide, we’ll walk you through the process of acquiring the Serpentbone Blade by following a distinct questline, and we’ll also show you how to utilize this weapon to create a powerful strength-based build in the game.

Where to Find the Serpentbone Blade

To get your hands on the Serpentbone Blade, you must progress through Tanith’s questline until the second assassination.

To initiate Tanith’s quest, head over to Volcano Manor and speak with her in the throne room. Accept her invitation to join Volcano Manor and you’ll receive the Drawing-Room Key.

Next, go to the room where Rya is located. Interact with the letter on the table to unveil your first assassination target, Old Knight Istavan.

After you take down Istavan near the Divine Bridge in Stormhill, return to Volcano Manor and chat with Tanith to receive the Magma Shot.

Now, head to the room that houses Knight Bernahl. Read the second letter to discover who your next target is.

Locate and eliminate Rileigh the Idle on the Altus Plateau. Then, return once more to Volcano Manor to meet with Tanith. She will then reward you with the coveted Serpentbone Blade.

You’ve earned this powerful weapon, but you can choose to continue Tanith’s story to gain insight into her motivations.
