Elden Ring - How to get Bolt of Gransax (Legendary Weapon at Leyndell)

If you watched Elden Ring 'Rise Tarnished' trailer before, there's a scene where our character is face to face with Starscourge Radahn and throwing a lightning weapon at him. That is a legendary weapon named Bolt of Gransax, and can be missable if you didn't pick it up when you're exploring Leyndell.
In this video, I will show you the location and how to get Bolt of Gransax.

Thanks for watching :)
