Whether or not you should kill Yura, Hunter of Bloody Finger in Elden Ring really depends on what you want, both in the short and long term. If you kill Yura, then you will instantly get his long Nagakiba katana, without having to go through a long and difficult task. However, you can get the Nagakiba katana without killing Yura, if you have the patience, skill, and perseverance to do so.
After first talking to Yura, the Hunter of Bloody Fingers, you can head to the ravine northeast of Lake Ahgreel and help him kill the Bloody Hunter Nerijus and get the Reduvia, an extremely powerful dagger. Next, you’ll have to slay the dragon at Lake Ahgreel, which isn’t easy at all, then help Yura in another battle, this time against a Bloody Finger Ravenmount Assassin. Finally, after you defeat the invader at the Second Marika Church in the Altus Plateau, Yura will give you the Nagakiba katana. You’ll then have to survive the battle against Eleonora, which is tough, but rewards you with another powerful weapon, Eleonora’s Poleblade.
If all of that sounds too much trouble, then you should just kill Yura the first time you meet him, and then run away with his katana. However, if you want to have two other powerful weapons as well as Nagakiba, then you should not kill him. Instead, you should try to complete your task.
