In Elden Ring, you must slay Yura, Hunter of Bloody Fingers, to obtain the Nagakiba katana. Yura, the Hunter of Bloody Fingers may be found beneath the arched remains east of the Seaside Ruins Site of Grace. He’s an NPC who won’t fight you until you strike him a few instances first, and once he does, the total duration of Nagakiba’s blade makes him hazardous.
How to obtain the Nagakiba Katana?
Kill Yura by withdrawing away from his campfire into an open location southwest of it, because there is plenty of space to keep him at a comfortable distance. His strikes have a large range, but they are primarily sluggish and recover slowly.
Avoid them by stepping away or rolling to either side of him, then counterattacking with long-reach, thrusting blows. He only has one health tank, but after that’s depleted, you may just tire him out.
Yura will drop the Nagakiba katana after being defeated, which is one of the greatest katanas in Elden Ring owing to its exceptionally long blade, which allows you to poke at adversaries from a long distance like a polearm while simultaneously having the quicker slashing speed of a sword. Guarded Damage Negation is also somewhat better than a standard katana.
