Sekiro: Shadows Die Twice O'rin of the water guide
This is one of the spookiest bosses in Sekiro: Shadows Die Twice. Without the right shinobi tools, or good deflect skills, this mini-boss can be extremely frustrating to fight. Luckily in this Sekiro O'rin of the water guide we explain a strategy that slowly but surely breaks her down.
When fighting this boss, the easiest way to win is to run away from her. Just keep running from her and circling around her. Every so often she goes invisible and teleports closer to you. When she does this, immediately swing your sword right at her while running. She'll come out of the teleport right into your slash. After the slash, continue to run away and keep circling her.
There are two things to know about this trick, if you're too far from her, she'll block after the teleport. If you get too close, she won't teleport at all. If you're just the right distance though, she'll take a sword swing to the face for free after the teleport. Since the teleport is her only real distance-closer, you're completely safe as long as you swing into this one attack of hers.
One last thing to note is to pay attention to your surroundings. When circling her, if you run into a tree or get stuck on a wall, you can pay dearly for it. Try to turn around and circle the other way if you run out of room.
