Sekiro: 10 Helpful Tips & Tricks To Defeat The Final Boss

Obviously you can use whatever prosthetics you like that suit your style, but some good choices include the shuriken and the axe - especially if you've maxed them out.

However, none of them do a tremendous amount of damage and you may be better off using those emblems for the Spiritfall techniques if you've beaten the Headless.

Before you do though, it's worth considering the loaded umbrella, especially if you've upgraded it to Lotus level.

It's particularly good when Isshin breaks out the spear for the first time and starts leaping around and trying to slam you (tee hee).

When he's in the air simply open up the umbrella and his attack will do nothing then press attack to unleash some of that fury back and inflict a little fire damage too.
