I beat him

After 5 hours, I beat Ozma.

This game was pretty awesome. And after 58 hours I just wanted to thank you all, your advices and suggestions on this Reddit were accurate.

My advice for all Sekiro enthusiasts (like me) that will start the game: not just block as it doesn’t make a huge impact , but use all the skills that the games has. And most important learn to deflect in the early game, I learned it at the end with Ozma and the boss was less difficult and more funnier.

I will rest for the game a little to start playing Clair Obscur and Oblivion but sure I will get the platinum.

Thanks!
