These are builds I've had the most success with in Perfect Plat 7 attempts. Samurai is generally considered the least effective class for Hellmode but it doesn't have to be that way! Play it safe, be aware of when and where you use your ultimate and never use it outside unless you're familiar with the fire spirit pattern and can get out safely!

The Forbidden Medicine build is also newer player friendly since the smoke bomb, concussion and flash bombs offer plenty of breathing room in a pinch and in my experience, breathing room when you're first starting out is much needed 😂

Now, for those more experienced, on the Forbidden Medicine build, one can swap Spirit Kunai with the sticky bomb from the Weightless Spirit Build and instead of a Samurai Charm run Enjo's Remorse with the same perks. This variant is for players who are experienced enough with Samurai and Hellmode, but also have a team of players who don't get hit that often, rendering Enjo's useless.

Side note, I use Ultimate Damage on Katana and Charm based on preference. Other will prefer Oni Damage instead or a mix between the two (One on the Katana and one on the Charm). I'd say experiment with both and figure out what you like best!

If anyone has any questions or needs things clarified, let me know!
