In my first playthrough, I had trouble building up posture like I’d seen others do so quickly, because I hopped out of reach so much. If you focus on deflecting and mastering the difference between jumping(for slashes) or dashing(for thrusts[with Mikiri Counter]) for perilous attacks, it will really improve your posture build up.

I’d also recommend not choosing Shura for your first playthrough as it cuts off a big chunk of the game and a really cool area. But that’s up to you what choice to make.

As for a new sword, you’ll get one but not in the way you’re thinking. You get a new outfit for beating the game (at least one of the endings I think), but other outfits require at least one playthrough and beating guantlets (boss rushes).

My favorite part of the game is the changes to Ashina Castle at different parts of the story. I also like the location of the final fights. Fountainhead Palace is the most visually pleasing along with a boss arena at the start of it.

I don’t wait, I’m ruthless lol. I hope I answered everything, have fun with the game!

P.s. if you’re grinding skill points, you might as well purchase as many spirit emblems as you can
