Yeah, you'll just load your save and all the gates that are locked now will be open.
Related, YouTube people are fucking weird. So many videos showing how to exploit past the locked spirit runes to kill Raiju now and get gear way above your level and people just gobble it up like it's not pants on head retarded to do that to ruin the $70 game you're about to buy...
Final Fantasy: Stranger of Paradise had a similar thing where you could farm a high-level Marlboro or something and get super-strong equipment drops, breaking the game before too long.
Didn't the same people make that game as this game? The Samurai/Ninja switching in Nioh 3 is literally the classes in SoP. Outfit changes and everything.
I beat Sekiro, Stranger of Paradise, and Wo Long. All of them took time/patience/focus, but were very doable. And yet Nioh kicks my ass. It feels like I'm just missing something fundamental about these games. I slash and dodge, slash and dodge. A bit like Souls, which I guess you're not supposed to play like. The dodge button being moved around from Souls is super annoying and there's no way to change it.
Main issue is that the enemies have tons of poise. I resumed my game about a third to halfway through Nioh 1 and I have an electric katana that looks awesome, but I can barely win any fights. Enemies have hyperarmor-like poise so I can't stall them for a moment, I have to try and get behind them so I can bash away for a couple seconds before getting out of the way.
The other main issue is that enemy attacks have insane tracking. I have to wait until they strike and then dodge super-fast because if I simply move out of the way of an incoming attack, they spin around mid-attack and track me with it. I can only really strike between enemy attacks, and only for a second because of their poise.
Basically every fight is a huge struggle and it feels like I'm playing wrong. I might have to give up on this series (yet again) but I really don't want to. Nothing has any "weight" like a Souls game and I don't feel like I've got a gameplay loop to adhere to (like Sekiro I'm trying to break enemy posture, Wo Long I'm looking for big attacks to parry....Nioh is just zip around, stick and move, feel super weak at all times).
If anything does succeed in hitting me back, my character has basically no poise and gets knocked around like a ragdoll; it's common for me to lose 75% of my health in one enemy attack if they land a couple hits before I can get away. I can take about 3 hits, maybe 4, from even trash enemies, and that's with the best available armor on. Level 54, and I'm doing missions that are labeled low-40's.
