you can do it.just open your table via cheat engine and go to the last selected item and check that then go to the item menu in the game and just highlight the weapon(just get to the item that you want to change). there are going to be a lot of info in the cheat engine including the level and the plus level and you can just change them.
I use table the "nioh-1.21.04u5" table and it's so useful! I thank you a lot for it!
But I do not understand, how I can activate the scripts. Do I have to change anything in The Sourcecode to start them?
Btw I read every bit of the 58 pages, but I can't find a solutions on what I have to do... maybe you're all more intelligent than me.... but I hope for your help! If my English is bad... I'm from Bavaria... but we have good beer!
