Receive Kodama Blessings
As you make your way through Japan, you will occasionally find little green yokai hiding around the area. They’re often found hiding in little nooks and crannies, but are easy to spot because of their bright green color. If you spot one, make sure to go interact with them and send them back to the shrine. Collecting the little green guys will unlock Kodama Blessings at the shrine, most of which can be incredibly helpful. For instance, there’s a healing blessing which increases your chances of finding healing items – a handy boon, especially if you find yourself constantly running low on Elixirs. Do note that Kodama Blessings will cost you a bit of money, but it’s nothing too crazy.
There’s also a Kodama Blessing that increases your chances of finding raw materials. When you’re just starting out in Nioh, this won’t seem terribly important, but I advise picking that Blessing once you’ve got a good handle on the game, because that’s how you get the really good weapons and armor.
