Still playing Sekiro.

The art upgrade to recover health every time you do a deathblow is a godsend. As soon as I got it, the whole game just got more fun, because now if I lose health or make a mistake, I can just find an enemy and deathblow them to regain health until I get some back. it was worth spending 5 levels of exp for that. get it as soon as you can, it is worth grinding for.
