This is my 3rd time playing Sekiro. Lies of P really gave me a lot of Sekiro nostalgia And for sure Lies of P is amazing! I can't wait for the DLC. For me, Lies of P was the game of the year.
First, you unlock it from the As part of Shinobi Arts skill tree. It costs 2 XP points. To use it in combat you just press the circle button without pressing a direction on the analog stick. It only works against thrust attacks. That includes weapons and also kicks/punches.
Instead of repeatedly trying to fight against these particular enemies just run away Instead. It's not mandatory to defeat every single enemy you come across in the game after all. I'm currently stuck on the water temple boss battle myself so I've taken a break and returned to playing BOTW on my switch lite at the moment.
BRUHHHHHHHH...... I'm almost done with the map and I'm barely putting that to use. I'm behind on uploads but you gonna see I basically just wondered around to unlock them and eventually used the hover bike.
