The Shinobi in Cyberpunk 2077 is a high-speed skill that uses slides and dashes to stay out of danger while cutting apart all your enemies. To level this skill, you need to dash around or get kills with reflex weapons like a Katana or other Blades — or Submachine Guns and Assault Rifles. Being a mobile force of death often gives you the experience to level up your Shinobi skill line.
