The Red Fang is the spiritual successor to the Red Hill, resembling a one handed axe. Once the user has drawn enough It can generate a blade that's around 20 meters long using blood any target (or load the weapon with blood or any other replacement substance available before it's use). The shots, however, are limited to the amount of blood collected, so it's better to be wary about that. Just like the Red Hill, by expanding a larger aount of blood, the Red Fang can create a shockwave which effectively disintegrates any target in the immediate area.
