A koto (Japanese string instrument) infused with Slash or Sound magic, able to send powerful magic attacks by plucking its strings. Deadly if given to a competent (and very bloodthirsty) musician.
Obtained via boss drop.
Based on the guzheng (a Chinese string instrument very similar to the koto) used by the blind twin assassins from the movie Kung Fu Hustle.
If blood magic existed a bloody katana like Chikage from bloodborn would be super cool… although with combination with the vampirism fighting style it could still be possible
Rust sword: Like shadow sword but somebody left it outside for a year or two.
Nothing special, just causes gangrene to everything that makes contact with it, including the weilder.
