Title and thx in advance

No not really.
Closest to a magic weapon
are the throwing knives they can be upgraded so when they hit an enemie he evaporates into thin air and the body is gone.

Depends on what you mean magic.
Weapons:
Cursed sword. Doubles damage but halves your health.
Dagger that heals 10% on every fifth strike. And strike here means sword strike, you only use dagger for parrying.
Sword that poisons enemy on every fifth strike.

Tools:
Aforementioned evaporation, also smoke bomb can be upgraded to either heal you or make enemies forget you were there.

Also there's one special book you can find Kitab al-Azif aka Necronomicon but it doesn't actually do anything during gameplay.
