Samurai sword amp thing could be little attachment at the end of the sword. Like a more powerful sheath.
Scopes and sights no because that defeats the object of MELEE weapons.
OR maybe you could sort of..weld an attachment onto the sword.
Maybe something like a electricity current provider adding eletric dmg...or a PH balance manipulator that makes the sword go really corrosive and make acid dmg.
OR maybe im getting ahead of myself here
