Includes at least one item that expresses sentience to a degree, commonly by talking to the wielder and possibly people around them.
Alternate name: Sentient weapon
The first video game about Sentient artefact was released in 1993.
Unlike living weapons, these can be quite inorganic and otherwise not exhibit any signs of life. Usually they exist through some magical, demonic, or otherwise mystical means, but even some Sci-Fi style things are appropriate (A.I., in case it's "trapped" into the artefact).
