The traditional "artifact" of the game, that is, the special suit "Mystery of Twelve Constellations", can be unlocked in the secret room after being completely decrypted. The strongest suit "Thomas Decanel Armor", that is, the clothes of the assassin who stopped you at the beginning of the game, is actually a black thickened version of 1 Dai Artur's assassin's robe.
Eden artifact A, after the clearance of the plot, can use the "Sword of Eden", "although the magic given to it by unknown forces has disappeared".
In addition to being handsome, with the highest attributes and no bright spots, it is not as good as DLC's "Su Jie Eagle", which randomly flashes blinding enemies and is known as the most Qiang Jian. Judging from the series of tasks of the DLC branch line "The Mystery of Su Jie's Heritage", the sword-shaped wall on the second floor of the square church in the new map is actually the place to receive this task. After a while, the stone wall will be removed and you can get it.
Eden artifact B and DLC can get the oil lamp "the head of Saint Denis" after customs clearance, but they can't escape the script of the disappearance of divine power and become eternal lanterns. It is a pure task prop and has no practical use.
