Primordial Soul Lamp

A rare treasure used to house and nurture a strand of split soul. Unlike ordinary vessels, it not only prevents the split soul from weakening over time but also nourishes and strengthens it. With special secret techniques, the nurtured soul can be cultivated into a Primordial Soul Avatar, a type of external incarnation. The user retains control via the lamp, eliminating反噬 (backlash) risks. The avatar can potentially be cultivated to be stronger than the main body.
