Aventurine joins the roster of Honkai: Star Rail as the second limited Preservation 5-star character, offering players an entirely different defensive option compared to Fu Xuan, especially for those who prefer shielding over damage mitigation. Furthermore, unlike other shield-generating characters, Aventurine can provide a stackable shield for the entire party through his skill, making him an excellent choice for tackling difficult content, especially if players struggle to keep their party alive.
