The developers of Honkai: Star Rail have released a new trailer for Kastoria, whose banner will appear in the game tomorrow.
Kastoria is a Quantum-type limited character who follows the Path of Memory and uses her own and her allies' health as a resource to summon a dragon that unleashes its power on her enemies.
As the Daughter of the River of Souls, Kastoria, a Zlatius who seeks the core of the flame of "death", accompanies the souls of the dead to the "other side", carefully preserving their memories.
