It was commonly known that most human magus had a battle power of at least 200 when their Immortal Body was formed upon their ascension to their realm. Afterward, to further temper one's physical strength became increasingly difficult as the state of the body had been defined. Most only reached 300 battle power at the Half Moon stage and 500 at the Full Moon stage. Even the combat magus Izta, who was renowned for his overwhelming strength, only possessed 600 battle power.
Of course, a magus could utilize various ways to further increase their physical power. For example, through products of apothecary, powerful artifacts, and extraordinary skills like [Immortal Gate] the combat magus known for. However, the same was evidently not the case for Cassian.
