Benefits

Marcius marveled as his body was filled with the rush of wild and powerful energy. It was distinctly different from the rush he got from absorbing the Eternal Flames Spirit as his second spirit beast.

Back when he gained both the Storm Dragon King and the Eternal Flames Phoenix, it was such that his power and energy reserves nearly doubled with each accusation of the primal spirit beasts. But this feeling was different.

This time, there was no quantifiable increase in the amount of his energy reserves. He did not get stronger in that sense.

No. This was a different kind of power-up.

Before, he had three different energy sources in his body. The lightning energy from the Storm Dragon King, the fire energy from the Eternal Flames Phoenix, and the divine energy from the Solas Mark. Now, in a similar manner, he had a fourth kind of energy, which was probably the dragon flames energy he got from the blood of the Scarlet Bright Dragon.
