(Choose the skill or Authority that you want to evolve...)
In front of Evan's eyes, the names of all his Skills and Authorities appeared. He looked at them for a second and, after considering everything, he chose to evolve the Death Guardian Authority.
The reason he chose Death Guardian instead of Master of Shadows was because of the short duration of the Death Guardian Authority.
Although the Death Guardian authority was very powerful, its duration was just five seconds, and he was hoping he would be able to use it for a longer period of time after evolving it.
The moment Evan chose Death Guardian for evolution, the energy of the evolution essence drop inside his body started to move. He felt the energy moving inside his body and waited for his authority to evolve with a look of anticipation on his face.
