A God Amongst Men, or Mages?

My name is Joseph Amida after the Japanese god of death. I know everything there is to know about anything there is to know about. I collected knowledge all my life, whether it be about fighting, human anatomy, videogame skills, tactics, weapons, foods, plants, particles, the higgsfield, and more, much more. However I died, getting struck by strange lightning. Now I'm stuck in a world where knowledge is power, good thing I studied my whole life.
