Thanatos is one of the main bosses that players can fight in Persona 3 and use their Evoker against. As such, it is not surprising that many players are wondering what level he is and what they should be in order to fight him. Thanatos is level 64 when you fight him and one of the most powerful Shadows bosses in the game. Our quick tip for taking him out is to watch out for the fear-based attacks that he has. If anyone gets the fear status on them, be sure to remove it immediately as he has a follow-up attack that instantly kills them. Furthermore, he reflects dark-based attacks, so you need to make sure not to use any dark elemental attacks at all. Thanatos is at least weak to light-based attacks, so be sure to focus on those at least.
