Reincarnate into the Game World and Become a Top Numerical Monster

Mr. A: "Isn't that a profession with very limited use cases? Most people want to play those with high mobility and high error tolerance, right?" Me: "It depends on personal preference. I like players whose left fists do more damage and their right fists do more damage." A: "However, no matter how high the physical and magical attack power of this game is, it is limited by the enemy's increasing double resistance. It is too unrealistic to expect to instantly kill the opponent every time." I laughed and explained to Mr. A the damage mechanism of this "very limited use case" character. A: "What does it mean to be able to receive a multiplier bonus of physical attack power and spell damage while also receiving an area damage of 5 times the real damage based on this damage?"
