Berserkers are innately immune to the Confuse status. Berserkers start to decline in use the further the game progresses, and after a certain point, become irrelevant compared to many other jobs. Due to their low ABP cost to master compared to many other physical jobs, they are ideal to master early on for the bonuses they provide to Freelancers. Mastering Berserker in all four characters in the mobile and Steam versions earns the player the achievement "Skull Buster".
