Fighter class has the highest max HP (182) class base of any class in the series, a trait it shares with its promotion and the Fell God class. Due to the way the game handles class bases vs character bases, it's impossible to make use of said class base.
Curiously, the map sprite of the Fighter class shows Alm with a shield, despite Alm not using a shield until he becomes a Hero.
