Bouncers have a few unique abilities. They can…
Reduce the amount of damage absorbed after an attack. Bouncers naturally have higher defense (DEF) and resistance (RES) stats compared to other classes.
Cutoff an enemy’s special technique by getting between the range of the attack.
Act as a bodyguard by covering other characters from damage. This skill is particularly useful for frail classes like mages and characters near death.
Shamans, first seen in Disgaea 3: Absence of Justice, return in Disgaea 4 armed with stat decreasing dances. Their first skill is "cursed dance."
