The Archer in Disgaea: Hour of Darkness is an unlockable class. They are the only class (other than the Majin) who have an 'S' ranking for BowWeapon Mastery. Sadly, it is the only weapon that the Archer can use effectively, as at best they can achieve only a C rating with their second best weapon, the Gun.
To unlock the Archer, a character on a player's team must have a BowWeapon Mastery level of 3.
A level 100 Archer is also needed to unlock the Angel class.
Archers come from the all-female society of Badre, an ice mountain village. They have a unique social system led by the Sevria. Archers can listen to the wind and deduce its strength and direction. Children are born from the roots of the large tree at the center of the village. They only like to use a bow and arrows.
