Paladin

Paladin is a slang term for a character with Warrior as the primary profession and Monk as the secondary profession. It is derived from other games where "paladin" is often a warrior class with healing abilities.

''The Paladin is the hero's hero, dealing damage from one hand and healing from the other. Adrenal sword attacks damage enemies while preserving Energy, and Monk healing skills keep the party healthy. By attacking enemy attacks and maintaining the party's Health, this character takes the heat off allies allowing them to fight more effectively.''
