In "World of Warcraft" game play, the Paladin is considered to be a melee-oriented "hybrid class", which is a class that fulfills more than one role. Paladins have various protective spells they extend to party or raid members, the ability to heal allies and oneself, and a unique system of "seals" and "judgments" for combat. Paladins can be 'specialized' at level 10 and above. The three available specializations are holy, protection and retribution. The Holy Paladin specializes as a healer (acting as an armored cleric), the Protection Paladin takes the role of a damage-absorbing "tank" for a group, and the retribution specialization increases the Paladin's ability to do melee damage (representing a zealous crusader).
