The Paladin has strong Strength, Speed and Wisdom. To open this class, a character must have mastered a number of skills from both the Priest and Fighter skill sets. In Dragon Quest VII, the paladin has a low chance of killing the enemy instantly, regardless of remaining HP. This chance rises when the higher rank the paladin is.
Causes ~200HP in wind damage to one group of enemies, does extra damage to undead monsters
The Paladin's innate ability to instantly kill one enemy is unreliable. It comes very randomly and doesn't work on bosses. As for the skills, Farewell isn't a useful skill except as a last resort. Guardian and Scapegoat are sometimes useful except when it comes to attacks that hit the entire party. For example, if a party member uses Guardian and a monster cast Explodet, the party member that used Guardian will be hit four times by the spell, most likely killing them on the spot. Vacuum is a very useful skill as, like Wind Beast, it grows stronger with higher levels. Multicut is also useful but due to the fact that it only hits one group and it cost 20 MP to cast, you are better off using Vacuum.
In regards to evolution, the Paladin can combine the mastered Dragoon class to become a Godhand and have access to some of the best skills in the game.
Dragon Quest IX
The Paladin vocation is late in the game after completing Quest 106- Taking soul control:
Take 10 hits meant for party members using the Warrior skill Whipping Boy.
Paladin class becomes available
Brunhild at the Mirage Mahal wants to see if you've got what it takes to be a paladin. You need to use the Whipping Boy ability to protect your companions ten times in battle in the Djust Desert.
Hint for solution
Find monsters that hit several times or a group of monsters.
They have good attack and defense but low speed. It can be considered a more battle-ready version of the priest class as it learns many healing and buff spells. Paladins have the unique skillset "Virtue", and can also use skill points to learn Hammer, Spear, Wand, and Shield skills. Their Coup-de-Grace is "Knight Watch," which prevents all damage and status effects, while enraging all enemies to the user.
Their Virtue skillset is worth investing skill points in, regardless of vocation. If you can invest the full 100 points, that character will have 100 extra Resilience and 80 extra HP, drastically increasing the ability to survive tougher battles. Mages would benefit enormously from these bonuses, due to their abysmal HP and Resilience.
