Final Fantasy V Job Classes
"Valiant warriors who protect allies low on HP."
Take hits for allies who cannot protect themselves.
Notes: A character with Cover will absorb Battle and Special attacks meant for other characters, but only characters that are crouching down (having 12.5 % of their maximum HP or less). If the character in question has Petrify, Zombie, Dead, Sleep, Paralyze, Confuse, Berserk or Stop set, or is off-screen, Cover won't activate.
Completely absorb a direct physical attack.
Notes: After using !Guard, the character will not perform any action but to sit there, guarding. The guarding character will not take any direct damage from physical hits, though the Sap status caused by the physical hit will still damage the character. Counterattacks are still activated, so physical attackers can be completely locked down by a combination of !Guard and the Counter support ability.
Use both hands when wielding swords, katanas or axes to inflict twice the damage.
Notes: Will raise any character's Strength to base Freelancer Strength + 13. In addition, Swords, Knightswords, Axes/Hammers and Katanas, in addition to those weapon groups, the Staff, the Flail and the Morning Star may be held in two hands, doubling damage done. No shield can be equipped while this support ability is active.
Gain the ability to equip shields.
Notes: Shields can be equipped.
Gain the ability to wear armor.
Notes: Heavy Armor can be equipped. This only includes armor, not shields, heavy helmets or gauntlets.
Gain the ability to wield swords.
Notes: Will raise any character's Strength to base Freelancer Strength + 23. Also, Swords and Knightswords can be equipped.
The Knight is the first heavy armor Job you get, and it will not get outclassed in the physical powerhouse department. The Knight has the highest Strength of the original Job installment, and you won't be getting the slightly more powerful Gladiator Job in a long long time. The only heavy armor Job with more Stamina is uncontrollable and slow. The Knight is the only Job that is able to equip the powerful Knightswords as well as the only heavy armor Job with a support ability that helps out the team. The Knight is simple, really, but good at what it
Job Ability Summary
The Knight is the essential starting point of any heavy armor characters. Two-Handed helps out Berserkers, Samurai, Gladiators and Mystic Knights alike. The Equip Knightstuff abilities will only find meaning it you multiclass outside of the Heavy Armor Jobpool, and if you're sure you won't need extra options in a boss fight or dungeon, Equip Shields can really rank up a mage's survivability. Ninjas can benefit from two Knightswords, and the Strength boost comes in handy as well. !Guard is useful on Monks to make units physically invulnerable while still doing damage (through Counter). Cover is a triviality.
Transfer to Freelancer
Nice Strength and Stamina bonus (though not as high as the Monk's). If you play like a pro, Cover should never have the opportunity to kick in at all, though as a safety net it's better than nothing. A Mastered Knight turned Freelancer is actually a better knight than the Job itself due to equipment choices such as a Ribbon and more Magic Power to utilize a Rune Blade.
