Final Fantasy XIII/Characters

Properly training your characters to maximize their inherent stats and skills will help you build strong parties for combat. For a large portion of the game, your party will be fixed to go along with the story, but whether forced into a certain party or creating your own, knowing who should be training what role and how to combine them into useful paradigms is the key to success.

There are six playable characters and up to three can be in a party at a given time. Each character starts with one or two roles they can research, but will quickly have access to all three of their primary roles. Later in the game the rest of the secondary roles will become available, though at much higher cost to research. Each character also starts with certain stats and a weapon, and each one will eventually be able to gain their own Eidolon in the course of the game.

Lightning

 * Primary roles: Commando, Ravager, Medic
 * Secondary roles: Sentinel, Saboteur, Synergist
 * Suggested specialization: Commando and Ravager
 * Eidolon: Odin
 * Starting weapon: Blazefire Sabre
 * Maxed HP: 20,000
 * Maxed Strength: 1,700
 * Maxed Magic: 1,700

Lightning can be described as the jack-of-all-trades—she does fairly well in most roles, but never specializes in one. In the early portion of the game, Lightning should focus on the Commando role and let Vanille, Sazh, or Hope stagger the enemy. However once Fang joins the team, it is recommended that Lightning switch to the Ravager role, as Fang's strength and Commando abilities (Adrenaline, Deathblow, and Highwind) outshine Lightning's. She may not have the highest magic, but her speed allows her to quickly stagger enemies. Lightning can learn all the elemental "strike" and magic abilities up to "-ra" level with the addition of Thundaga. She also has access to her unique ability, Army of One which raises the enemy chain percentage. As a Medic, Lightning will reach her peak once she learns Cura, and can act as a back up to Hope or Vanille when the party is severely injured. She also can learn Raise which is useful when the main healer of the team is incapacitated. As a Sentinel, Lightning will only learn one command ability: Elude. This is an advantage if the enemy only uses physical attacks, otherwise it is not recommended role. Lightning is a serviceable Saboteur and Synergist. She will learn Deprotect, Deshell, Imperil and Poison as a Saboteur and Bravery, Faith, Protect, Shell, Vigilance, and the "en-" spells as a Synergist.

Sazh

 * Primary roles: Commando, Ravager, Synergist
 * Secondary roles: Sentinel, Saboteur, Medic
 * Suggested specialization: Ravager and Synergist
 * Eidolon: Brynhildr
 * Starting weapon: Vega 42s
 * Maxed HP: 27,000
 * Maxed Strength: 10,000
 * Maxed Magic: 10,000

Sazh Katzroy has the lowest base strength and magic, but don't let this fool you into not including him in your team. Sazh's weapons provide the highest stat boosts with some useful abilities. For the majority of the game, Sazh should be a support character. As a Commando, Sazh is overshadowed by the others, he is missing the important "Launch" ability and his animation speed is slow. However, Sazh can deal a lot of damage to groups of enemies or a large enemy with his "Blitz" ability. Sazh is pretty good as a Ravager due to two of his weapons' abilities helping him in staggering enemies. He learns all the Fire and Thunder abilities, but is missing the Ice and Water abilities. His unique skill, Cold Blood, raises enemy chain percentages and can be found in the Ravager role. Sazh's true skill lies in his Synergist role—the only person to rival him in this role is Hope. Sazh learns all the buffs, except for Veil. He is also the first person to learn the very important "Haste" buff. Sazh is a decent Sentinel with his high HP. However he is the only character that is missing "Reprieve" (an ability that prevents 1HKO), which is a big disadvantage for late game. Sazh is surprisingly good at the Saboteur role, as he is able to learn all the Saboteur abilities except for the "-ga" ones, which is actually an advantage because "-ga" abilities have lower success rates. Sazh can learn Curasa as a Medic, but other than that the Medic role should be left for someone else.

Hope

 * Primary roles: Ravager, Synergist, Medic
 * Suggested specialization: Medic and Ravager
 * Eidolon: Alexander
 * Starting weapon: Airwing

Hope Estheim has the lowest strength and HP, but has the highest potential for the magic stat. Along with Vanille, he also has access to all the abilities in the Medic role. His great magic will also be helpful as a Ravager with status-inflicting spells and he can get all the same abilities as Sazh in the Synergist role, except for Vigilance, though he additionally has access to Veil. Due to his weak HP, you'll want to team him up with a strong Sentinel or give him the strongest armor accessories with upgrades.

Vanille

 * Primary roles: Saboteur, Medic, Ravager
 * Suggested specialization: Saboteur, Medic and Ravager
 * Eidolon: Hecatoncheir
 * Starting weapon: Binding Rod

Early on, Oerba Dia Vanille learns some great abilities, like Deprotect, Deshell and Poison in the Saboteur role to help speed up battles. You'll also want to level up her Medic role, since she'll be your only option for a few chapters and she's one of only four characters that can learn the important Curasa ability, and one of only two that have access to Curaja. Although she's missing some good Saboteur abilities like Slow, Curse and Daze, she makes up for it by having the vital Pain and Fog abilities, as well as being the only character with access to Death. Vanille has very high magic throughout the game and better HP than Hope, so getting her highly leveled in all three of her primary roles and using her will be helpful.

Snow

 * Primary roles: Sentinel, Commando, Ravager
 * Suggested specialization: Sentinel and Commando
 * Eidolon: Shiva Sisters
 * Starting weapon: Wild Bear

Snow Villiers has the Sentinel role right from the start, and long term he has the highest potential HP of any character. Additionally, he has access to all Sentinel crystals except for Elude, which means he's one of the few who can use the extremely important Sentinel ability Mediguard. Commando is also a viable option for Snow, as he can acquire every ability except Faultsiphon, he has the special Snow-only Sovereign Fist ability, and he has great strength.

Fang

 * Primary roles: Commando, Sentinel, Saboteur
 * Suggested specialization: Commando, Sentinel and Saboteur
 * Eidolon: Bahamut
 * Starting weapon: Bladed Lance

Oerba Yung Fang is the strongest character and has access to every Commando ability. Additionally, she gets the Highwind ability that only she can use. Fang is strong in most areas, and so can be a good Sentinel, with access to almost all those abilities, and a good Ravager, with access to the four "strike" abilities. She can learn key spells as a Saboteur in their area-of-effect forms, such as Fogga and Painga, and has decent Medic abilities as well, making her a very versatile teammate for a wide variety of paradigms.
