Hope – Saboteur Crystarium

Character Hope
Role Saboteur
Like Sazh, Hope is one of two Characters that can inflict every Status Ailment in the game. However, Hope exclusively gets multi-target versions of these debuffs (as well as the standard Dispel). This makes Hope an effective Saboteur against groups, but since his Abilities cost three times as many ATB segments, he's a liability when you're only looking to debuff a single target (which is usually the case). He can't even use two debuffs in a round without the Nue.

Fang – Saboteur Crystarium

Character Fang
Role Saboteur
Though she lacks Vanille's Death Ability, Fang is perhaps the most effective Saboteur in the game, though her one glaring weakness, an inability to inflict Poison, is a problem against many of the toughest foes in the game. She also lacks the defense-lowering multi-target debuffs (Deprotega, Deshellga, Imperilga), but as a general rule you're only attacking one target at a time anyway, so this is not a big deal.

Hope – Commando Crystarium

Character Hope
Role Commando
Hope's biggest disadvantage as a Commando is his low strength stat, but then, he gets Ruin right away so that shouldn't be a big issue. In fact, Commando can be very effective for Hope against enemies that are weak against Magic but resist most Elements. He lacks many auto Abilities, notably including Launch, making him a poor choice as your lone Commando, but then, you're not likely to use him in that Role.

Hope – Medic Crystarium

Character Hope
Role Medic
Hope has access to every Medic Ability, which combined with his high Magic stat makes him the best Medic in the game. He is one of only two Characters (along with Vanille) with access to Curaja, a vital Ability when dealing with powerful multi-target attacks from the game's tougher foes.

Hope – Ravager Crystarium

Character Hope
Role Ravager
Hope is the best Ravager in the game, provided your target is not more vulnerable to Physical than Magic attacks. The only Abilities Hope lacks are the -strike Abilities, which is usually fine but will occasionally make him virtually useless. Hope also has the Last Resort special Ability, which will very rapidly build the chain bonus of a staggered target.

Hope – Sentinel Crystarium

Character Hope
Role Sentinel
Despite having the lowest HP in the game, Hope makes for a fairly interesting Sentinel. Like Lightning, he doesn't get Challenge and favors Elude over Mediguard and Steelguard, but Hope also gets the counterattack Abilities, Entrench and Vendetta. He's fun to play around with, but not much use against truly powerful enemies.

Hope – Synergist Crystarium

Character Hope
Role Synergist
Hope, like Sazh, eventually gets almost every basic Synergist Ability (though he gains Veil over Sazh's Vigilance). Until Chapter 10, however, Hope is primarily a defensive Synergist, with Abilities like Protect, Shell, and Bar-spells. Which of the two is more useful depends largely on how hard the enemy in question hits.

Lightning – Saboteur Crystarium

Character Lightning
Role Saboteur
As a secondary Role, it's not surprising that Lightning has a rather limited set of Saboteur Abilities. She lacks any way to inflict Slow, Curse, Daze, Fog, or Pain, and also lacks Dispel, which can be a problem against some foes. However, she does get both the single- and multiple-target forms of Deprotect, Deshell, Imperil, and Poison, making her quite good at lowering defenses of single enemies or entire groups.

Sazh – Saboteur Crystarium

Character Sazh
Role Saboteur
Sazh is a very effective Saboteur, gaining access to every single-target debuff in the game. In fact, he's one of only two Characters that can inflict every possible status ailment (the other being Hope). Because he relies on single-target debuffs, he's not very effective against groups, but then, Saboteurs are generally most important against singular, powerful enemies anyway.

Snow – Saboteur Crystarium

Character Snow
Role Saboteur
Snow's Saboteur is the complement to Lightning's, as he lacks the defense-lowering debuffs Deprotect, Deshell, Poison, and Imperil, but has full access to single- and multi-target versions of Slow, Curse, Daze, Fog, and Pain. Also like Lightning, he lacks access to Dispel. If you're fighting an enemy with powerful offensive abilities, Snow can be very effective, but he won't help you deal much damage against them.

Vanille – Saboteur Crystarium

Character Vanille
Role Saboteur
Vanille is a very effective Saboteur with a variety of Abilities, though she is more concentrated on defense-lowering debuffs. She cannot inflict Slow, Curse, or Daze, and also lacks Fogga and Painga, but has single- and multi-target versions of every other Saboteur Ability. Beyond that, she has Death, a unique Ability that either just kills a target or deals a large amount of damage to them. Since very few non-boss enemies are actually immune to Death, you can get cheap, fast kills against a number of difficult foes (up to and including Adamantoises) with it.
