History GameBreaker / FinalFantasyTactics

** Meliadoul in the UpdatedRerelease gains the ability to use her powerful sword techs (That Orlandeau has) on nonhuman enemies - which means that, even ''without'' giving her that ''Excalibur'', she can one-shot most human enemies you face ''and'' gain the versatility of Agrias, Orlandeau, and the Dark Knight class. Meliadoul was already a TierInducedScrappy in the original, but in "War of the Lions"? The question isn't whether or not to use Meliadoul when you have Orlandeau... so much as it is "Why not use ''both''?"

* Meliadoul's Unyielding Blade can hit enemies without the specific equipment in the remakes (which means not even monsters are safe; they don't have any equipment to break but the attacks still do major damage) and while she isn't Orlandeau, Meliadoul still hits pretty damn hard with her skillset. By default she actually hits harder than Agrias, but lacks the (surprisingly useful) status effects and the [=AoE=] attacks.

* Fairly early on in the game, Ramza has access to Yell/Tailwind, which ups his speed by one per use. Reuse it enough, and you'll start getting extra {{turn}}s, and he can use it on other characters. The thing is, the faster you get, quite literally the faster you ''can'' get. The ability snowballs once you get underway, to the point where Ramza will be getting up to eight turns in a row, which is eight turns he can be upping another character's speed.

* In the PSX version at least, any unit participating in battle with other unit types would gain a quarter of any JP those units gained, meaning a Level 2 Ramza could leech enough JP from others' actions to actually progress to other jobs and eventually master them all, without taking an Action. This way, random encounters' levels are still low, but Ramza still has ludicrous skill sets and the option to level up in whatever job the player wants (or spams the stat growth, as mentioned later herein with the Degenerator).

** [[VideoGame/FinalFantasyXII Balthier]], in the UpdatedReRelease, comes with superb equipment, all of Mustadio's skills and upgraded Thief abilities (no more will you have to worry about beating <15% success rate). His barrage skill is akin to attacking twice with any weapon, it's unblockable, undodgeable and if he uses it with his default gun he can easily kill any unit within two rounds from across the stage.
* Any ability that don't require "casting-time" breaks the game due to bypassing Charge Times, to which about any class save for the most basic ones is limited. It's also the reason why a mastered Arithmetician is ''horribly broken''.

The ability snowballs once you get underway, to the point where Ramza will be getting up to eight turns in a row, which is eight turns he can be upping another character's speed.

** The ''War of the Lions'' takes this even further, with the ability to gain the Tynar Rouge accessory, which grants permanent Haste, Protect, Shell, boosts Holy and add +3 to Strength and Magic. Give that to Agrias and watch as she basically ''rivals Orlandeau's feats''.
* Cloud's Limit Break ''Finish Touch''. It is as fast as a level-one White/Black spell, costs no MP, and causes KO, Stone and Stop. Sure, you still have to build him up from level 1 and use the weak Materia Blade, but attack power is irrelevant when you're hitting with an insta-kill move. The only stats that matter for Cloud are Speed (simple, make him a Ninja) and HP. The Time Mage's Quickness ability also helps, making the low casting time for Finishing Touch even shorter.

* The UpdatedReRelease adds "Dark Knight" as a job class. Make one with Darkness, Iaido, Shirahadori, Safeguard, and Move+3 as abilities, then equip him with Excalibur, Aegis Shield, Crystal Helm, Mirror Mail, and Featherweave Cloak. Especially deadly in the endgame, as Brave increases are permanent in a 4:1 or so ratio, give him 20 Brave in one encounter and he keeps five after the fight. You could easily have a character untouchable by magic with an 8% chance of being hit from behind. The only weaknesses are summons and non-reflectable magics, which can be avoided by virtue of the shield and cloak, and characters with holy blade abilities, like Weigraf and Loffrey -- the latter of which is foiled by Safeguard. Ramza? With Shout? Hoo-lee-crap. Strategically position a mime? Ow.

** Give a Ninja the "Equip Spear" ability, the "Jump" ability, and optimize them with all of your speed boosting equipment and the Ultimate Javelin. For added effectiveness, learn the Lancer/Dragoon's best Jump skills. You'll have a warrior able to inflict 999 damage from eight panels away with the speed of a Short Charged, level 1 Black Magic spell.
* Or the broken combo of the reaction ability "MP Switch" and "Move MP UP" which makes you ''completely invulnerable to damage'' as long as you move.
* One can also raise a monk's level which can permit more damage than any weaponed character. Accumulate ability provides 10 experience and many job points (or something like that) per usage, meaning with enough time, you can level up an entire party (and their jobs) in one match as many times as you want, without doing any damage or casting any magic. Combined with haste spells (which raised speed for the match) characters could have many, many turns while enemies have one. And then you can have dual-wielding on a specific character, use "best fit" in a shop, and TWO excaliburs would be equipped, only costing 10 money a piece. Extra game breaker: only random encounters had level-matched enemies. Formal matches could have your level 99 characters facing off against level 20 enemies.
* Two Dancers, paired with three Mimes. Set the Dancers to Wizzinabus. Set the controller down. Even without exploiting the way the game engine calculates damage, they can usually murder their way through just about anything before the enemy can even reach them.
* Any unit equipped with a Feather Cape and Reflexes also deserves mention. The Feather cape gives a unit 40% chance to dodge physical attacks and a 30% chance to dodge magic attacks, Reflexes doubles both chances and since it's a cape the evade bonus works on back and side attacks so a unit by default gets hit from physicals 20% at most and gets hit from magic 40% of the time. The advantage it has on Shirahadori is that it stops most magic attacks and it allows you to evade counter.

* [[GenderRestrictedGear Perfumes]] can turn any female character into a killing machine. Moreso if you equip it on Special Units (like Agrias, Meliadoul or Reis), who are already powerful by their own right. One such accessory, Chantage, gives permanent Auto-Raise, making the wearer nearly invincible (the only way she can be defeated is by Petrify or Blood Suck). Conveniently, the series-standard [[AntiDebufff Ribbon]] is also female-exclusive in this game, so even those weaknesses can be compensated for.
