History GameBreaker / XenobladeChronicles3

** [[spoiler:Shulk]] is one of the weaker party members in ''Future Redeemed'', but like Riku and Manana, he fares better in the Archsage's Gauntlet due to the Debuff Rate Up/Debuff to Break combination. However, given that he's a BraggingRightsReward, he arguably benefits ''even more'' from the mode's mechanics than they do. [[spoiler:Shulk]] has very high endurance, and his tanking ability depends on the success rate of [[spoiler:Monado Rage]] inflicting its Lock-On debuff; the Debuff emblems therefore make him better at his job, in addition to the same benefits that they provide to Riku and Manana. This also makes him a good "revive bot" for the mode by giving him a Memory Locket, similar to how many players use him in ''Future Redeemed''. His Chain Order, while a weaker version of Ashera's, is still good, increasing the damage ratio a fair amount and granting Power Charge to all allies.

* Clearing both the main game and ''Future Redeemed'' provides access to one more broken Hero: [[spoiler: Rex, who is just as potent in the base game]]. He keeps most of his useful skills, making him one of the few Heroes who can deal ''very'' significant damage in his own right, and has access to both Topple and Launch Arts, making him the best Hero for helping with Art combos. On top of this, while his Heroic Chain is good but nothing spectacular, his Chain Attack completion bonus reduces the opponent's physical defense by ''up to 75 percentage points'' -- an even stronger version of Taion's completion bonus that lets him hit even harder. Furthermore, his GlassCannon status can be mitigated through the greater customizability of the Ouroboros members, allowing a Defender or off-tank such as a Full Metal Jaguar to take some of the heat off him. While [[spoiler:Rex]]'s unlock conditions make him something of a BraggingRightsReward, he can still be used to great effect in postgame, Challenge Battle and NewGamePlus content.

** Taion and Eunie's Ouroboros Orders are easily the most powerful in already-broken Chain Attacks. While unclear wording obfuscates this, their Chain Order effects can cause enemy defenses to drop into the ''negatives'' (especially when stacked in conjunction with Noah's Chain Order setting any enemy defenses to zero), resulting in a flat multiplier to damage across the board. Furthermore, as explained below, their Interlinks can obtain a skill that multiplies their damage even further for every buff/debuff active, so despite a nominally weak effect, you end up with a combination that can do millions of damage per hit.

* While it is a MagikarpPower to the highest order and has a lot of ramping up to do to overcome the ScrappyMechanic of obtaining abilities by hunting Unique Monsters, the Soulhacker class easily outshines most other standard classes by way of being a MasterOfAll capable of fulfilling nearly every role with a myriad of options for arts and skills with customizability akin to the previous game's Poppi QTπ. Also like Poppi QTπ, Soulhacker shines most as a DPS, possessing among the highest attack power arts in the game in Elimination Beam, Transient Bond and Wild Wave, two sources of Power Charge (both to self and AOE, the latter of which is only otherwise achievable via Chain Orders or Signifer), and an excellent set of conditional attack boost skills, though unlike Poppi, it is not the greatest at inflicting break, but it is still very viable. It is pretty telling that the whole party can all run the class and not suffer from CripplingOverspecialization.

* Ashera is a Hero that makes it trivial to get high damaging Chain Attacks. Her Heroic Chain (guaranteed 200% "Amazing" if she ends the turn at the cost of being unable to reactivate) makes it so you can use 3 party members + Ashera on the first turn, and get all 3 party members reactivated with enough TP to ensure snowballing ratio increases for the rest of the Chain Attack and making the downside irrelevant. Her Hero Order (+175% Damage Ratio) is simple, but allows for much more damage overall if achieved early during the Chain Attack. On a side note, her class, the Lone Exile class provides the only Launch master art available, making investments into her class worthwhile.

** The Royal Summoner class, relegated to postgame, isn't amazing because of how slow it is to build up power and only worth investing in for its "Essence of Ether" skill; however, the Royal Summoner hero, [[spoiler:Melia]], while not as strong as Ashera, is a high-tier menace for similar reasons to her. Her unique Arts are superior to those used by an Ouroboros member with the Royal Summoner Class, with her signature [[spoiler: Starlight Kick ([[MemeticMutation ouch!]])]] having a faster animation than the Starfall Art that replaces it for the playable characters. For her Heroic Chain, even if she brings the TP ratio above 100%, the chain doesn't end and you can use another character to bring it even higher, making her similar to Ashera in function but being able to reactivate herself at the cost of not being an auto-guaranteed "Amazing" at the end of the turn -- though with the Veneris Rings, she can help her teammates reach "Amazing" ratings more consistently, as they bump her base TP up to 55. Her Chain Order has the same effect as Eunie's already-broken Order, decreasing opponents' ether defense by 50 percentage points, but it can also ''stack with Eunie's'' to devastating effects and push enemies' ether defense ''even further'' into the negatives; it can be argued that [[spoiler:Melia]] may be even ''better'' than Ashera on Hard Mode because Ashera's Chain Order is severely nerfed by the reduced Chain Attack damage ratios, while [[spoiler:Melia's]] is not. Between this and the Royal Summoner class' ability to boost its damage each time an Elemental Discharge is performed, she's one of the very few Heroes that can do significant damage in her own right during a Chain Attack. Behold, [[https://www.youtube.com/watch?v=Z24o_JT2OzE a Level 1 party]] with [[spoiler:Melia]] taking down Levialord Empireo at Lv. 180 and using her abilities to achieve early and repeated "Amazing!" rankings during Chain Attacks.

* [[VideoGame/XenobladeChronicles2 Rex]] is the overall best character in ''VideoGame/XenobladeChronicles3FutureRedeemed'', having insane skills that rely on Critical Hits, just like Mythra. His skill "Raging Flame" increases damage by 8% every time you get a crit at max Affinity Growth, all the way to 150%, causing him to have a hefty amount of additive damage that racks up very quickly due to a lot of his attacks being multi-hits and Double Spinning Edge being incredibly spammable due to hitting multiple times and recharging after every CriticalHit. His other skill "Lightspeed Blade" increase critical hit damage from 25% to 75%, and ignores any enemy defence value if crit, which means enemies will take normal damage from his attacks even if they have high physical defence. His other skill "Heroic Spirit" is situational, but gives him a 150% increase in damage when allies are low on HP or knocked out, and allows him to take 30% less damage, mitigating his GlassCannon status, and his final Skill increases his Critical Hit Rate by 20 percentage points, and gives him 50% increase in critical damage. This allows him to nuke health bars in Chain Attacks and do even more damage then the party members in the regular game can do, and in addition when combining "Rolling Smash" with "Anchor Shot" using Ouoroboros Arts it allows him to do a Break and Topple on the same attack, and he can also launch with Dual Blast, giving him the only access to the full driver combo, as Smash can be used with Matthew's Union Strike.

** The Lifesage Hero, [[spoiler:Nia]], is considered to be among the best Heroes in the game behind Ashera and Fiona; she has the highest Healing stat in the game, and has abilities that make her useful during Chain Attacks. Her Chain Art is a guaranteed revive on all fallen party members; while it can be niche, it's invaluable in sticky situations, meaning that if worse comes to worse, you only need to focus on keeping said Hero alive so she can revive your allies during the Chain Attack, making it an excellent comeback/emergency tool. Her Heroic Chain is more versatile in most situations, re-activating ''all'' characters for the next round regardless of your TP score; while this is usually offset by her very low base TP of 15, this can be made up for by equipping her with the Veneris Rings, bumping her TP up to 35, and having her finish a Chain during a Healer's Chain Art (herself, Eunie or Taion) to get the extra role match TP, granting a very likely "Bravo!" and having ''every'' playable character available to use for the next round. Overall, having [[spoiler:Nia]] or a Lifesage party member is an absolute necessity for any postgame team that needs a dedicated healer, and drastically improves the team's odds of survival against extra-tough enemies.

* The Lapidarist class, while not quite good damage-wise as Fiora from ''VideoGame/XenobladeChronicles2'', focuses on dealing critical-hits and healing the party while doing so. The crux of its kit is Beaming Edge, increasing crit rate up to 20% and damage by up to 50 percentage points, which synergizes with Frenzied Combo and Eye for Weak Points to enable the broken Critical Recharge Strategy, supplemented by arts which come out very fast, hit multiple times, and come with healing effects on their own. It benefits greatly from being a Kevesian class, being able to set Master Arts from the better healer classes (which tend to be Agnian), and do a better job than most of them due to their Arts charging faster when canceled. With the optimal setup, it supplants Signifer as the best class in the game.

* By itself Taion's Interlink seems like nothing to write home about, as it is a debuff-based mirror of Eunie's when debuff-based characters are a TierInducedScrappy. At the same time, Taion's Eclipse skill makes his Interlink the only debuff-based character who has a reasonable chance of getting said debuffs to land. Better yet, link Eunie's Shared Blessing skill, and this can translate into his Interlink doing as much or even more damage than Eunie's, making it almost as powerful outside of lategame bosses.

* The Seraph class for Attackers is this game's interpretation of the standard high risk/high reward playstyle in [=RPGs=], except that in this case there's barely any risk. Their strongest Arts do self-damage, but only by 10% of ''current'' HP, making it highly unlikely for the Seraph to kill itself. More importantly, Seraphs have a Skill which grants them the extremely potent Awakening buff after taking a bit of damage; however the damage does not need to be done in one hit, and the self-damage does count toward triggering it so it'll have high uptime. Combine that with its Skills that provide massive damage buffs under easily-obtained conditions and you have a winner. Seraph's massive aggro-drawing capabilities can also be weaponized for dodge tanking in conjunction with the Protector's Pride/Fraternal Badge/Frenzied Combo setup since it has a Stance Art to combine Quickdraw with (allowing an evasion-based Talent Art like Shining Refrain to be charged up very quickly), though it's far riskier than the other attacker classes used for dodge tanking due to the Seraph's lack of an innate evasion Art.

* Eunie's Interlink form is uniquely overpowered due to her Shared Blessing Skill, which allows a damage increase for each buff on the party. With her Feather Sanctuary Art giving the party up to 6 random buffs per use, her damage ramps up much faster than the more damage-oriented Interlinks, with her Talent Art dealing tens of thousands of damage even at low levels. As a bonus, said buffs last longer, she passively deals auto-attack damage to every enemy in range, and if she does get hit, she has a chance to do a massive party heal. This can be made even more broken when combined with the Signifer Class, which in itself is also a GameBreaker and the best class in the game (see below) and makes Eunie/Taion's (if linked) Ouroboros order even more powerful.

* Anything that decreases or refreshes Art cooldowns, such as much of Troubadour's toolkit, Frenzied Combo (Martial Artist skill), and especially Protector's Pride (Guardian Commander skill) or the related Friendship/Fraternal Badge accessories can trivialize the game under the right conditions due to allowing hilariously short Arts cooldowns when stacked together. Frenzied Combo in conjunction with Attackers with a high Crit Rate and/or multi-hit attacks allows for Arts to fully recharge by the time their animation completes, while some team compositions that make use Protector's Pride and Fraternal Badges will actively avoid having Defenders, or only use them in support roles.

* For the most broken thing in the entire game, the Signifer class and Troubadour's Glittering Melody can also be combined with Noah's game-breaking Lucky Seven listed above in an exploit that allows Signifer to pass Noah's invincibility to the whole party and keep it active forever, meaning it becomes impossible to take any damage or debuffs for the rest of battle by having Noah activate his Talent Art, sheath and unsheath his weapon to have access to Resonant Flag, then pass his buff to everyone else while using Glittering Melody to keep it from expiring.
