History GameBreaker / Persona

** With the release of ''Royal'' on the other current gen platforms, all of the DLC is free, adding the likes of Izanagi-no-Okami and Raoul mentioned below to the Persona compendium for maximum breakage. Accessories-wise, the Camera Strap (formerly from the Persona Q2 costume DLC) fulfills almost the same role as the SP Adhesive, only marginally better, providing a ''10% heal and 10 SP per turn'' when enemies are ambushed (easy to do consistently with enough practice). This effectively trivializes SP management and removes the need to get SP Adhesives in the first place, beyond boss fights (remedied by stockpiling SP items). The fact that it is available even earlier than the Velvet Room Personas and way before SP Adhesives can even be bought is icing on the cake.

*** This Trait works incredibly well with Yoshitsune which turns the already powerful Persona into an unstoppable force. Very few Persona can stop an Apt Pupil Charged Yoshitsune's Hassou Tobi with the 'Will of the Sword' or 'Undying Fury' Traits.

* Gozu-Tennoh/[[DubNameChange Vortek]]. A [[GlassCannon Chariot Arcana]] starting with only Squash and Poison Sting, it's not able to attack well except when it ranks up to 3 when it learns ''[[ILoveNuclearPower Me]][[DiscOneNuke gi]][[TotalPartyKill do]]'', as long as the enemy doesn't [[NoSell block or reflect Nuclear]] it's not hard to wipe the entire enemy. Keep using him and he learns ''Megidola'', the 2nd tier in [[NonElemental Almighty]]. Slap it on to [[CantCatchUp Mark]] and it's possible to have him surpass the party in levels. When he max ranks and is too frail to continue, return him and you get a [[GravityMaster Grydyne Stone]].

* Even more game-breaking than the Fox and Ask for Help is Rise's unlockable ability to replenish the Investigation Team's SP and HP after every battle; it may be a small amount, but the healing after repeated battles can keep your team in a dungeon for hours without needing much, if any, healing at all. It also helps make the Fox somewhat obsolete or, at the very least, makes his services much more affordable when needed (since the price of the Fox goes up the more SP that he heals).

* Physically-oriented characters like Kanji, Chie, Aigis, Shinjiro, and Akihiko are highly valued because of the fact that most of their abilities are CastFromHitPoints which are easily replenished, both thanks to Fuuka's healing and the HP/SP buffer given by Sub-Personas that's replenished after every battle. One of the most popular strategies involves equipping one of these characters with a Sub-Persona that has several of the various "Link" skills equipped, which allow them to add bonus elemental damage to every allied attack that comes after them. Kanji is a popular choice for this, as he has the highest natural strength score and naturally learns abilities that allow him to go first in battle, allowing him to maximize link damage. Junpei has less Strength, but has the Golden Gemini skill upon getting his ultimate Persona, which gives him a ''very'' high chance of executing ''any'' physical skill twice in a row (and the second is free). This includes Hassou Tobi.

* Combine Immunity Buffer with Life Wall and you have a tank who negates most physical attacks they're intercepting. Use it on Aigis, who can negate elemental damage, and you have a very resilient unit. You can even give Immunity Buffer to Aigis via Skill Card so that she can tank effectively without a specialized Sub-Persona. The combination is also viable in ''PQ2'' as Immunity Buffer can be inherited through fusion in that game.

* One-Shot Kill is an attack that does severe Gun damage and has a high chance to crit, but without the reduced-accuracy drawback. Trigger Happy and Apt Pupil will bump up its critical rate to nearly 100% and you can combine that with Snipe and Cripple, which increase damage from Gun skills by 25% and 50% respectively, letting the skill hit much harder than Miracle Punch can ever hope to get (there are no physical-boosting passives in the game). As long as the target doesn't repel or nullify gun damage, knocking down entire teams is absurdly easy. And you can combine that even further with Charge, increasing the damage by 250% next turn.
* The DLC Personas in general can fall under under this with a touch of BribingYourWayToVictory. Even among them however, a few stand out in terms of gamebreaking goodness.
** Izanagi Picaro comes with some of the best support passives in the entire game, at an incredibly low level for their value. He learns Null Phys at level 25 and Growth 3 at level 28. Once Izanagi Picaro gets these, you can pass them around to any Persona of your choosing, meaning by mid-game you can have a team of NighInvulnerable Persona you don't even have to ''use'' to unlock ''their'' skills. His SecretArt Cross Slash isn't half bad either, dealing the equivalent of two highly accurate Assault Dives to a single target.

* [[spoiler: Satanael]] is by far the most insane Ultimate Persona yet. It resists every single element in the game, [[NoSell is naturally immune to both elements]] that have OneHitKill attacks, learns powerful Curse, Nuclear, Gun and Almighty skills, is the only Persona in the game who learns Victory Cry and has fairly high stats across the board. However, you can only fuse it on NewGamePlus after reaching the GoldenEnding and can only access it at level 95 (unless you have maxed out the Strength confidant), by which point the only thing you'll likely need it for is probably the BonusBoss; the Persona then becomes a BraggingRightsReward afterwards.

* The new "Third Tier" Personas for the Phantom Thieves each come with unique skills that make the third semester a joke, even turning the dreaded Reaper into a pushover. It really makes the payoff for maxing the party members' Social Links very worthwhile:

* Even more game-breaking than the Fox and Ask for Help is Rise's unlockable ability to replenish the Investigation Team's SP and HP after every battle; it may be a small amount, but the healing after repeated battles can keep your team in a dungeon for hours without needing much, if any, healing at all. It also helps make the Fox somewhat obsolete or, at the very least, makes his services much more affordable when needed (since the price of the Fox goes up the more SP that he heals),

** The Crystal of Vanity starts with a passive ability to remove all persona weaknesses just by wearing it, which is incredible for anyone but especially Joker. It's difficult to overstate just ''how'' insane this is. It completely negates the need for Resist/Null/Repel/Absorb Element skills, which are often considered by Megaten veterans to be game-breakers in their own right, and whose primary utility is actually ''not'' to bestow the resistance/immunity as one might assume but to cancel out your Persona's weaknesses. But the Crystal of Vanity means you don't need to bother with any of that. Just slap it on and it cancels out ''every single one'' of Joker's weaknesses, meaning you can use your skill slots for other things. After upgrading to the Ring of Vanity it gains Bleeding Dry Brush, letting you cast a single target barrier spell that absorbs non-Almighty damage, making it great for both plugging key weaknesses in a pinch and keeping a party member alive.

* [[DangerousForbiddenTechnique Shura Tensei]], a buff skill that returns from the previous ''Persona Q'' game, remains incredibly broken. At the cost of half of a character's maximum natural HP after each attack (which can easily be recovered with Navi skills), their damage output is ''tripled''. Like before, Shura Tensei lasts indefinitely and doesn't use a buff slot, so you can stack more skills like Power Charge, Heat Riser, and Dragon Cry to make the most of it. Firing off Links or boosted physical attacks, in this state all but guarantees a win against the majority of enemies and [=FOEs=] in the game. It's disliked among many players because of how extreme the move is, both in risk and reward.

* The Persona with the highest base level is not Lucifer, but Huang Di. His innate skills are simply crazy -- Fury Order and Focus Order are Power Charge and Mind Charge respectively but they apply for the ''entire team'' instead of just the user. Empyrean Storm is a PercentDamageAttack that wipes out 20% of its victims' remaining health, which can dramatically shorten FOE and boss fights. You get the key item to unlock his special fusion by fully mapping out the penultimate floor. However, his base level is 89, so by the time you can fuse him, [[BraggingRightsReward you've likely got access to more optimized builds and won't need him]].

** The Crystal of Vanity starts with a passive ability to remove all persona weaknesses just by wearing it, which is incredible for anyone but especially Joker, who now doesn't need to worry about his many Persona weaknesses for most of the game. After upgrading to the Ring of Vanity it gains Bleeding Dry Brush, letting you cast a single target barrier spell that absorbs non-Almighty damage, making it great for both plugging key weaknesses in a pinch and keeping a party member alive.

** Vitality of the Tree (Attis) allows free use of skills that can normally only be used when surrounded. The ability to use Thermopylae (which Attis will start with) at any time alone makes this extremely powerful, and keeping all stats buffed a breeze.

* Gozu-Tennoh/[[DubNameChange Vortek]]. A [[GlassCannon Chariot Arcana]] starting with only Squash and Poison Sting, it's not able to attack well except when it ranks up to 3 when it learns ''[[ILoveNuclearPower Me]][[DiscOneNuke gi]][[TotalPartyKill do]]'', as long as the enemy doesn't [[NoSell block or reflect Nuclear]] it's not hard to wipe the entire enemy. Keep using him and he learns ''[[UpToEleven Megidola]]'', the 2nd tier in [[NonElemental Almighty]]. Slap it on to [[CantCatchUp Mark]] and it's possible to have him surpass the party in levels. When he max ranks and is too frail to continue, return him and you get a [[GravityMaster Grydyne Stone]].

*** This Trait works incredibly well with Yoshitsune which turns the already powerful Persona [[UpToEleven into an unstoppable force]]. Very few Persona can stop an Apt Pupil Charged Yoshitsune's Hassou Tobi with the 'Will of the Sword' or 'Undying Fury' Traits.

** Satanael has been [[UpToEleven made even stronger]] with the trait Pagan Allure. This innate trait functions as an 50% boost for all magic damage, which stacks with boost/amp skills and gives Satanael an attack power to match his near-impenetrable defense. Combine this with his new passive skill, Tyrant’s Mind (further boosts his damage output and breaks the boosting cap), and Satanael can easily output more damage than any non-DLC Persona in the game.

* ''[[UpToEleven Speaking of which.]]'' Izanagi-no-Okami and Izanagi-no-Okami Picaro, from a separate DLC pack, quickly gained infamy as an absurdly powerful Persona, even compared to Yoshitsune and Kaguya. Myriad Truths returns, dealing three hits of Heavy Almighty Damage to all foes, making it the strongest Almighty attack in the game. In short, it will obliterate virtually anything you point it at short of a boss, and after being backed up by a Concentrate boost and hitting the boss with Debilitate, entire phases can be taken down in one attack. While it costs 40 SP to cast, Okami can refund it after battle thanks to the Victory Cry skill he ''starts with''. Okami naturally resists all elements except Light and Dark, making it trivially easy to fuse him into NighInvulnerability (especially with the St. Hermelin's Badge, an equip that Nulls Bless/Curse, effectively removing his only elemental vulnerabilities AND any potential instakill from Hama or Mudo skills). Finally, Okami's [[MagikarpPower Country Maker]] trait raises attack and defense based on the number of Personas registered. Players with near or complete Persona Compendiums will truly feel like a God among men using this Persona. In addition, he provides some useful goods when itemized: the regular version yields the Shining Headband, which adds 2-3 points to each stat as well as Invigorate 3, making it a strictly better SP Adhesive. The Picaro variant gives you a Mediarahan (full HP to all allies) skill card normally, and Salvation (the same, but also removes status effects) under a Fusion Alarm, making surviving boss fights trivially easy.

*** This Trait works incredibly well with Yoshitsune which turns the already powerful Persona [[UpToEleven into an unstoppable force]]. Very few Persona can stop an Apt Pupil Charged Yoshitsune's Hassou Tobi with the 'Will of the Sword' Trait.

* Similar to Trumpeter, Beelzebub has four immunities, so you'll only need three immunity passives to make it invulnerable to everything barring Almighty attacks.

* The ultimate persona of the Star Arcana; Lucifer (Helel in the [[UpdatedReRelease FES and Portable remakes]]). His stats are sky high, his resistances are decent, and learns Morning Star, which deals even more Almighty damage than Megidolaon with less SP. However, those are almost moot provided the player also has Satan; the "Armageddon" Fusion Spell, which deals 9999 Almighty damage to all enemies at 100% accuracy. While it ''will'' kill every enemy who isn't the FinalBoss or the [[BonusBoss Ultimate Boss]] in the game, Armageddon in itself isn't a GameBreaker, because it costs 100% of your MP to cast. No, what makes it this trope is the passive skill "Victory Cry" which replenishes all your HP and MP at the end of each combat (Lucifer learns it innately in the original game, but for Helel in the remakes it needs to be fused/equipped into). End result: You win everything. To top it off, it's fairly easy to fuse him with the aforementioned "Spell Master" which halves all MP cost. Yes, that includes Armageddon. Now, even going into combat in less than 100% SP lets you win everything as well. However, in ''Portable'', Fusion Spells are done via items which require grinding for more items (and Armageddon requires ''99'' of the main item and 10 more difficult ones to get).

* ''FES'' also brings the MC's ultimate persona: Orpheus Telos. This palette swap of your original persona is clearly specifically designed for the BonusBoss because it resists everything but Almighty and Poison (the BonusBoss will automatically kill you if your persona absorbs or repels any of her attacks, so resist is the best possible option) and has great stats. The only spell that it learns naturally is Victory Cry, but most importantly, it can inherit ''every skill in the game''. If you plan everything out right, you can have a single persona with the eight best attacks in the game. Mix and match to your heart's content to decide what eight skill combination is right for you. The catch? He can inherit '''every''' skill in the game, not just the best ones, and because he has an equal likelihood to inherit every skill, you'll spend hours wading through combinations with inferior skills, hoping for that one-in-a-million perfect combination that you just spent a few hours setting up. Of course, this is all assuming that you maxed out every social link in the game, have the necessary fusion fodders, and are above level 90; the requirements for being able to fuse Orpheus Telos.

* Trumpeter starts off immune to Dark, reflecting Light and Electricity, and absorbing Ice. As a Hexagon fusion, it is moderately easy to get the other three immunities, giving you a Persona immune to everything except Almighty and Poison. On top of that, Trumpeter gets the best buff and debuff spells and the strongest non-unique Almighty spell automatically. And you can get Spell Master on it for spamming Megidolaons all day (use Skadi to fuse Daisoujou, one of the components for Trumpeter). Unlike most other game breaker Personas in the game, which require some dedicated grinding, Trumpeter is fuseable at about the level you'll either naturally be or are recommended to grind to (depending on difficulty-based EXP gains) before the final run of the Normal ending.

** The Ring of Sorrow grants a skill that only does minimal damage but is guaranteed to knock down all enemies. The attack is Almighty-elemental, meaning nothing in the entire game can resist it or avoid it (unlike Miracle Punch). [[labelnote:note]]Take note that the closest equivalent of this attack is used by the [[BonusBoss Velvet Room Assistants]] when you fail their threshold and this skill is a {{Nerf}} in comparison to ones used in their fights.[[/labelnote]]The caveats are that you can only use it if you start an encounter by ambushing the enemy, and it is unobtainable on a New Game as Jose cannot upgrade the Crystal until after the FinalBoss, by which point Mementos can no longer be visited. But it's extremely useful in NewGamePlus, allowing you to trivialize random encounters with a first-turn All-Out Attack or negotiation. That isn't to say that the Crystal of Sorrow isn't bad by itself, as it gives the Life Aid skill, which restores 8% of the wearer's HP and SP after each battle.

** There are unique skills for [[MissionControl Fut]][[SupportPartyMember aba]] on the original cocktail depending on how many times you visit. By the third visit she gains Support Boost 3 which gives a chance to trigger Masukunda, Marakunda, or Matarunda, and by the fourth visit, she gains Support Chance Up which activates Moral Support more frequently. Futaba would become a support powerhouse even before going into her "Third Tier" Persona mentioned below.

* ''[[UpToEleven Speaking of which.]]'' Izanagi-no-Okami and Izanagi-no-Okami Picaro, from a separate DLC pack, quickly gained infamy as an absurdly powerful Persona, even compared to Yoshitsune and Kaguya. Myriad Truths returns, dealing three hits of Heavy Almighty Damage to all foes, making it the strongest Almighty attack in the game. In short, it will obliterate virtually anything you point it at short of a boss, and after being backed up by a Concentrate boost and hitting the boss with Debilitate, entire phases can be taken down in one attack. While it costs 40 SP to cast, Okami can refund it after battle thanks to the Victory Cry skill he ''starts with''. Okami naturally resists all elements except Light and Dark, making it trivially easy to fuse him into NighInvulnerability. Finally, Okami's [[MagikarpPower Country Maker]] trait raises attack and defense based on the number of Personas registered.

In addition, he provides some useful goods when itemized: the regular version yields the Shining Headband, which adds 2-3 points to each stat as well as Invigorate 3, making it a strictly better SP Adhesive. The Picaro variant gives you a Mediarahan (full HP to all allies) skill card normally, and Salvation (the same, but also removes status effects) under a Fusion Alarm, making surviving boss fights trivially easy.

** The Ring of Greed and Ring of Pride allows the holder allows to cast an upgraded version of Concentrate and Charge respectively. In this case, instead of being limited to casting it on themselves, they can choose ''anyone'' in the active party to give the effect. In addition, they also grant Attack Master and Defense Master passives respectively. These accesories are particularly usefull for party members like Haru, Kasumi and Akechi who otherwise join the party too late to gain Concetrate or Charge from the Jazz Club.
** The Ring of Sorrow grants a skill which only does minimal damage but is guaranteed to knock down all enemies.

That isn't to say that the Crystal of Sorrow isn't bad by itself, as it gives the Life Aid skill, which restores 8% of the wearer's HP and SP after each battle.
* Status effects have received a significant buff in this game, while the Technical mechanic was overhauled to be much more effective with investment: playing Billiards enough times makes Technical Attacks far more powerful and guarantee a knockdown. With the special book from Jinbocho, you can also unlock more status-element combinations that grant Technicals. The game even recommends statuses and technicals as the main strategy against the enemies with no weaknesses.

** And lastly, there's Country Maker (Izanagi-no-Okami/Izanagi-no-Okami Picaro), which boosts Attack and Defense based on how full the Persona Compendium is. This trait is a large factor in how Izanagi-no-Okami breaks the game so hard (see below), especially when combined with its signature three-hit Almighty Attack Myriad Truths.
* ''[[UpToEleven Speaking of which.]]'' Izanagi-no-Okami and Izanagi-no-Okami Picaro, from a separate DLC pack, quickly gained infamy as an absurdly powerful Persona, even compared to Yoshitsune and Kaguya. Myriad Truths returns, dealing three hits of Heavy Almighty Damage to all foes, making it the strongest Almighty attack in the game.

As a Hexagon fusion, it is moderately easy to get the other three immunities, giving you a Persona immune to everything except Almighty and Poison. On top of that, Trumpeter gets the best buff and debuff spells and the strongest non-unique Almighty spell automatically. And you can get Spell Master on it for spamming Megidolaons all day (use Skadi to fuse Daisoujou, one of the components for Trumpeter). Unlike Lucifer and Yoshitsune, which require some dedicated grinding, Trumpeter is fuseable at about the level you'll either naturally be or are recommended to grind to (depending on difficulty-based EXP gains) before the final run of the Normal ending.

* Lucifer makes his return as the notoriously hard-to-fuse but gloriously broken ultimate Persona of the Judgement Arcana. He learns ''both'' Victory Cry and Spell Master naturally, and given his fusion requirements can already pass him very powerful offensive skills such as Megidolaon and Morning Star, he will tear up Shadows like nobody's business and completely recover by the end of every battle.

[[folder:Persona Q: Shadows of the Labyrinth]]

* Luck plays a massive role in this game, with Naoto being one of the most broken party members due to naturally learning ''both'' multi-target variations of the series' signature instant death spells. She also has high enough agility to ensure she can strike first, with Ken being not far behind in that category, and she has no elemental weaknesses to boot. And though Teddie's a bit of a TierInducedScrappy in this game, he has the highest luck score out of everyone, and can also be exploited for instant death. All three of them are also good contenders for StandardStatusEffects, ''also'' affected by luck, and unlike the main ''Persona'' games, are far more deadly and far more likely to work on bosses! Add to that the fact that sub-persona have their own SP values which replenish after fights. Once you get one with at least as much SP as your instant-kill move, you have free agency to use one at the start of every battle to thin the enemy numbers with nearly no cost.

* Auto-Mataru is a BoringButPractical game-breaker. If your character's equipped persona has this at the start of a battle, all your allies' offense increases, which can help you kill non-boss Shadows before they even get attacks off.
* The ultimate persona of the Emperor Arcana; Odin. His signature move Thunder Reign is the best of the 4 top tier elemental spells in the game because, in addition to the damage, it has 100% chance of inflicting the Shock ailment, which gives you 100% crit rate against the affected target with physical attacks. It's easily possible to defeat [[BonusBoss The Reaper]] as soon as Odin learns Thunder Reign in both the original ''Persona 3'' and in ''FES'' by stunlocking him with alternated All-Out Attacks and passing turns (this doesn't work as well in ''Portable'' remake, but you can still cause Dizzy on him, making him act only once every 2 turns). Odin also learns Elec Amp (+50% Elec damage) and Spell Master (reduces SP cost of all spells by 50%). It's extremely easy to pass Elec Boost (+25% Elec damage, stacks with Elec Amp) to him. His only problem is the weakness to Wind, but that can be fixed by passing Null Wind to him, or using equipment to give you that resistance.

* Norn innately learns Auto-Masuku, and with enough planning you can find and pass on Auto-Maraku and Auto-Mataru through her fusion ingredients. Having all three {{Status Buff}}s on ''your entire party'' at the beginning of a fight is pretty good so that you can do a lot of damage right off the bat. If you can also get her Null/Repel Elec and level her up till she gets Debilitate, you pretty much have a good starting Persona for boss fights.

*** Chihaya's Rank 7 ability is the use of the shrine without wasting time; you can significantly speed up bonding with your teammates with none of the time wasted. Play your cards correctly and you can eliminate holdover periods, like with Sojiro's notoriously slow Confidant.

* Lucky Punch and Miracle Punch don't do much damage, but they're relatively cheap and have a higher than usual chance of getting a Critical Hit. This is quite useful for knocking down enemies without any weaknesses, or for starting a Baton Pass.
** Similar to the above skills, One-Shot Kill is an attack that does severe Gun damage and has a high chance to crit, but without the reduced-accuracy drawback. Trigger Happy and Apt Pupil will bump up its critical rate to nearly 100% and you can combine that with Snipe and Cripple, which increase damage from Gun skills by 25% and 50% respectively, letting the skill hit much harder than Miracle Punch can ever hope to get (there are no physical-boosting passives in the game). As long as the target doesn't repel or nullify gun damage, knocking down entire teams is absurdly easy. And you can combine that even further with Charge, increasing the damage by 250% next turn.

** Izanagi Picaro comes with some of the best support passives in the entire game, at an incredibly low level for their value. He learns Null Phys at level 25 and Growth 3 at level 28. Once Izanagi Picaro get these, you can pass them around to any Persona of your choosing, meaning by mid-game you can have a team of NighInvulnerable Persona you don't even have to ''use'' to unlock ''their'' skills. His SecretArt Cross Slash isn't half bad either, dealing the equivalent of two highly accurate Assault Dives to a single target.

* The Persona Rangda can render the battle arena in [[spoiler:Sae's Palace]] a mere joke. It just so happens that Rangda can be obtained in the same palace. By having Rangda equipped you can easily defeat all three opponents. The Ganesha duo is only capable of using physical attacks so you can either play the entire fight in Rush Mode or guard the entire battle and win without doing anything. All three members of the Rangda trio have low HP and only use attacks which they themselves nullify, so having Rangda active gives you time to use restorative items if needed. And while Thor can take advantage of Rangda's weakness, his primary tactic is to use charge and then a powerful physical move, and having Rangda reflect it will cause his HP to severely drop. If that doesn't kill him, it should leave him weak enough that you can swap to another Persona to finish the job.

* The once [[ScrappyMechanic hated]] Insta-Kill now awards experience and money on use. While it only works on enemies a good number of levels lower, avoiding going into battle drastically lowers the amount of time it takes to accumulate a good amount of money and levels. It even receives the boost from money reading and Jose, making it unquestionably even more effective than confusing bosses (especially since the latter method got nerfed). It only activates while dashing and enemies weak enough to be killed by it will have a green outline if viewed through the Third Eye, so the player can clearly see when it will work and only activate it when intending to do so. Best of all, insta-killed enemies still count as battles, meaning that they build up to more alarms in the Velvet Room at no cost.
** Keep in mind, since Insta-Kill now only activates when you're dashing (And thanks to Rank 4 of Chariot, that also means enemies will find it harder to notice Joker while he's dashing.), if you still want to grind enemies that can give out lots of money or have a rare item you want through a hold up, you can do so without any risk of the enemy getting a attack in or you being so high leveled that Insta-Kill kicks in.

* The normally-hated Mementos becomes this in ''Royal'' thanks to new merchant character, Jose. If the player takes the time to collect flowers and stamps while exploring, they can eventually turn them in to Jose in exchange for rare items (flowers) and modifications to Mementos itself (stamps). With enough stamps, Jose can increase money, item, and/or experience rewards for Mementos missions. These modifications can be swapped at will and can drastically improve the rewards gained in the area. Combined with Ryuji’s Insta-Kill on and a bit of running down Shadows in safer areas leads to a massive profit.
