This guide contains NUMEROUS unmarked spoilers about just about the entire game. Continue at own risk.

- In the Power Plant, every time a fae is freed power, and your passive income, is reduced by 50. Thus for best passive income, you want to hover each tube to ~95 mana for better passive income. Might be negligible or crucial depending on your goal, challenges, and NG+ or not.
- You need to have the Greedy Apple accessory equipped to upgrade the Time Pineapple in Jot's Shop.
- The Golden Goal options which are most useful are the critical boosts. As such, I recommend taking the free ale/10 products, Goalie Refund always trigger, +2 critical chance, and either Goalia Max triggers for all products or free wine/10 products, to activate the Goalorothy bonus of +3 crit from having three of their upgrades active.
- After getting Treva as a customer, but before unlocking the Loot Bags products, you can find a tiny Treva Doll behind the tavern, and give it to the upgrade guy with 60 gold to make Treva pay much more for floral hats (around ~150 coins?), but Treva dies eventually.
- If Divina heals the fake prince (by sensing royalty on him to make him a customer, then taking a photo of him during chain to unlock permits), the fog in the graveyard area becomes slightly less horrible.
- Behind the Craft workshop in Enterpriston, there is a secret room.
- At around ~100 Alcoholism the Barkeep allows you into the backroom in the Underwalk pub. At around ~450 Alcoholism he teaches you how to make manashine in the backroom. At around ~500 alcoholism he teaches you how to throw away alcohol to decrease alcoholism. Also at around 500 alcoholism, it seems that converting alcohol to mana begins getting a chance to possibly fail. At some point before manashine, high alcoholism also unlocks the option to drink until your mana is full.
- Vend, Mandy and I think Dobblebiz? can run your Enterpriston shop for you, the latter two only if they're not your clerk. Mandy is in the Enterpriston bureau if Tablebird is your clerk.
- Can buy the Unique Pendant randomly at the Auction
- At some point Tinto trades become self-sustaining, or near self-sustaining. My usual setup for Tinto trading: Dragon Avarice, Loaded Dice, Idol of Guilt, Four-Leaf Clover, Merchant's Cunning. For most items crits are more important than the extra income from animal magnetism gems, and it's not worth the effort to switch over for a few items.
- Magna's Battleaxe found in the level fungi unlock cave, in one of the jail cells. Key is under Two's part of the desk in the Bureau meeting room. Recommended to have the Boots of Haste equipped and the Life Insurance Policy before attempting to retrieve it.
- When you can buy Tax Evasion Credits, they go for a million coins, if that gives you idea of how much tax you should aim to evade with them.
- I've seen fishing minigame fish sizes ranging from 1-29kg. Upper end does seem to be around 29-30kg probably

In various places in Tutetown, Enterpriston and the Capital (but not Faeona), there are wilted, neglected or otherwise suffering potted plants, whose suffering Mabiz can prolong with the Wild Growth spell, earning her Generosity. Eight in total.

In various locations in Tutetown, Enterpriston and Faeona (but not the Capital) there are plants with lots of mana that Mab can absorb. This does four things. 1: kills the plant, 2: restores Mab's health and mana to full, 3: every four mana plants absorbed increases Mab's max mana and health by 1, 4: increases Mab's ruthlessness.

Discovering relics requires you to become a councillor in Faeona, pay off Faeona's debt to the bureau, buy the old palace, and then give Refrain a permit to gain the Relic Sight buff. When you're close to a relic, a big purple eye will pop up above it, to help you spot them.

At the west side of the Enterpriston Lake, interact with the obstacle to the lakehouse. Then talk to the barkeep in the Unerwalk Pub in Enterpriston. You have now unlocked the fishing minigame at the Lakehouse. Fish enough to get the third prize, a fishing pass which lets you activated and use the Barkeep's teleport nodes. Later, you can find out it was Odina that set these up. Sneaky! Each teleport costs 10 mana, except the Ruins Mapping Camp teleport, which costs 40.

Various spells and how to unlock them.

Fate Over: Mab starts the game with this. A purely narrative finisher to kill various people.
Final Profit: Title Drop! Mab learns this in the confrontation with Five. Seems to break shield gems and also do massive financial damage to the Life Insurance Policy? Possibly an evolution of Fate Over?

Former Glory: Odina spell. Gives angst?
Defy Dimension: Odina spell. Allows Odina to teleport. Unlocked with Enterpriston shop.
Siphon Mana; Allow Odina to take mana from volunteers. Unlocked with Enterpriston shop. Presumably what she uses when you sell her mana.
Borrowed Strength: Odina Spell. Specifics unknown

Wild Growth: Grows plants. Learnt in the apple labyrinth. Useful for accessing certain places and also growing assorted fruits.
Apple Slice: Spell from the Apple Labyrinth. Teleports you to the entrace of the Apple labyrinth. Right next to a barkeep node, a portal to the level cave, and close to an entrance to the horsecut, so very useful for getting around.
Wild Ascension: Found in the apple labyrinth. Allows Biz to lift heavy big black balls.

Sense Royalty: Talk to King Bean for the first time. Senses royalty, whatever that means.
Distill Wellness: Donate Health to the Owl Lich about ~3 times? Converts 1 Mana into 1 Health. Pretty useful for giving health to Owl Liches but not really beyond that.
Bestow Mana: Learned from Odina after buying the Enterpriston shop, to bestow mana on the Automation Pillars, also used to bestow mana on the big mana storage gem later, and for the Fae Power Tubes and the Deer Mana Plant.
Nature's Beckon: Grow assorted fruit to seeds several times to unlock? Matures fruit to seeds.
Faeonic Fishing: Mab remembers this spell when the Barkeep invites her to some friendly competitive fishing. Catch-and-release fishing without the "catch" part, just scanning the fish and telling your friends the one you caught was *this* big.
Fish Motivator: Fish several times, and Mab will grow frustrated and develop a spell to "convince" fish to move about so she can scan them.
Crunch: Unlocked by going on an expedition with the artist. Greatly speeds up the process of art creation through the application of mana.
Dimensional Shift: Bribe the Dimensional Officer that shows up when you ask Pixa to teleport the artist around a bunch. Then have pixa teleport the artist a bunch more until the Dimensional Officer shows up again and demands a fee of 5000 coins to clean up. Then go into the alley next to the shop, and talk to the Dimensional Officer in there to learn the Dimensional Shift spell. Allows you to move though customers in the shop. Only applies to customers on the screen when it's cast, so won't work on any new customers that enter. Note that you can't block the dimensional shifted taxman from getting to your vault!
Summon Replete: After completely filling up the large storage gem in your enterpriston shop, ask the witch if you're a dog or a cat person and she will teach you how to summon the mana dog to follow you around all the time.
Buyer's Market: Enter your office after becoming a Lord of Business to unlock. Allows you to buy real estate. You're a real rentier now!

Gem Polarity: Talk to Divina after completing the Power Gem deal with Faeona. There's a hidden entrance to the treetops to the right of the assembly benches thing. Reverses the polarity of gems, which only really does something to shield gems. But by the point you learn it, only the CEO is using a shield gem, so it's only used to unlock an ending.

There are three spellbinders, allowing you to bind a specific spell to a hotkey. Once you've talked to all three, they give you a portable spellbinder allowing you to bind a spell anywhere.

Personally, I tend to have Distill Wellness bound early on while I hatch all the Owl Lich eggs, and after that I switch to Apple Slice for the majority of the game for the convenience in transportation it gives. Very late game, I might temporarily switch to Dimensional Shift, when the Enterpriston shop is just absolutely clogged with customers and you need to get to the tribute mat or tea seller or vending machine or some such.

The secret customers and how to unlock them.

Mailnan: Choose to make post office stock more volatile (lowering envelope price, the the ruthless option) and then sell a thousand envelopes and the Mailnan becomes a customer.
Spirit Child: Talk to the mother outside the Underwalk Pub, find her son next to the Famine memorial give him a fruit of life, talk to the Owl Lich in the Apple Labyrinth, get starving ghost girl customer.
MassDRANK!: Buy the Vendrank bottling factory north of the power plant and buy ~six vending machine upgrades to make MassDRANK! appear outside the factory. Give him a Vendrank and he becomes a customer.
Patron: Buy the eastmost property in southeast Capital, enter it and talk to the Patron to unlock them as a customer.
Loot Goblin: Around the point you become a Lord of Business, the Loot Goblin will appear in the sewers near firebird, talk to them to unlock them as a 'customer'. They will steal items. If you manage to catch them they will give you back double what they steal. Useful for permit farming, but not idle-friendly. After you caught them a few times, you can hire the bouncer from the Underwalk Pub to bounce him for you.
Mimic: In the level-locked cave, unlock the level 90 fungi, and complete the ghost storyline to unlock Mimic as a customer. They seem to have a minigame where they jump behind your shop counter to ask for specific items which they pay for, but personally I just set them to buy permits instead.
Minappletaur: Unlocked from the 50 apple chest. Runs on top of your counter buying all the stuff?

Odina stored mana is useful if you're planning to/have to fight One. Odina mana is only useful up to 10 000, so don't save up more than that. If you want extra mana above the Odina mana, use the middle butterfly 5 cap ability which gives the Gem of Displaced Restoration. Around 20,000 mana overcharge total (so easiest would be 10,000 from Odina and 10,000 from the crystal), is enough to reduce One to 1 coin. Odina gets mana from

- Buying Floral hats
- Charging up Enterpriston Automation Pillars (so 90+80+70+60+50+40+30+20+10=450 mana)
- Using the Barkeep teleport nodes
- Selling Mana Directly to Odina west of the Craft House
- Charging the mana gem in your shop (5120 mana)

Since selling to Odina is disabled during the process of unlocking permits, you might want to sell some mana to her before doing that, if you're aiming for 10 000. I wouldn't sell more than ~2000 this way since the remaining 3000 will almost certainly be accumulated incidentally through floral hat buying and teleporting.

Results: If enough Dos and not too many Don'ts you can skip the One fight (which is very long even if you have enough money.) If you want to fight, but have too many Dos and not enough Don'ts, you can force a fight if you're Ruthless enough. Try equipping high ruthless items and getting some last ruthless from mana plants and petty theft if you're short.

If Two is alive, they will give One ~122 million, raising One from ~633 million to ~755 million.

In the Ever Rest Inn Cellar and Underwalk Pub backroom, there are barrels of ale you can drink from for +1 Mana and +1 Ruthlessness. If you regret it later you can refill them with ale to undo the Ruthless increase. The mana is probably only actually useful in Tutetown, but ruthlessness can be useful for certain story unlocks.

Ever Rest Inn Cellar, Four Ale Barrels

Underwalk Pub Backroom, Five Ale Barrels
Behind the Enterpriston MrTony's is a barrel you can steal 15 salt from which also increases Ruthlessness by 1. You can replace the salt to decrease Ruthlessness.

After you buy the extendo grabby hand thing from the electronics shop in Enterpriston (southwest of the Post Office), you can terrorise the wildlife for surprisingly valuable loot. Upgradeable in Jot's shop, but generally you only do this for the Lucky Clovers.

Woodway Warren
Castle Marx Warren
Faeona Entrance Warren
Faeona Forest Warren
Faeona Cave Warrens

These can be given to the Collector in his basement for cash. You can find the key to his basement in the Apple Labyrinth.

You need to try and trade the spoiled orange, which you can find in a log in the Woodway, for plant grower in the sewer, and then talk to the Farm Owner in Tutetown to get access to one of the mushrooms.

C50 To get to the 50 chest, continue north from 19 chest. You need to complete a defence minigame where you keep Orange Salesmen off Apple Custard. High Health capacity and boots of haste recommended. While it is possible to capture Salesmen in your infused mug, and buy them off, these each seem to have limited uses. I usually try to bounce off as many as I can manage with Wild Ascension, before resorting to infused mug and buyoffs. Once the Big Black Ball countdown gets to ~17, I've usually run out of uses of mug and buyoff, and just block one side of Apple Custard with my body, and she has enough health to last to the end.

I don't know if the missing number chests just don't exist or if I just didn't find them.

Need to have talked to one of the green accessory skeletons (first one shows up behind the Ever Rest Inn), before he shows up.

Sells you cursed accessories that you then have to pay the witch in the apartment building to decurse so you can use your accessory slot again.

The mug from him is required to capture Orange Salesmen.

First: Cafe in Enterpriston
Second: Gully north of where game starts
Third: Faeona Slums
Fourth: Capital northeast of museum
Fifth: Horsecut dimension, south of Tutetown Exit

After finding all 50 apples and completing the Apple Labyrinth, if you have the Mug accessory equipped, Granny Smith offers you a nice nest egg of 20 mil in exchange for catching 4 orange salesmen.

Tutetown, north of Farm Owner House, need to have tried to trade away the spoiled orange to plant grow seller in Enterpriston Sewer
Enterpriston near the Information Centre
Enterpriston, upstairs and at the back of your shop through the window. Might need to clean up dimensional gunk before you can get to him.
In the Capital just south of Mab's office.

Located midway into the Apple Labyrinth. Highly recommended to get the Life Insurance Policy and Boots of Haste before attempting. You need to collect 13 apples in the maze while staying away from the Minappletaur. Around apple 6, the Minappletaur is faster than Mab unhasted, even if autodashing.

If using the boots of haste, I press a dash hotkey near exits to go slower to easily move from layer to layer.

Gives 25,000 and unlocks the Mat of Tribute. Repeatable for the 25 000 coin reward, but not worth it unless you really enjoy the minigame.

Map

There are two balls (circled in green) that you can lift with Wild Ascension, and three shortcuts (marked in yellow) where you can jump over the wall (allowing you to move faster or potentially bypass/avoid the Minappletaur).

You need to buy an upgrade in Jot's shop before music track chests become visible. Some chests have further unlock conditions before they become visible.

Exhausted
Turn back to Faeona once you get exhausted at the beginning of the game. All this walking is hard work!
Stagnation
Don't have enough money to buy the Enterpriston shop on your own (15-30k coins), and decline a loan.
Phoenix
Cold turkey table bird. He will set your shop on fire around the point you get battlepass candles. Just wait out the timer.
Insolvent
Have your loan debt reach 200 000. Takes a long time.
Don't Look
Look at the first blackmail Birumue gives you.

Thank you for people answering a bunch of my questions on the Discord. While I'll probably miss some, Magentawolf, EDL666, crazycrash115, Brent and Grub were very helpful.
