Guide for the Zub-less Unterzee Merchant

A guide on how to successfully conduct profitable trading in the Unterzee (for those without a Zubmariner). Consists of a list of different trading methods and routes. Part of the Guide for the Unterzee Merchant by warnor.

For the Zub-less

This guide is identical to the Guide for the Unterzee Merchant less the parts that requires a Zubmarine. It is tailored to those that have not acquired (or yet to acquire) what's necessary for commandeering a Zubmarine. If you do have a Zubmarine, I suggest using the original guide.

The Costs of Zailing

An important note before reading this guide: The costs of zailing (i.e. fuel and supplies) are not taken into account when calculating profits as they vary greatly with distances, routes, engines, crew etc. If you wish to do a profitable endeavour, you must make sure to have a lot of cargo space and capital to make big hauls. Additionally, you must carefully consider which trade methods and routes are the most profitable in your case depending on isle composition and your current circumstances. And remember to collect port reports to alleviate zailing costs.

In addition, the trade methods and routes in this guide can also be used to alleviate zailing costs or potentially make a profit while you are visiting ports for objectives such as an Admiralty Commission or progressing an Officer's story.

Cargo Jobs

“Trade methods” or rather jobs that require hauling certain types of cargo with zero capital requirements as you do not acquire them through purchase, but rather pick it up or harvest it. Useful for zee-captains low on Echoes or for making a quick Echo.

The Scintillack Harvest

The profit of this method can vary and is somewhat limited due to SAY. You zail to the Principles of Coral with the "Something Awaits You" condition in tow. At the Principles of Coral you can look for Scintillack which requires Mirrors (but still gives you Scintillack even if you fail). You will then receive 1-3 Scintillack which can be sold at Fallen London for 70 Echoes profit per piece. If you have or is able to get the House of Pleasure at the Iron Republic, you can sell the Scintillack for a profit of 74 Echoes per piece there.However, if you've won the final game in the Principality storylet, failing the Mirrors challenge will yield no Scintillack, and succeeding the challenge will always only yield 1 Scintillack. This greatly diminishes the possiblity of a lucrative venture, though still poses an opportunity to earn a little extra if you're at the Principles of Coral anyway.

The Clay Man Haul

Requires some zailing, is slightly hazardous and profit is very limited per run. Simply pick up Clay Men at Polythreme and deliver them to Fallen London with a 20 Echoes profit per Clay Man delivered. The limitation comes from the fact that you can only haul 6 Clay Men at a time, meaning you can always only make 120 Echoes in maximum profit per run. Hazard can be minimized by investing in a Secure Compartment (though that requires a free Aft slot).

The Ferry Job

Very limited per run and, depending on isle composition, can take some zailing. At the Mangrove College you can pick up a passenger which will either be A Shady Sort that needs to be taken to Gaider’s Mourn for a 120 Echoes fee or A Chequered Character that needs to be taken to the the Principles of Coral for a 100 Echoes fee. Same with the Clay Man Haul, it's very limited in max. profit per run as you can only carry one passenger at a time.

Basic Trading

Trade methods with short-to-medium distances, fairly low requirements for capital (except for The Sphinxstone Haul) and marginal or acceptable profits.

The Wine Trade

The easiest and least lucrative trade method is to stock up on Casks of Mushroom Wine at Fallen London and plot a course that goes through either Gaider’s Mourn, Venderbight, Khan’s Shadow or the Carnelian Coast. All these will bring in a profit of 2 Echoes per cask. Do not trade Firkins of Prisoner’s Honey at Gaider’s Mourn as it brings only 1 Echo in profit per firkin. If you have a Nephrite Ring you can also sell the wine at Khan’s Heart for a profit of 3 Echoes per cask. Similarly, you can earn a profit of 3 Echoes per cask by zailing to Adam’s Way and sell it there, but that takes a lot of zailing. In most cases, it is to be preferred to combine this method with another trade method (see Trade-routes). NB: If you wish to do more than just trade at Adam’s Way, remember to bring either news from London, a port report from Mount Palmerston or an Unfinished Log.

The Soul Trade

A rather simple trade method, but can take some zailing depending on isle composition; zail to Khan’s Shadow and stock up on Crates of Human Souls and then head back to Fallen London. You can then sell it at the Wolfstack Exchange for a profit of 3 Echoes per crate. If you have access to the Brass Embassy, you can also sell it to the devils for a profit of 6 Echoes per crate. That is if you have no quarrels with selling human souls to devils or enduring the repeated process of selling 1 crate at a time through dialogue.

The Coffee Trade

A fairly lucrative method, but does include long distances and/or special requirements. It requires visiting the Carnelian Coast, Adam’s Way, Iron Republic (requires House of Milks) or Khan’s Heart (requires Nephrite Ring and costs 2 more Echoes per piece). You purchase Sacks of Darkdrop Coffee Beans then zail to Fallen London to sell it for a profit of 4-6 Echoes per sack.

The Sphinxstone Haul

This will require some capital (roughly 200 Echoes) as well as 20 free cargo space, otherwise it’s fairly easy considering short distance and lucrative profit. You zail to the Salt Lions and fetch some Sphinxstone (which will require that 200 Echoes in deposit). Then you deliver it to Fallen London for a reward of 500 Echoes.The major downside to this is the limited amount of runs you can do as sooner or later the Ministry of Public Decency will lose interest in the stones, yet you'll have one more shot at making a profit from them.

The Pirate-monks Trade

A basic trade method that is a tad unusual compared to the rest. At Fallen London you stock up on Casks of Mushroom Wine. Make sure that the number of casks you end up when leaving London can be divided by 5 and result in no decimals. You can then sell the wine in bundles of 5 casks at Godfall for a profit of 9 Echoes per cask.However, after a certain amount of time in the Neath, the pirate-monks will pay less for the wine, bringing a negative profit of -1 Echo per cask. This happens when the condition "Another Day: Time, the Healer" reaches 200. Before "Another Day: Time the Healer" reaches 200, this is much more lucrative than the regular wine trade method mentioned above, but after it does reach 200, you will have to sell the wine through more conventional means. Or exploit other trade methods.

Intermediate Trading

Trade methods with varyingly long distances and capital requirements. They are either lucrative or merely convenient for an already-set course depending on isle composition.

The Devilbone Trade

A trade method with a route through Mt. Palmerston and Khan's Shadow. If the isle composition has placed the two relatively close to one another, then it's usually a useful trade method. If not, then there're probably better alternatives. You purcase Devilbone Dice at Mt. Palmerston and sell it at Khan's Shadow for a profit of 3 Echoes per piece.

The Ivory Trade

This requires a route through Khan’s Shadow or the Chelonate, and Polythreme, which can take some zailing, but is somewhat lucrative. Purchase Stygian Ivory at Khan’s Shadow or the Chelonate (cheaper by 1 Echo per piece) and sell it at Polythreme with a profit of 3-4 Echoes per piece. If you're heading straight to Fallen London, you can also sell the ivory there, which will yield a profit of 2 Echoes per piece if you got the ivory from the Chelonate. If you're heading straight to Fallen London from Khan's Shadow, it is unadvised to trade in Stygian Ivory, as The Soul Trade mentioned above will yield a higher profit of 2-5 more Echoes per piece.

The Linen Trade

The problem with this one is that the markets of the Iron Republic are not static thus the opportunity of this trade is random. But if you do have or get the House of Pleasures at the Iron Republic, you can purchase Bales of Parabola-Linen and sell it at Fallen London (3 Echoes profit per linen) or at Adam’s Way (6 Echoes profit per linen). The former is a much shorter, while the latter is more profitable. NB: If you wish to do more than just trade at Adam’s Way, remember to bring either news from London, a port report from Mount Palmerston or an Unfinished Log.

The Literature Trade

Not particularly lucrative compared to the trade methods listed above as well as requires access to the Nephrite Quarters at Khan’s Heart, but in case the opportunity arises, it is still a profitable business. At Khan’s Heart you purchase Romantic Literature in bulk and then zail to either the Carnelian Coast or the Iron Republic to sell it for 3 Echoes per piece. The Carnelian Coast is usually to be preferred (unless you already have the House of Pleasures), as selling at the Iron Republic will require the market to be the House of Pleasures, but has same sell value. Selling Romantic Literature is never lucrative at Fallen London as you will have to pay the Revenue Men to have it approved and thus make it sell-able which brings a negative profit of -2 Echoes per piece.

The Candle Trade

This is only advisable if your route goes to Venderbight from Khan’s Heart or Adam’s Way without passing through/by Fallen London. At Khan’s Heart (with a Nephrite Ring) and Adam’s Way you can purchase Foxfire Candles and sell them at Venderbight for a 3 Echoes profit per candle. But if your route does go through/by Fallen London, I suggest exploiting The Coffee Trade explained above instead as it brings a higher profit and might have a shorter route.

The Supplies-Republic Trade

Requires the House of Milks to be present at the Iron Republic, yet is fairly profitable. Purchase Supplies at Mount Palmerston, Fallen London or the Carnelian Coast. The two latter are cheaper and closer (the Carnelian Coast being the cheapest) and are thus more apt options. You then zail to the Iron Republic and sell the Supplies for a 3-7 Echoes profit per crate. Remember to leave some supplies for yourself!

The Supplies-Abbey Trade

There are usually better alternatives depending on isle composition, but in case the opportunity arises: If your route takes you through the Carnelian Coast and Abbey Rock without passing through Fallen London, you can purchase Supplies at the Carnelian Coast then zail to Abbey Rock and sell it for 2 Echoes per crate through repeated dialogue. Alternatively, if the House of Harvests is present at the Iron Republic, you can pick up the Supplies there, zail to Abbey Rock and then sell it for 5 Echoes per crate. Remember to leave some supplies for yourself! If you are heading straight to Fallen London from the Carnelian Coast, then I advise exploiting The Coffee Trade listed above instead.

The Dream-Snakes Trade

A rather unorthodox trade method requiring some zailing, having recruited the Tireless Mechanic and dined with him and the sisters at Hunter’s Keep. It is a lucrative route if you are restricted to making small hauls as it has a big profit-to-haul ratio. You first have to collect Clay Men at Polythreme and purchase 1-6 Empty Mirrorcatch Boxes at Khan’s Shadow or Khan’s Heart (requires Nephrite Ring). You then head to Hunter’s Keep, where you turn it all into Serpent-Traps; however, you will need one Tale of Terror!!, one Zee-story and one Memory of Distant Shores for each Serpent-Trap you’re making, which may limit your capability to do so as these cannot be readily purchased. After that you turn the Serpent-Traps into Mirrorcatch Boxes Full of Very Angry Dream-Snakes through dialogue with the Tireless Mechanic. You then zail to Khan’s Shadow and sell them for 230 Echoes per box (not including whatever costs incurred to acquire the necessary stories). This trade is limited, however, due to the fact you cannot collect more than 6 Clay Men at a time (hence why it’s advised to only purchase max. 6 Empty Mirrorcatch Boxes at a time).

However, once Hunter’s Keep has burned to the ground, the requirements for making Serpent-Traps there shift. It will no longer require stories, but instead require 5 Supplies and 1 Foxfire Candle per Serpent-Trap. It is advised that you purchase these at Fallen London (before heading out to collect Clay Men and buying mirrorcatch boxes), unless you have a Nephrite Ring, in which you should purchase the Foxfire Candles at Khan's Heart while buying mirrorcatch boxes. This shift reduces the profit to 100-110 Echoes per box, although it does remove the stories-cost.

Advanced Trading

Trade methods plagued by very long zailing distances and/or high capital requirements. But if exploited correctly, they can bring a tidy sum of Echoes.

The Sapphire Trade

This trade method requires a lot of capital and a lot of zailing, but can be very lucrative at big hauls. You head to the Carnelian Coast where you purchase Caskets of Sapphires. You then head to either Polythreme to earn a profit of 9 Echoes per casket or the Chelonate for a profit of 13 Echoes per casket. If you’re heading straight to Fallen London from the Carnelian Coast, I suggest exploiting The Coffee Trade listed above instead (or in conjunction with this one) as it brings a 2 Echoes higher profit than if you were to sell sapphires at Fallen London.

The Monkey-Wine Trade

An unconventional method that requires a lot of zailing, access to the Wildweald Court in the Empire of Hands as well as a Wildweald Status of at least 15. It is only advisable if you can make big hauls to alleviate the zailing costs or if you're headed to the Empire of Hands anyway. You stock up on Casks of Mushroom Wine at Fallen London and then zail to the Empire of Hands and enter the Wildweald Court. You then exchange the wine for Sacks of Darkdrop Coffee in a 1:1 exchange by giving it as gift through a dialogue option. You then zail back to Fallen London where you sell the coffee for 23 Echoes per sack. Another option than selling it at Fallen London is explained in The Far-East Trade-route under Trade-routes.

The Monkey-Honey Trade

Another unconventional method involving a lot of zailing, access to the Wildweald Court in the Empire of Hands and a Wildweald Status of at least 15. It is only advisable if you are headed to both the Empire of Hands and the Carnelian Coast (or the Iron Republic if you have the House of Pleasures). If you're heading to Fallen London after the Empire of Hands, but before going to the Carnelian Coast, then it's advised to exploit The Monkey-Wine Trade listed above instead of this one due to higher profits. You stock up on Firkins of Prisoner's Honey at Fallen London, but you need to make sure you will have room for the double the amount of Prisoner's Honey you're bringing once you're at the Empire of Hands. You then zail to the Empire of Hands and enter the Wildweald Court from which you exchange the honey for Romantic Literature in a 1:2 exchange by giving it as gift through a dialogue option. You then zail to the Carnelian Coast or the Iron Republic (with House of Pleasures) and sell it for a 19 Echoes profit per honey (9.5 Echoes profit per literature).

The Parabola Trade

Another unorthodox trade method which is mostly preferable if you are headed to Irem anyway, but can still be lucrative if you have the space and capital. You want to stock up on Sacks of Darkdrop Coffee Beans. Following are the possible suppliers:

• Fallen London - 50 Echoes per sack
  
• Khan's Heart - 40 Echoes per sack (requires Nephrite Ring)
  
• Carnelian Coast - 38 Echoes per sack
  
• Adam's Way - 38 Echoes per sack
  
• Iron Republic - 38 Echoes per sack (requires House of Milks)

When you arrive at Irem you can trade the coffee to Bales of Parabola-Linen in a 1:1 exchange. Then you sell the linen either at Fallen London for a profit of 10-22 Echoes per linen or at Adam’s Way for a profit of 13-25 Echoes per linen. Note that this is contested by The Coffee Trade if you’re buying the coffee somewhere other than Fallen London. It depends on what is most convenient for you at the time; either traveling to Fallen London to sell off the coffee or traveling to Irem for the linen. NB: If you wish to do more than just trade at Adam’s Way, remember to bring either news from London, a port report from Mount Palmerston or an Unfinished Log.

The Varchaasi Trade

Another bartering trade method that also includes quite a lot of zailing, although this one has zero capital requirement. With the "Something Awaits You" condition, you zail to the Principles of Coral. There you look for Scintillack which requires Mirrors, which will yield 1-3 Scintillack (you will still get 1 Scintillack even if you fail). However, if you've won the final game in the Principality storylet, failing the Mirrors challenge will yield no Scintillack, and succeeding the challenge will always only yield 1 Scintillack. This greatly dimishes the opportunity for profit yet is still exploitable for a small profit if you're headed to the Principles of Coral and Varchas anyway.
The next step is to zail all the way to Varchas, again you will need to have Something Awaits You condition with you. At Varchas, you enter the city and head to the Temple of Mihir at its center. There you trade the Scintillack for 2 Outlandish Artifacts per piece. This can be done 4 times (given you do nothing else at Varchas but trade Scintillack) before having to leave the city. Instead of leaving the port, you can stick around until SAY refreshes and then re-enter the city, if you have more Scintillack to trade. The artifacts can be sold either at Khan's Heart or at the University in Fallen London for 100 Echoes per piece. Important note: If you have started the Pilgrimage in Varchas, you are effectively unable to exploit this trading method for the remainder of your current captain's life.
This method is contested by the Scintillack Harvest. It depends on what is more conventient and also whether your additional zailing costs (including going to Khan's Heart or Fallen London) are covered by the 130 Echoes higher profit per Scintillack you get from the Varchassi Trade.

Surface Trading

Trading methods that include visiting the Surface. These methods differ from all the rest in that they all have a fixed cost per run that stay the same no matter what. The fixed cost is the cost of fuel and supplies it takes to get to the Surface (and to Naples). Following trade methods have had the fixed costs incorporated in calculating profits.
You will always need at least 22 Fuel and 2 Supplies to go to the Surface (though having a bit more is preferable, since you want to be able to get back to Fallen London once you return to the Neath). It is advised to purchase the Fuel at Fallen London or the Iron Republic than at the Cumaean Canal. The Iron Republic is an excellent choice for purchasing the necessary Fuel, as it only costs 8 echoes per unit there as well as being in close proximity to the Canal. It is also advised to cover your Supplies expenses by re-stocking the spent 2 Supplies at Naples for a cost of 5 Echoes (though you will still need to have 2 Supplies in your stock to get to the Surface first). All Surface trading methods assume that you re-supply the 2 Supplies at Naples.

The Vienna Trade

The most straightforward and lucrative of the Surface trading methods. Firstly, you purchase Sacks of Darkdrop Coffee Beans at Fallen London, Khan’s Heart (requires Nephrite Ring), the Carnelian Coast, Adam’s Way or the Iron Republic (requires House of Milks). You then go to the Cumaean Canal and from there you then head to the Surface and to Naples. From Naples you take the train to Vienna. The train ride costs 10 Echoes, which covers the return-trip as well. At Vienna you establish a business relationship with a coffee house that buys the coffee from you. Following are two tables displaying profit per piece using different coffee-suppliers. The first is if you bought the 22 Fuel from Fallen London, and the last is if you bought the 22 Fuel from the Iron Republic:

Fallen London Fuel:

Profit per Piece	6	7	8	9	10	15	20	25	30	35	40	45	50
Fallen London	-10	-4.29	0.	3.33*	6	14	18	20.4	22	23.14	24	24.67	25.2
Khan's Heart	0.	5.71*	10**	13.33	16	24	28	30.4	32	33.14	34	34.67	35.2
Carnelian Coast Adam's Way Iron Republic	2*	7.71**	12	15.33	18	26	30	32.4	34	35.14	36	36.67	37.2

Iron Republic Fuel:

Profit per Piece	5	6	7	10	15	20	25	30	35	40	45	50
Fallen London	-9.2	-2.67	2*	10.4	16.93	20.2	22.16	23.47	24.4	25.1	25.64	26.08
Khan's Heart	0.8*	7.33**	12	20.4	26.93	30.2	32.16	33.47	34.4	35.1	35.64	36.08
Carnelian Coast Adam's Way Iron Republic	2.8*	9.33**	14	22.4	28.93	32.3	34.16	35.47	36.4	37.1	37.64	38.08

* Are the profit per piece corresponding to what minimum quantity of coffee yields profit.
** Are the profit per piece corresponding to what minimum quantity of coffee that yields higher profit than The Coffee Trade.

Note, that this trading method is contested by The Coffee Trade if you're getting the coffee from somewhere other than Fallen London. It depends on which is more convenient for you to do and whether you have a quantity that at least corresponds to the ** of the above tables.
NB: If you wish to do more than just trade at Adam’s Way, remember to bring either news from London, a port report from Mount Palmerston or an Unfinished Log.

An important note: This trade method is limited, as the business relation with the café will end at some point. What exactly causes it to end is unclear (time that has passed? The amount of coffee you have sold?), but definitely inevitable.

The Mediterranean Trade

While in Naples you can carry cargo across the Mediterranean at the cost of 10 Fuel, 2 Supplies and 1-3 Zailors. Because you can buy cheap Supplies and relivately cheap Fuel in Naples, the Mediterranean Trade will always be profitable, even if you fail the challenge (though it is much more profitable if you succeed it), as you can re-stock in Naples (lowest profit is 40 Echoes per run and highest profit is 390 Echoes per run; not counting the 22 Fuel and 2 Supplies you spent getting to Naples). The only limitation is Zailors as you cannot recruit more on the Surface, so the most critical resource you must watch if you decide to do a lot of Mediterranean trading is Zailors (yet remember to re-stock on the Supplies you consumed in Naples once you head back to the Neath, as it is cheapest in Naples). If you are only doing the Mediterranean Trade and none of the other Surface Trading methods, you will need at least 1 succeeded challenge or 6 failed challenges (though you will probably get 1 success before reaching 6 failures) for the trip to the surface to be profitable.

The Trans-Unterzee Trade-route

The Wine Trade + The Literature Trade + The Sapphire Trade + The Ivory Trade + The Clay Man Haul
An extensive trade-route that requires high amounts of zailing and capital and (optional) a Nephrite Ring. Unless you skip some steps to make for a shorter trade-route, it is advised to either make big hauls or have other objectives at the ports.

1. Purchase Casks of Mushroom Wine at Fallen London.
   
2. Zail to Khan’s Heart and sell the wine for a profit of 3 Echoes per cask.
   Or zail straight to the Carnelian Coast to sell the wine for a profit of 2 Echoes per cask and skip steps 3-4. This is advised if you do not have access to the Nephrite Quarters.
   
3. Purchase Romantic Literature at Khan’s Heart.
   
4. Zail to the Carnelian Coast and sell the literature for a profit of 3 Echoes per piece.
   
5. Purchase Caskets of Sapphires at the Carnelian Coast
   
6. Zail to the Chelonate and sell the sapphires for a profit of 13 Echoes per casket.
   Or zail straight to Polythreme to sell the sapphires for a profit of 9 Echoes per casket and skip steps 7-8.

8. Zail to Polythreme and sell the ivory for 4 Echoes per piece.

Very thorough. You didn't mention one I've not figured out: when in Gaider's Mourn there is an option to collect echoes for the delivery of stolen ships. The pirate trade, or somesuch. Any ideas/clues?
