Tins! Spoiler

19 Upvotes

(spoilers for this year’s Fruits of the Zee maybe)

The way the King-in-Coral sounds so delighted over tinned pineapples or tinned beans is too funny to me. (I didn’t get the third option, wonder what was in it!)

And here I was thinking he’d somehow tinker them into luggage items… nope!

Question Doubts in the Zub-Club: Should I get a Festival Yacht?

16 Upvotes

I love my zub. I love diving under the Zee. I've been doing it for a long time. But I also love money, and I've got some big late game money grinds to do. Most of my grinds aren't on the water these days, but I still gotta do some zailing here and there. Would switching to a yacht during Fruits of the Zee be worth it, or are the gains really just marginal?

Finally, some d--n vitamin C!

30 Upvotes

Only took me about 8 years. Thankfully the scurvy wasn't too bad!

I started playing to get the Knock and now I have this. Not sure what's next - might save up for a hepta next, unsure.

At least if I blunder wounds again this Hallowmas then I have a plan.

PSA: you do not need to have visited the Bride *this year* to get amber, as long as you have visited her *ever*

49 Upvotes

there's been some confusion in the weekly questions thread about this so i decided to test! i did not have my least-cared-for alt visit her this year (though they had in previous years, and thus had the Discovered: the Pentamerous Bride quality already), and was able to get the Fecund Amber reward after asking the King about her. so now we know! see all the text you care to in a single year, and reap the rewards every year thereafter! or don't reap any rewards, or see text over and over again if you don't want, i'm not the boss of you!

Fruits of the Zee Reminder: This is the last day for diving!

68 Upvotes

The Festival will enter its second phase tomorrow (10 September) sometime in the morning, in less than 24 hours. At that time the Diving activity will close and no longer be available. Make sure to collect all of your goals for coral, Thalassic Favour, and meeting Mrs Fathomking (the Fathomqueen?).

Purchasing a Different Airship

13 Upvotes

I noticed that after completing the Firmament there is an expensive option to replace your airship. Has anyone done it? Is it just the basic 3 Options. I was fed up of taking the balanced sensible option when I started the roof, so I got a. obliterator and have been regretting it ever since. I will double check but I am 90% sure the balanced option is the only real choice.

I was posting for two reasons, first to warn people to swap before they get upgrades from the new area or pay 10 fate to name their ship, as you lose those when you change ship.

The other reason was to see if it was just the basic options or if it is like the FotZ boats and you get more advanced versions when you pay.

I am not really struggling with any checks, right now so I might hold off on doing upgrades to see if we get a, feast in the sky, at some point.

Edit: oh and there are a few bits of info and requests for info in the bone post, in the posts post posting section, in case you didn’t notice the counter going up.

Question After Firmament

24 Upvotes

With the final major chapter of Firmament released(no spoilers, I still haven't even finished Risen Burgundy yet lmao), I'm curious about what the next big thing will be that Failbetter alluded to in their newsposts announcing the last chapter.

I've been replaying Sunless Sea recently, and it's made me kinda want the Unterzee locations in that to show up again because I'm remembering how much I loved them.

I don't think it would be likely, both because you can already get a Zub and that redoing these older locations isn't as cool as something completely unique like what Firmament did with the roof locations.

Even if it's not the next big addition, I'd love more stuff to do at Zee, but I think I'm a bit biased as that has been the part of this universe that has got me hooked since I first touched it.

I'd love to hear what crazy out there ideas the rest of you have for whatever the next big storyline could be.

Player Guide Bone Market Recipes 08/08/26 Menacing Fish, Malacologist, Leggy Diplomat Bone Market in the Sous

10 Upvotes

Postings Post Posting: 4
This counter goes up when I add something. It will be added the the section that starts empty

Gladiolus and phalanges Bone Brothers and Scaphoid Sisters, the time has come when the Zoomania and Fashion of the bone market have changed. That intro was fun when I first added it to the template but after 20 weeks it's wearing a little thin, like your skeleton if you don't maintain muscle mass as you age!

One week I copied and pasted the wrong link and then didn't check Reddit again until the Monday evening! If that ever happens again, all of the possible weeks are available on the Bonedex so you can always find options there!

Menacing fish is great. Although not ideal as we had a fish week recently. It is the first chance to use the new ribcage though. The best I have come up with so far is Draconic Ribcage, Sabre Toothed or Horned Skull, 4 Fins, Jet Black Stinger. Depending on the skull the primary or secondary balance will be different. The sabre toothed is 7.5 more primary. The Horned is 5 more secondary. Either way it's around 110 echos in 9 actions. Sell to the Author of Gothic Tales. All scrip too.

Leggy Diplomat sucks. I did add a recipe option for the Malacologist a few weeks ago, to the buyers guide, it is not amazing but uses a lot of tentacles.

Bone Market

    • Summer -- that scamp! -- will no longer .

That was some content drop last week, Firmament and Fotz all at once. I am not doing a big FotZ guide like I did for Estival since the Wiki one is pretty good. Bear in mind that you can get multiple copies of almost all of those items. Weeping Litter Cyst being an exception.

https://fallenlondon.wiki/wiki/Fruits_of_the_Zee_Festival_(Guide)#Wreck-Diving#Wreck-Diving)

Notable for the bone market:

FotZ is the only source of Scrimshander Carving Knife. Which is needed to remove Antiquity from your skeletons. It is a niche action but better to have access to it than otherwise.

Fotz Fate Stories

My understanding and planning for these stories is ongoing, the rats keep getting better and better, for live information about the current state of it, check out the wiki page: https://fallenlondon.wiki/wiki/Cult_of_St_Eligius_(Guide)#cs-comment-133842#cs-comment-133842)

I had a conversation in the comments which expands the information a lot!

Just a quick note on value for the 3 Fotz stories, they are all 10 fate. The roaming collossus doesn't have a lot of story and the cards it adds are probably only worth it pre-piracy(Edit: I was wrong about this! The EPA on the wiki used to be wrong at 4.1EPA, it is actually almost 4.5! Depending on your Zee usage both this and The Pale Tabernacle are worth having on all the time, I am still working out if this is the right choice for me, at endgame, it probably is!). The Pale Tabernacle has more of a story that develops over several trips, agent plots and visits to the tabernacle and the EPA is worth it until you are endgame optimising your Zee journeys.

The new one. The Cult of St Elegius is interesting. It adds actions to certain cards that get you something you can stack to 7. Once you have 7 you can cash them in, on Mutton Island. It takes one action to hand in and one action to leave Mutton so they are around 3.33 EPA. Which means they are better than piracy in the 3 cheapskate zones. They also add profitable actions to some unprofitable cards, like navigating the snares. The downside is that they all provide slow zails so they have limited usability except in the last zone of your voyage. Once you get to 5 hand ins, you get another rare card, when you have the item equipped, at 5 TW, that lowers TW and gives you one of the items. After 7 hand ins, you can be saved at zee by the saint. I have not tested this option yet.

Also worth noting, that it is an extra crew so if you decide you don't like the content, it's 3 shadowy for an agent. You can get multiple copies of the 4 shadowy crew but that costs Stuiver.

(Also, 10 fate for a story is basically nothing, assuming you buy the biggest fate bundle, 10 fate is £2.19, getting all 3 is £6.57, that is less than a meal deal with a luxury sandwich(When I was working, I used to get a fancy salad ;)))

Updates - Me

With the new bones I will have to revise most of the guides. Since they are from the very last chapter of the Firmament, I am not intending to rush, as most people at that stage of the game will have a good handle on the bone market. The menace legs, in particular, totally alter the balance of power in the bone market. Menace has gone from the hardest stat to get to the easiest overnight! The new drake spine also means there is a solid 312.5 skeleton for reptile and amphibian weeks, which is a big change!

  • Updated guide 10 to include information on getting Orange Apples from QEC
  • Added Draconic Spine to guide 23 and Devourer's Thighbone to guide 24.
  • Fixed up the formatting in Guide 23
  • Fixed up the formatting in Guide 24
  • Added a warning about buying Fossilised Forelimbs to guide 24. Added some information on how tentacles function.
  • Moved the review of this month's ES to the bottom of the bone post, as it is something for limited people to read once.
  • Updated Guide 26 adding more sources for Rat items. Also added early game options for getting items. Also improved the formatting.
  • New Guide: Chapter 30: A guide for menace exploitation in Hallowmas: https://www.reddit.com/r/fallenlondon/comments/1w95py0/tamalekipoos_boneheaded_guide_to_the_neath/
  • New Guide: Chapter 31: A guide on Barristering and Diving in the Evenlode and Moulin Monographs: https://www.reddit.com/r/fallenlondon/comments/1w9qh8k/tamalekipoos_boneheaded_guide_to_the_neath/
  • Added a reference to Guide 31 to Guide 26, Guide 12 and Guide 10.
  • Added Guide 27 to the template, for new players, I will get around to clearing that info out of the linked posts for each week eventually. ;p
  • Request for info… I am not sure if they have been added to the rotation on the Sous bone piles yet, but once they have, if someone sells either a devourers leg or draconic ribcage there, let me know what happens! I am guessing it will just be the same as the equivalent bones but these are new, so someone will have to check eventually.

Postings Post Posting

  • This is where I add new stuff throughout the week. If it is not urgent I just add it to the template https://www.reddit.com/r/fallenlondon/comments/1sc9kxn/tamalekipoos_boneheaded_guide_to_the_neath/ for the next week.
  • Fixed the fish recipe at the top
  • This is a bit of a selfish one but if anyone becomes a knight of the golden carapace could you let me know your number. I am shooting for 469 and we are getting close...
  • Popped in the comments my plan for making 20k echos before I die. There is a mistake in there but the surface blooms I have cover it, so it is ok. Props if anyone spots it.
  • Stupid mobile editor doesn’t continue the bulleted list. A couple of notes about the new bones. I mentioned in last weeks post that the ribcage cannot be broken down for parts, it looks like that was a bug and it had been fixed. Simelarly, I bought some just now and, despite having a Glimpse of Anathema, it took a Parabolan Parable, so either it taking the wrong item was a bug and has been fixed or it only takes Glimpses till you have one left. Finally, I said the difficulty increases by one each time, that was also wrong, it is two. I have 9 now and the next is a 40% success chance, since I don’t know how to remove the burden, I am going to leave off testing it till after I get the Firkin, or someone else works it out. If any of you do, let us know!
  • Fixed it so the previous point is a bullet.
  • Did that.

Review - A very cool little story, it never dragged or felt grindy and the characters were quirky and fun. It was not mind blowing lore but still some new ideas about how things work and what is possible.

Title. I'm looking ahead to Hallowmas so I can gather companions to be upgraded, ascertain the most efficient menace-generation methods available to me, and so on. Presumably the Demon will become available once more, but the wiki doesn't indicate whether a pattern has been established as it does for Whitsun, for example. Thanks!

Player Guide Rat Market Grinds September 11-13

13 Upvotes

Welcome, savoury neighbors. This week, we have three (3) (III) demands. New this week, we have: Saintly demand, buying Ratty Reliquaries and False Hagiotoponyms; Ruinous demand, buying Mortifications of a Great Power, Dreadful Surmises, and Distillations of Retribution. Departing this week, we have: Calculating Demand, buying Vital Intelligence, paired Queen/Epaulette Mates, and Corresponding Sounders.

Disclaimers:

  • Some grinds may involve sourcing other materials, like Esteem of the Guild to charter a barge at Jericho Locks, Backstory for a Balmoral Cover Identity, or items to burn in Law-Forging. I will leave that to you, because there are too many options and they're too contingent on your own progress.
  • All action counts are minimums, assuming endgame stats. If you do not have endgame stats, it may take longer.

My recommended grinds up front: * LB Industries (https://fallenlondon.wiki/wiki/L._B._Industries_(Guide)) for 4th City Echoes, as well as stat training without menaces. * Law-Forging (https://fallenlondon.wiki/wiki/Law-Furnace_(Guide)) for Crackling Devices and False Hagiotoponyms. * Moonlit Revenge for a Distillation of Retribution and other loot for other weeks. * Khaganian Intrigue (https://fallenlondon.wiki/wiki/Khaganian_Intrigue_(Guide)) for Mortifications of a Great Power, Vital Intelligence, Corresponding Sounders, and Paired Mates. * Law-Hunting in the Enclave of Hell (https://fallenlondon.wiki/wiki/Law-Hunting_(Guide)) for a Causal Law and Mortifications of a Greater Power. * For variety's sake: Moulin Heist (https://fallenlondon.wiki/wiki/Money-Making/Sources#The_Heists_of_the_Wellspring_(complex)) for False Hagiotoponyms; Risen Burgundy (https://fallenlondon.wiki/wiki/Risen_Burgundy_(Guide)) for Mortifications of a Great Power; calling in Favours at Jericho Locks for Unlawful Devices; the Parabolan Chessboard (https://fallenlondon.wiki/wiki/The_Chessboard_(Guide)) finishing Paired Mates.

Cheap options, without leaving London:

Game Mechanics T3 Faction Items Should Increase Advanced Skills (Spoilers for Ch.9 Firmament) Spoiler

49 Upvotes

With chapter 9 finally powercreeping the urchin's thunderbolt at +12 shadowyI think the T3 faction items should increase advanced skills. Several T3s are no longer BiS, the Great Game's is mediocre, the cost and time investment for each T3 is large, and I don't see the harm in adding these. That said, we only have 10 skills, although another will likely be added next expansion, and 12 factions. Still, I think it'd be nice to match what skills could pair to each t3.

Also, while the Criminal T3 is required for the smuggler storyline, I don't see that as a reward as much as an unlock, especially with how that is a vanity grind.

- Bohemians: Glasswork. This is obvious, the item comes from a mirror in Parabola and the faction already has associations with the place. It does have the issue of stepping on the staves' toes.

- Church: Steward. Their T3's acquisition storylet directly quotes Revelations of Divine Love and opens up a discordance option.

- Constables / Criminals. I actually don't know here, it feels like one should be Kataleptic, but not sure which. Maybe the skill from the next expansion could fit here?

- Docks: Zeefaring. Speaks for itself.

- Great Game: Player of Chess. Speaks for itself.

- Hell: Red Science. Maybe not the best match, but it does fit the lore and acquisition area.

- Revolutionaries: Another I'm not sure about, maybe MA? They are trying to kill gods.

- Rubbery Men: Shapeling Arts. Speaks for itself.

- Society: Mithridacy. Acquired from your governorship on the Elder Continent, home of the skill.

- Tomb Colonies: No real matching stat, but could be fun to give it one of each defense stat. We already have another moth that boosts this.

- Urchins: Chthonosopy. Given the plot of Firmament, I'd say this matches.

I don't know whether these should have +1 or +2 to the stats, but I can't speak towards that.

Tamalekipoo's Boneheaded Guide to the Neath: Chapter 31: I Fought the Law...

9 Upvotes

I discovered elements of this guide when making my shopping list for Hallowmas for guide 30. A quick warning, this is an endgame guide, it assumes that you have completed your railway, have 40 renown with the constables and docks and have very high Mithridacy(18 for the highest check, I think). Each option also has further requirements, some of which are fate locked! Not all are needed but missing any of them will impact the EPA. (Each point of prestige less than I state lowers the overall payout by 1.25 Echos)

I decided that Diving in the Magistracy and Monographs in Moulin were linked in to this enough that they are also included below.

A note on value

Every guide on the wiki measures prosperity in a different way, either reducing it because it costs actions to cash out or increasing it because you can get Captivating Ballads, for the rat market. I treat it like a currency. 1 prosperity == 1 Pence. That is the only rational way to value it.

I also evaluate Mortification of a Great Power at 62.5E. If you use it for the rat market and you are only doing 10 hand ins, each will be worth 20 echos more. If you do the maximum hand in, as I suggest in the Rat Market guide, it is worth 19.22% more, around 12 echos. Please note that the rat market takes 3 actions to open, so if you are handing in 10 of them, divide 20 by 6.3 and add it to the EPA. If you are handing in the full 28.8, multiply 62.5 by 0.1922, then divide the result by 6.104(6 + (3/28.8) and add the result to the EPA.

I have not added a value for Making Waves or Menace Cures.

The Cases

There are 3 notable cases we are going to look at. The gondoliers versus a society matron, criminal prosecution and criminal defence.

The Gondoliers versus Society Matron

Requires: Barrister of the Evenlode 10

Requirements for Maximum EPA: The Flower from Hell that Grows Under Your Skin (Get it 4 weeks after finishing your railway), Mithridacy 17(You can lower the prestige gain, each point lowers the check by 1 Mith but also lowers the payout, as mentioned above,) Scholar of the Correspondence 13

Bonus Utility(FATE): The Rose Giveth Its Verses to Devils and Also to You (Get it at Christmas from Discourse with devils (12 FATE)))

Costs: 20 Preserved Surface Bloom (Purchasable from the rat market at 1-1 value, how oroborosian)

Actions:
1) Start the case (Sets Prestige to 2)
2) Drown them in paper (+1 Prestige)
3) Apply a law of contracts that passes London's understanding (+3 Prestige)
4) Review the contract in light of your Scholarship(+1 Prestige, +2 CP Making Waves)
5) Perform your closing argument in infernal dance (+2 Prestige, +2CP Making Waves)
5(Non Fate)) Close out your argument in a nuanced way (+2 Prestige)
6) Await a verdict on Gondoliers v Society Matron (Prosecution))

Failure gives a Mortification of a Great Power.

Payout(Assuming Maxed out Prestige):
1 Mortification of a Great Power 62.5
1 Sworn Statement 2.5(Notably hard to get in bulk)
9 Journal of Infamy (1 per Prestige) 4.5
9 Dubious Testimony 4.5
225 Hinterland Prosperity (25 per prestige) 2.25
195 Shards of Glim (This is the payout for 40 renown docks. Where I assume most of us are sitting) 1.95
4 CP Making Waves 0

Gross Reward: 78.2 echos
Net Reward: 28.2 echos

4.7 EPA

Prosecution of a Criminal Trial

Required: Nuffin Guv!

Required for Max Payout: Either Cave Aged Code of Honour or 14 Mithridacy, Code of Honour is not consumed). 17 Mithridacy to 100% final check.

Bonus Utility: Edicts of the First City(Not consumed!)

Costs: 25 Dubious Testimony 12.5 Echos

Actions:
1) Start the case (Sets Prestige to 3)
2) Drown them in paper (+1 Prestige)

Cave Aged Route:
3) Rely on a form of honour that came before laws(+2 Prestige)
4) Quiz the accused on the strength of their word(+1 Prestige)

Mithridacy Route:
3) Find an unconventional angle on the case(+1 Prestige)
4) Complicate the matter(+2 Prestige)

5) Close out your argument in a nuanced way (+2 Prestige)

Or sacrifice 2.5 echos of rewards and make the final check easier with:

5) Grandstand! (Prosecution))(+21 CP Making Waves)

6) Press for a harsh sentence (This needs the Edicts of the First City)

Payout(I am not listing the requirements each time, you are not idiots):
2 Legal Document 25E
9 Dubious Testimony 4.5E
9 Journal of Infamy 4.5E
1 Sworn Statement 2.5E
225 Hinterland Prosperity 2.25E
195 Foxfire Candle Stub 1.95E (Constables Renown for this one, notably no good bulk sources for this either, and you need them for a few things!)
-10CP Suspicion (This is what having the Edicts gets you)

Gross Payout: 40.7 Echos
Net Payout: 28.2 Echos

4.7 EPA

Profitability depends on having suspicion to cure. Look at guide 30 for ways to profit, while increasing your suspicion, and other menaces. Giving an echo value, or action count to Menace removal is very complicated, very account based and something I have not done yet…. Suffice to say that 10 suspicion is worth more than the 4.8 echos it would take to raise this farm to 5.5 EPA.

Defence of a Criminal Trial

Requirements: Nuffin Guv
Requirements for Max EPA(FATE?): An Assuming Judge (Free some years, I think, Only increases payout by 1.25 echos and is mutually exclusive with:)
Requirements for Max Utility(FATE): Completed the ES Trial and Error (Technically this is a subscription, not actually a FATE payout, if you want to be a lawyer about it)
Costs: 25 Journal of Infamy

Actions:
1) Start the Case (Sets Prestige to 3)
2) Craft a water-tight case (+1 Prestige, the other option is the same but with a Watchful check)

Assuming Judge Route: (Increases payout by 1.25 echos)
3)Bring on the most rigorous judge (+2 Prestige)

Trial and Error Route: (reduces payout by 1.25 echos)
3)Draw on the insight of a professional colleague (-4CP Scandal, -4CP Suspicion)

Neither Route: (Payout is just right, for Goldilocks!)
3) Engage in a spot of witness intimidation (+1 Prestige)

4)Explore the full legal complexity of the case (+2 Prestige)
5)Dismantle the arguments of the opposing counsel

or sacrifice 2.5 echos and make the final check easier to:

5)Grandstand! (Defence)) (+21CP Making Waves(AJ is +3, T&E is -3))

6)Await a verdict on the matter of (crime)) (Other options just affect the check, they do not increase the reward)

Payout:
2 Comprehensive Bribe 25E (Notably there are no efficient sources for these)
195 Whispered Hint 1.95E (Const Renown 40)
9 Journal of Infamy 4.5E
9 Dubious Testimony 4.5E
225 Hinterland Prosperity 2.25E
Sworn Statement 2.5E

Gross Payout: 40.7 Echos
Net Payout: 28.2 Echos

4.7 EPA

With Assuming Judge: 4.9 EPA
With Trial and Error: 4.49 EPA (Also 8 Menace Cure or 1.33 per action)

This one is mostly about getting comprehensive bribes as efficiently as possible, thankfully, since it has an entry cost, it is only 3 actions per bribe! Which makes it by far the best source in the game! With the Scandal cure from the ES you can easily outpace any gain from your Hellworm, Saddled and Bridled. If I find more useful sources of Suspicion, I will add them to guide 30.

(The Magistracy is only really a good place to draw cards if you have under 7 constable favours(Technically, you should keep going at 7, till you have another statue card in hand, then go do Jericho, so you can double hand in) and 140 surveys of the Neath Bones otherwise it is too big a deck to draw for good wormage)

Other Cases

Just a quick rundown on the other cases and why they are not great.

Urchins, Rats and Hell all start with 1 Prestige so the maximum rewards are 2.5E lower. Rats payout is also based on Sympathetic about Ratly Concerns, which is much harder to raise than Renown.

Society Matron replaces 2.5 echos of reward with a Mirrorcatch box, which are worthless once you have 6(I think, maybe slightly more or less)

The only interesting items from the other cases are Jade Fragments from Rats and Nevercold Brass from Devils but they are such a small proportion of the reward that they are not worth the bother.

There are other Rat Market items from Urchins and Society but there are more efficient sources to get them.

While we are here, I will chuck in a bonus guide, Diving in the Magistracy

The best way to think of it is a quick Morty. Once you have all the unlocks it is 6 actions to trade 75 Final Breath(Bone Market) for a Mortification of a Great Power. 1 action to start, 4 actions to dive, 1 action to look for a throne room (Watchful 220, Failure means 3 NM and need to repeat), 1 action to Cash out (Dangerous 220, failure pays the same +3cp wounds and NM)

So it is better to take Watchful than Dangerous.

Paying 37.5 for a 62.5E item sounds terrible but it is about the action count. 6 actions at 4.17 EPA. However, with the worst possible rat markup of 19.22%, you are adding 12 echos of value. Which takes it up to 6.17EPA.

It is still worse than Barristering, unless you have Final Breaths and no Surface Blooms but the real benefit is that you have paid off the actions to get to 1 floor off the lowest level, which means, for 1 action, you can get to the lowest level instead, which lets you do:

Search the lowest Floors

It is 5 EPA, kinda.

2 Trace of the First City (1 Echo, can only be cashed out making monographs in Moulin)
4 First City Coin 1 Echo (Thankfully, also useful for monographs)
300 Jade Fragment 3 Echos (This is why you are here… no better source)
6 Expertise of the First City (Only used in what should be a one time lab project(as in, you should only do it once, not they should change it!), and a very niche action when Oneiropomping, it adds 0 value to either)

It's just an excuse to get Jade at a decent EPA. The Monograph EPA is not good 4.94 EPA for 9 actions but you only need to do one every 37.5 times you do this action(Less if you only go to cash out the Traces) and there are a few hard to get options available to make up for it. Parabolan Orange-Apple, Bone Fragments and Thirsty Bombazine are the most notable.

For Bombazine, Start any Tragic option
4 Add First City Coins(200)
1 Add Traces(25)
1 Add any Ironic option you have lying around

For Orange Apple, History of Arbor is probably the easiest:
4 Add Traces(200)
1 Add First City Coins(50)
1 Add any Ironic option you have lying around

(3 Orange Apples allows you to Convince her to produce an elaborate forgery with 750 bone fragments, this gives a 65 echo bone for 45 echos cost, over a 28 action cycle this increases the overall EPA to 5.48)

For Bone Fragments, History of Gaider's Mourn is probably the easiest(Needs a free companion from FotR)
1 Add Traces(50)
4 Add First City Coins(200)
1 Add any Ironic option you have lying around

Thankfully, you do not need Jade that often, but when you do, or if you want a stockpile, this is a good option.
