Alright, so I did some math regarding the usefulness of skeleton-building for HS grinding (or money grinding, actually) and I’ve come to the conclusion that this is in fact among the best grinds available at the moment, if you can access Parabola, Ealing Gardens (and obviously the Bone Market) and have the Iron-Toothed Terror Bird from Whitsun.
I’d appreciate this if someone looked over it to see if I haven’t forgotten anything crucial:
Let’s say that we want to grind Hinterland Scrips in a mostly self-contained fashion. What follows is an estimation of actions you need for the individual parts:
Torso - Thorned Ribcage: from hunting the Terror-Bird; this is now trickier due to the outfit lockdown; at a minimum, it needs 6 actions; failing a few leads to a quite reasonable expectation of ~9 actions. Let’s be conservative and go with a Glasswork use attempt and overall 4 failures, or 10 actions.
Skull - Sabertoothed Skull: takes 1 action to make in Ealing Station and costs 4900 Bone Fragments and 125 Nodules of Warm Amber
Limbs - Ivory Humeruses: take 8 actions and 4400 Bone Fragments to make Orange-Apples in Parabola + another ~5 actions to convert into the Humeruses, if the Persuasive challenge is at 80%
Tail - Tomb-Lion’s Tail: takes 1 action, 200 Bone Fragments and 2 Nodules of Warm Amber to make in Ealing Station.
To this, you need to account for travel to Parabola and back and to Ealing and back, which would cost a total of 4 actions and 50-100 Drops of Honey. As a side benefit, going to Ealing should provide 1 Rumour of Upper River, unless your banditry is overly rampant.
Now, for the Bone Market part: you need 1 action at the beginning, 1 for each of skull, limbs and tails, 1 for declaring as a monkey and hopefully 1 for sale. The total action cost is then 9.
If you add the actions up, you get 10+1+8+5+1+4+9 = 38 actions to make a skeleton with value 19750 p., 1 amalgamy, 2 menace and 2 antiquity.
What you get depends on who you sell to; with the Gothic Writer, you obtain 400 Hinterland Scrips + 4 Carved Balls of Stygian Ivory (or 10E value). You can go for 400 Nightsoil + 2 Rubbery Pies (sell to the Rubbery Collector) or 395 Memories of Light + 4 Tailfeathers (totalĺing 207.5 E)
Importantly, you can also sell the skeleton for Bone Fragments (and, very occasionally, for Warm Amber) - which you need to obtain the bones.
For the same skeleton composition, you get 19755 Bone Fragments + 2 Unearthly Fossils. The kicker here is that if you do the resource grinding at the same time, you obviate a need to use another 4 actions for entering Ealing and Parabola in this cycle - the second skeleton will thus only cost 34 actions to make. Now, the need of Bone Fragments for each cycle is 4400+4900+200 = 9500, slightly less than a half of this skeleton value. I.e., you need to add ~17 actions, getting to 55 actions per 400 HS/207.5E
To be completely fair, you also need 127 Nodules of Warm Amber per cycle; you can sell the same skeleton for 2000 Warm Amber + 2 Knobs of Scintillack. You will need to do this quite rarely, in any given cycle, this translates into slightly over 2 actions. So again, conservative total estimate of actions will be 58 (55+3).
For these 58 actions, you will get 400 HS (~6.89 HS per action, much more than the 4 HSpA assumption which started this thread in the first place) + 10E worth of Stygian Ivory, or whatever payout you choose. In terms of selling for sheer echoes, you can get 207.5 E/ 58 actions or 3.58 EPA)
This is already quite solid, plus you also get 1 Unearthly Fossil per cycle. You pay 100 Honey to enter Parabola once every cycle (number of cycles), but you get 1 Rumour of Upper River from entering Ealing. Let’s say these effectively cancel each other out.
If you don’t fail quite so often and/or are more liberal with the rounding down, you might be looking at perhaps 55-56 actions in total. That would lead to 7.27 HSPA or 3.83 EPA - whopping numbers. This is even better than grinding Infernal Sharpshooter Rifles in your lab and selling them at Jericho, which according to the wiki takes 64 actions (63 for research, 1 for sale) and thus results in ~7.03 HSPA with maximum Train Luxury (450 HS per rifle).
The Parabola-Ealing-Bone Market grind is finnicky and requires a lot of setup, that is true. But for the endgame players going for Jericho and any future stations (even for Ealing Development after the Butcher’s shop), this represents a very good source of Hinterland Scrips or Echoes. (And Memories of Distant Shores for Jericho Canal grinding as well).
All in all, this seems very good, much better than not using the Bone Market. I’m curious to see if the rest of you guys can find any crucial mistake in my calculations and schemes, or if it really is this lucrative.
UPDATE:
Now that the Outfit lock has been lifted, we can probably shave about two actions from the total costs. That would get the whole carousel at ~53 actions, or 3.91 EPA / 7.54 HS (or other rewards including Bessemer Steel and Memories of Distant Shores) per action / 559 Bone Fragments per action.
Basically, this is the first rate option to get pretty much anything the Bone Market can sell you.
