Tough analyse indeed. We're near， though something differs.

• That would be 15.2 Actions

To build 1 skeleton, <a href="/wiki/Skeleton_with_Seven_Necks" title="Skeleton with Seven Necks"><img alt="" src="/w/images/thumb/1/16/Bone18.png/20px-Bone18.png" decoding="async" loading="lazy" width="20" height="26" srcset="/w/images/thumb/1/16/Bone18.png/30px-Bone18.png 1.5x, /w/images/thumb/1/16/Bone18.png/40px-Bone18.png 2x" /></a> is needed, which means <a href="/wiki/Unprovenanced_Artefact" title="Unprovenanced Artefact"><img alt="" src="/w/images/thumb/2/2a/Guisemale.png/20px-Guisemale.png" decoding="async" loading="lazy" width="20" height="26" srcset="/w/images/thumb/2/2a/Guisemale.png/30px-Guisemale.png 1.5x, /w/images/thumb/2/2a/Guisemale.png/40px-Guisemale.png 2x" /></a> are enough. Play <a href="/wiki/Dig_a_little_distance_from_the_river_2" title="Dig a little distance from the river 2">Dig a little distance from the river 2</a> twice, costing <a href="/wiki/Survey_of_the_Neath%27s_Bones" title="Survey of the Neath's Bones"><img alt="" src="/w/images/thumb/4/43/Map.png/20px-Map.png" decoding="async" loading="lazy" width="20" height="26" srcset="/w/images/thumb/4/43/Map.png/30px-Map.png 1.5x, /w/images/thumb/4/43/Map.png/40px-Map.png 2x" /></a>. That would be less than 3 actions. How could you get 15.2?

• 8 to source Volume of Collated Research from Spiralhügel

Just use MoDS from previous skeletons by <a href="/wiki/Dealing_with_the_deviless" title="Dealing with the deviless">Dealing with the deviless</a> to source <a href="/wiki/Volume_of_Collated_Research" title="Volume of Collated Research"><img alt="" src="/w/images/thumb/9/9b/Library.png/20px-Library.png" decoding="async" loading="lazy" width="20" height="26" srcset="/w/images/thumb/9/9b/Library.png/30px-Library.png 1.5x, /w/images/thumb/9/9b/Library.png/40px-Library.png 2x" /></a>.

• sourcing from L. B. Ind. and Helicon House

It's far better to source <a href="/wiki/Bone_Fragments" title="Bone Fragments"><img alt="" src="/w/images/thumb/1/1b/Boneshard.png/20px-Boneshard.png" decoding="async" loading="lazy" width="20" height="26" srcset="/w/images/thumb/1/1b/Boneshard.png/30px-Boneshard.png 1.5x, /w/images/thumb/1/1b/Boneshard.png/40px-Boneshard.png 2x" /></a> and <a href="/wiki/Nodule_of_Warm_Amber" title="Nodule of Warm Amber"><img alt="" src="/w/images/thumb/0/06/Amber_red.png/20px-Amber_red.png" decoding="async" loading="lazy" width="20" height="26" srcset="/w/images/thumb/0/06/Amber_red.png/30px-Amber_red.png 1.5x, /w/images/thumb/0/06/Amber_red.png/40px-Amber_red.png 2x" /></a> from bone market. See <a href="/wiki/Sell_a_complete_skeleton_to_the_Bone_Hoarder" title="Sell a complete skeleton to the Bone Hoarder">Sell a complete skeleton to the Bone Hoarder</a> and <a href="/wiki/Sell_your_skeleton_to_a_Zailor" title="Sell your skeleton to a Zailor">Sell your skeleton to a Zailor</a>.

• And 1 last action

The challenge is <a href="/wiki/Shadowy" title="Shadowy"><img alt="" src="/w/images/thumb/8/85/Sidebarshadowy.png/20px-Sidebarshadowy.png" decoding="async" loading="lazy" width="20" height="26" srcset="/w/images/thumb/8/85/Sidebarshadowy.png/30px-Sidebarshadowy.png 1.5x, /w/images/thumb/8/85/Sidebarshadowy.png/40px-Sidebarshadowy.png 2x" /></a> 1050. You can't succeed in once, and there's <a href="/wiki/Suspicion" title="Suspicion"><img alt="" src="/w/images/thumb/b/ba/Sidebarsuspicion.png/20px-Sidebarsuspicion.png" decoding="async" loading="lazy" width="20" height="26" srcset="/w/images/thumb/b/ba/Sidebarsuspicion.png/30px-Sidebarsuspicion.png 1.5x, /w/images/thumb/b/ba/Sidebarsuspicion.png/40px-Sidebarsuspicion.png 2x" /></a>.

• And 394.44 Echoes in debt

I don't know your math, but <a href="/wiki/Bright_Brass_Skull" title="Bright Brass Skull"><img alt="" src="/w/images/thumb/a/a5/Skullbrass.png/20px-Skullbrass.png" decoding="async" loading="lazy" width="20" height="26" srcset="/w/images/thumb/a/a5/Skullbrass.png/30px-Skullbrass.png 1.5x, /w/images/thumb/a/a5/Skullbrass.png/40px-Skullbrass.png 2x" /></a> is self-sufficient. No need to buy it from the Bazzar.

It's too hard to calculate using only one equation, and I'm using excel to balance various sources. See my calculation in <a rel="nofollow" class="external free" href="https://z1.wzznft.com/i/2024/04/27/ieprf1.png">https://z1.wzznft.com/i/2024/04/27/ieprf1.png</a>.

By the way, can I write the above into <a href="/wiki/Money-Making/Lategame" title="Money-Making/Lategame">Money-Making/Lategame</a>?
