Build on the Skeleton with Seven Necks,

That is the first action

Unprovenanced Artefact sourcing from Dig a little distance from the river

That would be 15.2 Actions (sourcing <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> from <a href="/wiki/Assemble_your_conclusions" title="Assemble your conclusions">Uni-Lab</a>)

sourcing from Moonlit Woods (Guide)

That would be 16 (3 to enter, 8 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> from <a href="/wiki/Decipher_the_signage" title="Decipher the signage">Spiralhügel</a>, random I know, but that seemed most optimal, we do not count the artefacts here, but 3 actions to gain 12 <a href="/wiki/On_the_Scent" title="On the Scent"><img alt="" src="/w/images/thumb/5/56/Fox2.png/20px-Fox2.png" decoding="async" loading="lazy" width="20" height="26" srcset="/w/images/thumb/5/56/Fox2.png/30px-Fox2.png 1.5x, /w/images/thumb/5/56/Fox2.png/40px-Fox2.png 2x" /></a>, and 2 to get payed)

Affix a Bright Brass Skull to your (Skeleton Type)*7,

That is 10.68 (7 actions to affix, and 3.68 since the Brass does need to come from somewhere)

sourcing from Duplicate the wings of a Focused Albatross

That is 7.75 actions (sourcing from <a href="/wiki/L._B._Industries_(Guide)" title="L. B. Industries (Guide)">L. B. Ind.</a> and <a href="/wiki/Accept_a_commission" title="Accept a commission">Helicon House</a> with <a href="/wiki/Read_a_poetic_missive" title="Read a poetic missive">alt Inspired... letters</a>, but you would be better off grinding them in the <a href="/wiki/Keep_it_in_total_darkness" title="Keep it in total darkness">Uni-Lab</a> (at a respectable rate of 28.5 RPA) you would get 5.51 out of it

Put an Albatross Wing on your (Skeleton Type)*2,

Is indeed 2

Declare your (Skeleton Type) a completed Bird

That is 1

sell on a bird and Amalgamy week and use 1 Hastily Scrawled Warning Note each time

And 1 last action

While sold on Bird Week, that is 21.93 MoDS per Action!... And 394.44 Echoes in debt, <a href="/wiki/Final_Breath" title="Final Breath"><img alt="" src="/w/images/thumb/1/19/Oxygen.png/20px-Oxygen.png" decoding="async" loading="lazy" width="20" height="26" srcset="/w/images/thumb/1/19/Oxygen.png/30px-Oxygen.png 1.5x, /w/images/thumb/1/19/Oxygen.png/40px-Oxygen.png 2x" /></a> Amalgami gain does not break even. But I will factor that in as an average loss of 7.22 Echoes every time we use MoDS.

Now, (60 + 2.5 × 5.5 + 22.5 × 2.5 - 3 * (40/21.93) * 7.22 ) / ( 3 * ( 2/(7/3) + 40/21.93) + 3 + 2 + 2.5 (selling VoCC to the Church in the Wild))A = 5.82 EpA
