Lab/Railway[edit]

Lab/Railway Grinds

Action	Prerequisite	Input	Requirement to 100%	Output	Note
Dredge the river	N/A	2 x Survey of the Neath's Bones	467 Watchful	1
Disambiguate the Eolith 2	Experimental Object exactly 810 (Disambiguate an Eolith)	10 x Laboratory Research	N/A	1	Only feasible with low Kataleptic Toxicology level, even at 0 you only have 40% to get an artefact. The bright side is the rare failure also might give you a fate-locked item otherwise.
Leave the barge (The Persephone)	Involved in a Railway Venture 60	3/5 x Esteem of the Guild	N/A	1-10	Probably the better way to get the item in bulk. Best to get A Member of the Gondoliers 6 (Doctore of the Guild) for the non-randomize route and the discount price.
Reach towards the shore 2	Route: The Waswood	N/A	N/A	1	Very unpredictable and inefficient. Best to look elsewhere.
Sell your skeleton to an Enthusiast of the Ancient World	Route: The Bone Market	A finished skelly	225 Shadowy at 3 Skeleton: Self-Evident Implausibility	Your Skeleton: Antiquity	Also is a great way to get those artefacts. Might eat into your Exhaustion reserve, though.
