Dredge the river	N/A	2 x	467 Watchful	1
Disambiguate the Eolith 2	exactly 810 (Disambiguate an Eolith)	10 x	N/A	1	Only feasible with low 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)	60	3/5 x	N/A	1-10	Probably the better way to get the item in bulk. Best to get 6 (Doctore of the Guild) for the non-randomize route and the discount price.

Sell your skeleton to an Enthusiast of the Ancient World	Route: The Bone Market	A finished skelly	225 Shadowy at 3	Your	Also is a great way to get those artefacts. Might eat into your Exhaustion reserve, though.
