Thalassic Favour from Skulls in Coral obtained from the Persephone
Worth noting that should you end up being short on items to exchange for <a href="/wiki/Thalassic_Favour" title="Thalassic Favour">Thalassic Favour</a> at the end of the week, it seems like it should be possible to obtain quite a lot of <a href="/wiki/Skull_in_Coral" title="Skull in Coral">Skull in Corals</a> from <a href="/wiki/Charter_a_barge_to_the_Persephone" title="Charter a barge to the Persephone">Charter a barge to the Persephone</a> (assuming you've developed the railroad to Jericho Locks and have high enough <a href="/wiki/A_Member_of_the_Gondoliers" title="A Member of the Gondoliers">A Member of the Gondoliers</a>). To fund this, use <a href="/wiki/Provide_news_from_London" title="Provide news from London">Provide news from London</a>, which requires 2x <a href="/wiki/Sworn_Statement" title="Sworn Statement">Sworn Statement</a> and 40x <a href="/wiki/Memory_of_Distant_Shores" title="Memory of Distant Shores">Memory of Distant Shores</a> (the latter of which can be stocked up on with <a href="/wiki/Gather_flotsam_for_the_King-in-Coral" title="Gather flotsam for the King-in-Coral">Gather flotsam for the King-in-Coral</a> this week). A quick calculation indicates that you might be able to gain ~5000 <a href="/wiki/Memory_of_Distant_Shores" title="Memory of Distant Shores">Memory of Distant Shores</a> this week, so pairing that with 250 <a href="/wiki/Sworn_Statement" title="Sworn Statement">Sworn Statements</a> would yield 250 <a href="/wiki/Esteem_of_the_Guild" title="Esteem of the Guild">Esteem of the Guild</a>, or ~80ish trips to the Persephone, which will yield at least 80 <a href="/wiki/Skull_in_Coral" title="Skull in Coral">Skull in Corals</a>, or 10000 <a href="/wiki/Thalassic_Favour" title="Thalassic Favour">Thalassic Favour</a> minimum. This is unlikely to be EPA-favorable, but it seems like a useful way to make up any deficits next week.
