Expeditioner's Kecks ★★★

Taken all the way down to base materials, one Expeditioner's Kecks is 2 crafting steps deep and needs 1 intermediate — Ramie Thread ×1 — which resolves to 5 distinct raw materials totalling 11 units, plus 7 crystals.

That bill outweighs 5,999 of the 13,602 recipes tracked here and 737 of the 1,968 Weaver ones, and 4,464 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 2 are burned by the intermediates, so the real crystal cost is 3 Lightning Cluster, 2 Lightning Crystal and 2 Wind Cluster.

Every step is Weaver work, from a Lv 54 intermediate up to the Lv 60 finish, so one class covers the whole chain.

2 of the 5 raw materials match a gathering node, none of them timed; the other 3 come from vendors, drops or content this site does not track.

Of the intermediates, Ramie Thread has the widest use: 85 recipes call for it, spanning three of the eight crafting classes.
