Martial Artist's Pumps ★★★★

Taken all the way down to base materials, one Martial Artist's Pumps is 2 crafting steps deep and needs 1 intermediate — Deinosuchus Leather ×2 — which resolves to 4 distinct raw materials totalling 16 units, plus 18 crystals.

That bill outweighs 6,959 of the 13,602 recipes tracked here and 847 of the 1,844 Leatherworker ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 12 are burned by the intermediates, so the real crystal cost is 9 Earth Cluster and 9 Wind Cluster.

Every step is Leatherworker work, from a Lv 90 intermediate up to the Lv 90 finish, so one class covers the whole chain.

1 of the 4 raw materials come out of the ground, and one of them is time-gated: Field Mustard (10:00, 22:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Deinosuchus Leather has the widest use: 33 recipes call for it, spanning four of the eight crafting classes.
