Calfskin Rider's Cap ★★★★

Taken all the way down to base materials, one Calfskin Rider's Cap is 2 crafting steps deep and needs 1 intermediate — Megalania Leather ×3 — which resolves to 3 distinct raw materials totalling 19 units, plus 26 crystals.

That bill outweighs 7,589 of the 13,602 recipes tracked here and 958 of the 1,844 Leatherworker ones, and 4,464 recipes nest deeper.

Only 14 of those crystals go into the final step; the other 12 are burned by the intermediates, so the real crystal cost is 7 Earth Crystal, 7 Wind Crystal, 6 Earth Cluster and 1 other kind.

Every step is Leatherworker work, from a Lv 80 intermediate up to the Lv 80 finish, so one class covers the whole chain.

1 of the 3 raw materials come out of the ground, and one of them is time-gated: Ashen Alumen (10:00, 22:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Megalania Leather has the widest use: 50 recipes call for it, spanning six of the eight crafting classes.
