Calfskin Rider's Bottoms ★★★★

Taken all the way down to base materials, one Calfskin Rider's Bottoms is 3 crafting steps deep and needs 3 intermediates — Megalania Leather ×3, Dwarven Cotton ×1 and Dwarven Cotton Thread ×3 — which resolve to 4 distinct raw materials totalling 24 units, plus 33 crystals.

That bill outweighs 8,926 of the 13,602 recipes tracked here and 1,247 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 14 of those crystals go into the final step; the other 19 are burned by the intermediates, so the real crystal cost is 7 Earth Crystal, 7 Lightning Crystal, 7 Wind Crystal and 2 other kinds.

The chain crosses two disciplines — Leatherworker to Lv 80 and Weaver to Lv 78 — so no single class can finish it unaided.

2 of the 4 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, Dwarven Cotton has the widest use: 165 recipes call for it, spanning eight of the eight crafting classes.
