Falconer's Bottoms ★

Taken all the way down to base materials, one Falconer's Bottoms is 3 crafting steps deep and needs 4 intermediates — Pterodactyl Leather ×2, Crawler Silk ×1, Titanium Ingot ×1 and 1 other — which resolve to 10 distinct raw materials totalling 22 units, plus 23 crystals.

That bill outweighs 8,402 of the 13,602 recipes tracked here and 1,157 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 20 are burned by the intermediates, so the real crystal cost is 9 Fire Crystal, 6 Earth Cluster, 5 Lightning Crystal and 1 other kind.

The chain crosses three disciplines — Leatherworker to Lv 60, Weaver to Lv 57 and Blacksmith to Lv 56 — so no single class can finish it unaided.

7 of the 10 raw materials come out of the ground, and one of them is time-gated: Silkworm Cocoon (1:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Crawler Silk has the widest use: 178 recipes call for it, spanning five of the eight crafting classes.
