Carbonweave Boots of Gathering ★★

Taken all the way down to base materials, one Carbonweave Boots of Gathering is 3 crafting steps deep and needs 5 intermediates — Rubber ×2, Sewing Thread ×2, Pterodactyl Leather ×1 and 2 others — which resolve to 9 distinct raw materials totalling 20 units, plus 44 crystals.

That bill outweighs 7,876 of the 13,602 recipes tracked here and 1,025 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 40 are burned by the intermediates, so the real crystal cost is 14 Lightning Crystal, 14 Wind Crystal, 5 Earth Cluster and 4 other kinds.

The chain crosses four disciplines — Leatherworker to Lv 60, Blacksmith to Lv 60, Weaver to Lv 60 and Alchemist to Lv 7 — so no single class can finish it unaided.

7 of the 9 raw materials come out of the ground, and one of them is time-gated: Sphalerite (2:00, 6:00, 10:00, 14:00, 18:00, 22:00). The widest gap between consecutive opening times is 4 Eorzean hours, about 12 real-world minutes.

Of the intermediates, Rubber has the widest use: 191 recipes call for it, spanning four of the eight crafting classes.
