Carpenter's Workboots ★

Taken all the way down to base materials, one Carpenter's Workboots is 2 crafting steps deep and needs 3 intermediates — Hippogryph Leather ×1, Rubber ×1 and Silk Thread ×1 — which resolve to 5 distinct raw materials totalling 6 units, plus 12 crystals.

That bill outweighs 4,542 of the 13,602 recipes tracked here and 537 of the 1,844 Leatherworker ones, and 4,464 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 7 are burned by the intermediates, so the real crystal cost is 6 Earth Crystal, 3 Lightning Crystal, 2 Wind Crystal and 1 other kind.

The chain crosses three disciplines — Leatherworker to Lv 50, Weaver to Lv 50 and Alchemist to Lv 7 — so no single class can finish it unaided.

4 of the 5 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, Rubber has the widest use: 191 recipes call for it, spanning four of the eight crafting classes.
