Facet Boots of Crafting ★★

Taken all the way down to base materials, one Facet Boots of Crafting is 3 crafting steps deep and needs 4 intermediates — Pliable Glass Fiber ×3, Chalicotherium Leather ×2, Dwarven Cotton ×1 and 1 other — which resolve to 7 distinct raw materials totalling 33 units, plus 31 crystals.

That bill outweighs 10,907 of the 13,602 recipes tracked here and 1,636 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 27 are burned by the intermediates, so the real crystal cost is 7 Lightning Crystal, 6 Earth Cluster, 6 Lightning Cluster and 2 other kinds.

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

2 of the 7 raw materials come out of the ground, and one of them is time-gated: Sandalwood Sap (2:00, 14:00). 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.
