Facet Coat of Crafting ★★

Taken all the way down to base materials, one Facet Coat of Crafting is 2 crafting steps deep and needs 3 intermediates — Pliable Glass Fiber ×4, Ethereal Silk ×3 and Sea Swallow Leather ×1 — which resolve to 8 distinct raw materials totalling 46 units, plus 39 crystals.

That bill outweighs 12,540 of the 13,602 recipes tracked here and 1,838 of the 1,968 Weaver ones, and 4,464 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 35 are burned by the intermediates, so the real crystal cost is 16 Lightning Cluster, 8 Water Cluster, 8 Wind Cluster and 1 other kind.

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

3 of the 8 raw materials come out of the ground, and 2 of them are time-gated: Ethereal Cocoon (8:00, 20:00) and Sandalwood Sap (2:00, 14:00). The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, Sea Swallow Leather has the widest use: 124 recipes call for it, spanning six of the eight crafting classes.
