Facet File ★★

Taken all the way down to base materials, one Facet File is 2 crafting steps deep and needs 3 intermediates — Alumina Whetstone ×3, Tungsten Steel Ingot ×3 and Sea Swallow Leather ×1 — which resolve to 8 distinct raw materials totalling 41 units, plus 35 crystals.

That bill outweighs 11,923 of the 13,602 recipes tracked here and 1,468 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 31 are burned by the intermediates, so the real crystal cost is 14 Fire Cluster, 8 Earth Cluster, 7 Earth Crystal and 1 other kind.

The chain crosses three disciplines — Blacksmith to Lv 80, Goldsmith 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: Beryllium Ore (4:00, 16:00) and Tungsten Ore (10:00, 22:00). 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.
