Facet Trousers of Healing ★★

Taken all the way down to base materials, one Facet Trousers of Healing is 2 crafting steps deep and needs 4 intermediates — Chalicotherium Leather ×2, Ethereal Silk ×2, Grade 2 Mind Alkahest ×2 and 1 other — which resolve to 9 distinct raw materials totalling 35 units, plus 31 crystals.

That bill outweighs 11,223 of the 13,602 recipes tracked here and 1,597 of the 1,968 Weaver ones, and 4,464 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 10 Wind Cluster, 8 Lightning Cluster, 7 Earth Crystal and 2 other kinds.

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

3 of the 9 raw materials come out of the ground, and one of them is time-gated: Ethereal Cocoon (8:00, 20:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Zonure Leather has the widest use: 55 recipes call for it, spanning seven of the eight crafting classes.
