Facet Hat of Healing ★★

Taken all the way down to base materials, one Facet Hat of Healing is 3 crafting steps deep and needs 5 intermediates — Ethereal Silk ×2, Grade 2 Mind Alkahest ×2, Chalicotherium Leather ×1 and 2 others — which resolve to 8 distinct raw materials totalling 28 units, plus 27 crystals.

That bill outweighs 9,936 of the 13,602 recipes tracked here and 1,333 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 23 are burned by the intermediates, so the real crystal cost is 8 Lightning Cluster, 8 Wind Cluster, 7 Lightning 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 8 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, Dwarven Cotton has the widest use: 165 recipes call for it, spanning eight of the eight crafting classes.
