Pixie Cotton Robe of Healing

Taken all the way down to base materials, one Pixie Cotton Robe of Healing is 3 crafting steps deep and needs 7 intermediates — Grade 1 Mind Alkahest ×2, Pixie Cotton ×2, Atrociraptor Leather ×1 and 4 others — which resolve to 10 distinct raw materials totalling 30 units, plus 52 crystals.

That bill outweighs 10,368 of the 13,602 recipes tracked here and 1,408 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 13 of those crystals go into the final step; the other 39 are burned by the intermediates, so the real crystal cost is 30 Lightning Crystal, 9 Wind Crystal, 7 Earth Crystal and 1 other kind.

The chain crosses four disciplines — Weaver to Lv 75, Leatherworker to Lv 74, Alchemist to Lv 73 and Goldsmith to Lv 50 — so no single class can finish it unaided.

8 of the 10 raw materials come out of the ground, and one of them is time-gated: Gold Ore (9:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Rose Gold Nugget has the widest use: 179 recipes call for it, spanning seven of the eight crafting classes.
