Sky Pirate's Cap of Healing ★★

Taken all the way down to base materials, one Sky Pirate's Cap of Healing is 3 crafting steps deep and needs 6 intermediates — Crystal Glass ×2, Grade 1 Mind Dissolvent ×1, Pterodactyl Leather ×1 and 3 others — which resolve to 14 distinct raw materials totaling 31 units, plus 32 crystals.

That bill outweighs 10,578 of the 13,602 recipes tracked here and 1,713 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 28 are burned by the intermediates, so the real crystal cost is 14 Water Crystal, 4 Fire Cluster, 4 Fire Crystal and 3 other kinds.

The chain crosses four disciplines — Goldsmith to Lv 60, Blacksmith to Lv 60, Leatherworker to Lv 60 and Alchemist to Lv 54 — so no single class can finish it unaided.

9 of the 14 raw materials come out of the ground, and one of them is time-gated: Volcanic Rock Salt (17:00). That window comes around once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Titanium Nugget has the widest use: 112 recipes call for it, spanning six of the eight crafting classes.
