Hallowed Ramie Doublet of Healing

Taken all the way down to base materials, one Hallowed Ramie Doublet of Healing is 4 crafting steps deep and needs 9 intermediates — Hallowed Ramie Cloth ×3, Grade 1 Mind Dissolvent ×2, Dhalmel Leather ×1 and 6 others — which resolve to 11 distinct raw materials totalling 44 units, plus 68 crystals.

That bill outweighs 12,337 of the 13,602 recipes tracked here and 1,802 of the 1,968 Weaver ones, and 1 recipe nests deeper.

Only 9 of those crystals go into the final step; the other 59 are burned by the intermediates, so the real crystal cost is 32 Lightning Crystal, 14 Water Crystal, 14 Wind Crystal and 2 other kinds.

The chain crosses four disciplines — Weaver to Lv 57, Alchemist to Lv 56, Goldsmith to Lv 56 and Leatherworker to Lv 54 — so no single class can finish it unaided.

9 of the 11 raw materials come out of the ground, and 2 of them are time-gated: Abalathian Mistletoe (6:00, 18:00) and Volcanic Rock Salt (17:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Dhalmel Leather has the widest use: 106 recipes call for it, spanning seven of the eight crafting classes.
