Rarefied Hallowed Ramie Doublet

Taken all the way down to base materials, one Rarefied Hallowed Ramie Doublet is 4 crafting steps deep and needs 8 intermediates — Hallowed Ramie Cloth ×2, Dhalmel Leather ×1, Opal ×1 and 5 others — which resolve to 8 distinct raw materials totalling 30 units, plus 54 crystals.

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

Only 10 of those crystals go into the final step; the other 44 are burned by the intermediates, so the real crystal cost is 23 Lightning Crystal, 15 Wind Crystal, 10 Water Crystal and 2 other kinds.

The chain crosses four disciplines — Weaver to Lv 58, Alchemist to Lv 56, Goldsmith to Lv 56 and Leatherworker to Lv 54 — so no single class can finish it unaided.

7 of the 8 raw materials come out of the ground, and one of them is time-gated: Abalathian Mistletoe (6:00, 18:00). 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.
