Ramie Skirt

Taken all the way down to base materials, one Ramie Skirt is 4 crafting steps deep and needs 8 intermediates — Ramie Cloth ×3, Holy Rainbow Cloth ×1, Ramie Thread ×7 and 5 others — which resolve to 7 distinct raw materials totalling 35 units, plus 37 crystals.

That bill outweighs 11,223 of the 13,602 recipes tracked here and 1,597 of the 1,968 Weaver ones, and 1 recipe nests deeper.

Only 9 of those crystals go into the final step; the other 28 are burned by the intermediates, so the real crystal cost is 25 Lightning Crystal, 5 Lightning Shard, 4 Wind Crystal and 1 other kind.

The chain crosses two disciplines — Weaver to Lv 56 and Alchemist to Lv 52 — so no single class can finish it unaided.

6 of the 7 raw materials come out of the ground, and one of them is time-gated: Dravanian Mistletoe (0:00, 12:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Rainbow Thread has the widest use: 116 recipes call for it, spanning five of the eight crafting classes.
