Weaver's Swallowtail ★

Taken all the way down to base materials, one Weaver's Swallowtail is 3 crafting steps deep and needs 5 intermediates — Undyed Woolen Cloth ×2, Hippogryph Leather ×1, Rose Gold Nugget ×1 and 2 others — which resolve to 7 distinct raw materials totalling 13 units, plus 24 crystals.

That bill outweighs 6,426 of the 13,602 recipes tracked here and 799 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 19 are burned by the intermediates, so the real crystal cost is 10 Lightning Shard, 6 Lightning Crystal, 5 Wind Crystal and 1 other kind.

The chain crosses three disciplines — Weaver to Lv 50, Goldsmith to Lv 50 and Leatherworker to Lv 50 — so no single class can finish it unaided.

5 of the 7 raw materials come out of the ground, and 2 of them are time-gated: Gold Ore (9:00) and Silkworm Cocoon (1:00). The widest gap between consecutive opening times is 16 Eorzean hours, about 47 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.
