Southern Seas Skirt ★★★

Taken all the way down to base materials, one Southern Seas Skirt is 3 crafting steps deep and needs 3 intermediates — Duskcourt Cloth ×3, Dwarven Cotton ×1 and Dwarven Cotton Thread ×3 — which resolve to 4 distinct raw materials totalling 24 units, plus 33 crystals.

That bill outweighs 8,926 of the 13,602 recipes tracked here and 1,178 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 14 of those crystals go into the final step; the other 19 are burned by the intermediates, so the real crystal cost is 14 Lightning Crystal, 7 Wind Crystal, 6 Lightning Cluster and 1 other kind.

Every step is Weaver work, from a Lv 78 intermediate up to the Lv 80 finish, so one class covers the whole chain.

2 of the 4 raw materials come out of the ground, and one of them is time-gated: Duskblooms (4:00, 16:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Dwarven Cotton has the widest use: 165 recipes call for it, spanning eight of the eight crafting classes.
