Spring Skirt ★★★

Taken all the way down to base materials, one Spring Skirt is 3 crafting steps deep and needs 2 intermediates — Vanya Silk ×1 and Silk Thread ×3 — which resolve to 4 distinct raw materials totalling 17 units, plus 10 crystals.

That bill outweighs 7,161 of the 13,602 recipes tracked here and 916 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 7 are burned by the intermediates, so the real crystal cost is 6 Lightning Crystal, 3 Lightning Cluster and 1 Wind Cluster.

Every step is Weaver work, from a Lv 50 intermediate up to the Lv 50 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: Silkworm Cocoon (1:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Silk Thread has the widest use: 175 recipes call for it, spanning six of the eight crafting classes.
