Forager's Vest ★★★★

Taken all the way down to base materials, one Forager's Vest is 3 crafting steps deep and needs 3 intermediates — Platinum Nugget ×1, Vanya Silk ×1 and Silk Thread ×4 — which resolve to 6 distinct raw materials totalling 22 units, plus 14 crystals.

That bill outweighs 8,402 of the 13,602 recipes tracked here and 1,106 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 10 are burned by the intermediates, so the real crystal cost is 6 Lightning Crystal, 4 Wind Cluster, 3 Lightning Cluster and 1 other kind.

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

3 of the 6 raw materials come out of the ground, and 2 of them are time-gated: Platinum Ore (4:00) and Silkworm Cocoon (1:00). The widest gap between consecutive opening times is 21 Eorzean hours, about 61 real-world minutes.

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