Indagator's Doublet Vest of Gathering ★★★

Taken all the way down to base materials, one Indagator's Doublet Vest of Gathering is 2 crafting steps deep and needs 3 intermediates — Bayberry Cloth ×4, Craftsman's Alkahest ×4 and Ilmenite Ingot ×3 — which resolve to 8 distinct raw materials totalling 77 units, plus 76 crystals.

That bill outweighs 13,389 of the 13,602 recipes tracked here and 1,948 of the 1,968 Weaver ones, and 4,464 recipes nest deeper.

Only 10 of those crystals go into the final step; the other 66 are burned by the intermediates, so the real crystal cost is 29 Lightning Cluster, 17 Wind Cluster, 12 Water Cluster and 2 other kinds.

The chain crosses three disciplines — Weaver to Lv 90, Alchemist to Lv 90 and Blacksmith to Lv 90 — so no single class can finish it unaided.

3 of the 8 raw materials come out of the ground, and 3 of them are time-gated: Bayberry (4:00, 16:00), Ilmenite (8:00, 20:00) and 1 other. The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

Of the intermediates, Ilmenite Ingot has the widest use: 73 recipes call for it, spanning six of the eight crafting classes.
