Everseeker's Goggles of Gathering ★★

Taken all the way down to base materials, one Everseeker's Goggles of Gathering is 3 crafting steps deep and needs 5 intermediates — Alexandrian Plate ×2, Sterling Silver Ingot ×2, Black Star ×1 and 2 others — which resolve to 9 distinct raw materials totalling 39 units, plus 52 crystals.

That bill outweighs 11,756 of the 13,602 recipes tracked here and 1,892 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 46 are burned by the intermediates, so the real crystal cost is 9 Fire Cluster, 9 Wind Cluster, 8 Water Crystal and 5 other kinds.

The chain crosses three disciplines — Goldsmith to Lv 100, Alchemist to Lv 100 and Armorer to Lv 100 — so no single class can finish it unaided.

5 of the 9 raw materials come out of the ground, and 3 of them are time-gated: Alexandrian Ore (6:00, 18:00), Fine Silver Ore (10:00, 22:00) and 1 other. The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, Black Star has the widest use: 161 recipes call for it, spanning six of the eight crafting classes.
