Forgemaster's Goggles ★★

Taken all the way down to base materials, one Forgemaster's Goggles is 3 crafting steps deep and needs 7 intermediates — Astral Silk ×2, Crystal Glass ×2, Aurum Regis Ingot ×1 and 4 others — which resolve to 17 distinct raw materials totalling 53 units, plus 44 crystals.

That bill outweighs 12,925 of the 13,602 recipes tracked here and 2,088 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 40 are burned by the intermediates, so the real crystal cost is 10 Lightning Crystal, 10 Water Crystal, 6 Wind Cluster and 5 other kinds.

The chain crosses three disciplines — Goldsmith to Lv 60, Alchemist to Lv 60 and Weaver to Lv 60 — so no single class can finish it unaided.

10 of the 17 raw materials come out of the ground, and 6 of them are time-gated: Astral Moraine (0:00, 12:00), Aurum Regis Ore (2:00, 14:00) and 4 others. The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

Of the intermediates, Aurum Regis Nugget has the widest use: 185 recipes call for it, spanning seven of the eight crafting classes.
