Alchemist's Monocle ★

Taken all the way down to base materials, one Alchemist's Monocle is 3 crafting steps deep and needs 5 intermediates — Boar Leather ×1, Clear Glass Lens ×1, Darksteel Nugget ×1 and 2 others — which resolve to 8 distinct raw materials totalling 12 units, plus 20 crystals.

That bill outweighs 6,221 of the 13,602 recipes tracked here and 862 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 15 are burned by the intermediates, so the real crystal cost is 6 Wind Crystal, 5 Fire Crystal, 5 Water Shard and 1 other kind.

The chain crosses four disciplines — Goldsmith to Lv 50, Blacksmith to Lv 50, Leatherworker to Lv 33 and Alchemist to Lv 28 — so no single class can finish it unaided.

7 of the 8 raw materials come out of the ground, and 2 of them are time-gated: Darksteel Ore (1:00) and Gold Ore (9:00). The widest gap between consecutive opening times is 16 Eorzean hours, about 47 real-world minutes.

Of the intermediates, Rose Gold Nugget has the widest use: 179 recipes call for it, spanning seven of the eight crafting classes.
