Blacksmith's Goggles ★

Taken all the way down to base materials, one Blacksmith's Goggles is 3 crafting steps deep and needs 6 intermediates — Clear Glass Lens ×1, Darksteel Nugget ×1, Hippogryph Leather ×1 and 3 others — which resolve to 7 distinct raw materials totalling 10 units, plus 21 crystals.

That bill outweighs 5,754 of the 13,602 recipes tracked here and 801 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 16 are burned by the intermediates, so the real crystal cost is 5 Fire Crystal, 5 Lightning Shard, 5 Water Shard and 2 other kinds.

The chain crosses five disciplines — Goldsmith to Lv 50, Blacksmith to Lv 50, Leatherworker to Lv 50, Weaver to Lv 39 and Alchemist to Lv 28 — so no single class can finish it unaided.

5 of the 7 raw materials come out of the ground, and one of them is time-gated: Darksteel Ore (1:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Undyed Woolen Cloth has the widest use: 154 recipes call for it, spanning seven of the eight crafting classes.
