Great Gubal Floor Lamp ★★

Taken all the way down to base materials, one Great Gubal Floor Lamp is 3 crafting steps deep and needs 4 intermediates — Adamantite Ingot ×2, Aurum Regis Ingot ×1, Adamantite Nugget ×2 and 1 other — which resolve to 12 distinct raw materials totalling 37 units, plus 27 crystals.

That bill outweighs 11,564 of the 13,602 recipes tracked here and 1,403 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 23 are burned by the intermediates, so the real crystal cost is 10 Fire Crystal, 6 Fire Cluster, 5 Wind Crystal and 2 other kinds.

The chain crosses two disciplines — Blacksmith to Lv 60 and Goldsmith to Lv 60 — so no single class can finish it unaided.

8 of the 12 raw materials come out of the ground, and 7 of them are time-gated: Adamantite Ore (0:00, 2:00, 6:00, 10:00, 12:00, 14:00, 18:00, 22:00), Aurum Regis Ore (2:00, 14:00) and 5 others. The widest gap between consecutive opening times is 4 Eorzean hours, about 12 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.
