Cantamina Thavnaria ★★

Taken all the way down to base materials, one Cantamina Thavnaria is 3 crafting steps deep and needs 4 intermediates — Enchanted Rose Gold Ink ×1, Hippogryph Leather ×1, Rose Gold Nugget ×1 and 1 other — which resolve to 8 distinct raw materials totalling 20 units, plus 12 crystals.

That bill outweighs 7,876 of the 13,602 recipes tracked here and 1,279 of the 1,591 Alchemist ones, and 337 recipes nest deeper.

Only 2 of those crystals go into the final step; the other 10 are burned by the intermediates, so the real crystal cost is 3 Earth Crystal, 3 Water Crystal, 3 Wind Crystal and 2 other kinds.

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

4 of the 8 raw materials come out of the ground, and 2 of them are time-gated: Gold Ore (9:00) and Gold Sand (5:00). The widest gap between consecutive opening times is 20 Eorzean hours, about 58 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.
