Noble's Codex

Taken all the way down to base materials, one Noble's Codex is 3 crafting steps deep and needs 7 intermediates — Aurum Regis Nugget ×2, Hardsilver Ingot ×2, Chrysolite ×1 and 4 others — which resolve to 11 distinct raw materials totalling 49 units, plus 52 crystals.

That bill outweighs 12,749 of the 13,602 recipes tracked here and 1,528 of the 1,591 Alchemist ones, and 337 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 49 are burned by the intermediates, so the real crystal cost is 39 Wind Crystal, 5 Earth Crystal, 5 Water Crystal and 2 other kinds.

The chain crosses three disciplines — Alchemist to Lv 60, Goldsmith to Lv 60 and Leatherworker to Lv 56 — so no single class can finish it unaided.

9 of the 11 raw materials come out of the ground, and one of them is time-gated: Gold Ore (9:00). That window comes round once per Eorzean day, every 70 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.
