Codex of the Round ★★★

Taken all the way down to base materials, one Codex of the Round is 2 crafting steps deep and needs 5 intermediates — Eikon Iron Ingot ×3, Luminous Fiber ×3, Platinum Ingot ×3 and 2 others — which resolve to 15 distinct raw materials totalling 76 units, plus 46 crystals.

That bill outweighs 13,379 of the 13,602 recipes tracked here and 1,566 of the 1,591 Alchemist ones, and 4,464 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 41 are burned by the intermediates, so the real crystal cost is 18 Wind Cluster, 12 Fire Cluster, 8 Water Cluster and 2 other kinds.

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

6 of the 15 raw materials come out of the ground, and 5 of them are time-gated: Crystallized Sap (8:00, 20:00), Meteorite (8:00, 20:00) and 3 others. The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Platinum Ingot has the widest use: 176 recipes call for it, spanning seven of the eight crafting classes.
