Archaeoskin Codex

Taken all the way down to base materials, one Archaeoskin Codex is 2 crafting steps deep and needs 4 intermediates — Archaeornis Leather ×2, Electrum Ingot ×1, Enchanted Mythrite Ink ×1 and 1 other — which resolve to 7 distinct raw materials totalling 20 units, plus 22 crystals.

That bill outweighs 7,876 of the 13,602 recipes tracked here and 1,279 of the 1,591 Alchemist ones, and 4,464 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 17 are burned by the intermediates, so the real crystal cost is 9 Earth Crystal, 6 Water Crystal, 5 Wind Shard and 1 other kind.

The chain crosses three disciplines — Alchemist to Lv 51, Leatherworker to Lv 51 and Goldsmith to Lv 42 — so no single class can finish it unaided.

4 of the 7 raw materials come out of the ground, and one of them is time-gated: Coerthan Tea Leaves (0:00, 8:00, 10:00, 12:00, 20:00, 22:00). The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

Of the intermediates, Electrum Ingot has the widest use: 234 recipes call for it, spanning seven of the eight crafting classes.
