Dead Hive Codex ★★

Taken all the way down to base materials, one Dead Hive Codex is 2 crafting steps deep and needs 4 intermediates — Eikon Iron Ingot ×2, High Mythrite Ingot ×2, Enchanted Aurum Regis Ink ×1 and 1 other — which resolve to 14 distinct raw materials totalling 50 units, plus 34 crystals.

That bill outweighs 12,777 of the 13,602 recipes tracked here and 1,532 of the 1,591 Alchemist ones, and 4,464 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 30 are burned by the intermediates, so the real crystal cost is 12 Fire Cluster, 9 Wind Cluster, 6 Earth Cluster and 2 other kinds.

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

7 of the 14 raw materials come out of the ground, and 3 of them are time-gated: Lumythrite Ore (2:00, 14:00), Old-growth Camphorwood Log (8:00, 20:00) and 1 other. The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, High Mythrite Ingot has the widest use: 150 recipes call for it, spanning seven of the eight crafting classes.
