Archeo Kingdom Index ★★

Taken all the way down to base materials, one Archeo Kingdom Index is 2 crafting steps deep and needs 4 intermediates — Maraging Steel Ingot ×3, Grade 2 Gemsap of Intelligence ×2, Ipe Lumber ×2 and 1 other — which resolve to 13 distinct raw materials totalling 40 units, plus 50 crystals.

That bill outweighs 11,825 of the 13,602 recipes tracked here and 1,466 of the 1,591 Alchemist ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 44 are burned by the intermediates, so the real crystal cost is 9 Earth Cluster, 9 Fire Cluster, 8 Water Crystal and 4 other kinds.

The chain crosses three disciplines — Alchemist to Lv 100, Blacksmith to Lv 100 and Carpenter to Lv 100 — so no single class can finish it unaided.

8 of the 13 raw materials come out of the ground, and 3 of them are time-gated: Harmonite Ore (6:00, 18:00), Ipe Log (0:00, 12:00) and 1 other. The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, Maraging Steel Ingot has the widest use: 46 recipes call for it, spanning five of the eight crafting classes.
