Archeo Kingdom Scutum ★★

Taken all the way down to base materials, one Archeo Kingdom Scutum is 2 crafting steps deep and needs 3 intermediates — Grade 2 Gemsap of Vitality ×1, Ipe Lumber ×1 and Maraging Steel Ingot ×1 — which resolve to 8 distinct raw materials totalling 16 units, plus 24 crystals.

That bill outweighs 6,959 of the 13,602 recipes tracked here and 642 of the 1,441 Armorer ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 18 are burned by the intermediates, so the real crystal cost is 6 Earth Cluster, 6 Ice Cluster, 3 Fire Cluster and 3 other kinds.

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

5 of the 8 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.
