Archeo Kingdom Broadsword ★★

Taken all the way down to base materials, one Archeo Kingdom Broadsword is 2 crafting steps deep and needs 3 intermediates — Maraging Steel Ingot ×3, Grade 2 Gemsap of Vitality ×1 and Ra'Kaznar Ingot ×1 — which resolve to 9 distinct raw materials totalling 29 units, plus 38 crystals.

That bill outweighs 10,170 of the 13,602 recipes tracked here and 1,176 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 32 are burned by the intermediates, so the real crystal cost is 12 Earth Cluster, 12 Fire Cluster, 8 Fire Crystal and 2 other kinds.

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

6 of the 9 raw materials come out of the ground, and 2 of them are time-gated: Harmonite Ore (6:00, 18:00) and Nopaliflower (2:00, 14:00). The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

Of the intermediates, Ra'Kaznar Ingot has the widest use: 166 recipes call for it, spanning seven of the eight crafting classes.
