Archeo Kingdom Claymore ★★

Taken all the way down to base materials, one Archeo Kingdom Claymore is 3 crafting steps deep and needs 5 intermediates — Maraging Steel Ingot ×3, Blackseed Cotton Cloth ×2, Grade 2 Gemsap of Vitality ×2 and 2 others — which resolve to 11 distinct raw materials totalling 42 units, plus 58 crystals.

That bill outweighs 12,044 of the 13,602 recipes tracked here and 1,501 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 52 are burned by the intermediates, so the real crystal cost is 12 Earth Cluster, 12 Fire Cluster, 9 Lightning Cluster and 4 other kinds.

The chain crosses four disciplines — Blacksmith to Lv 100, Alchemist to Lv 100, Weaver to Lv 100 and Goldsmith to Lv 98 — so no single class can finish it unaided.

7 of the 11 raw materials come out of the ground, and 3 of them are time-gated: Blackseed Cotton Boll (4:00, 16:00), Harmonite Ore (6:00, 18:00) and 1 other. The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

Of the intermediates, Black Star has the widest use: 161 recipes call for it, spanning six of the eight crafting classes.
