Ironworks Cap of Crafting ★★★

Taken all the way down to base materials, one Ironworks Cap of Crafting is 2 crafting steps deep and needs 3 intermediates — Eikon Cloth ×2, Luminous Fiber ×2 and Eikon Iron Ingot ×1 — which resolve to 11 distinct raw materials totalling 29 units, plus 24 crystals.

That bill outweighs 10,170 of the 13,602 recipes tracked here and 1,376 of the 1,968 Weaver ones, and 4,464 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 19 are burned by the intermediates, so the real crystal cost is 11 Lightning Cluster, 9 Wind Cluster, 2 Fire Cluster and 1 other kind.

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

6 of the 11 raw materials come out of the ground, and 4 of them are time-gated: Crystallized Sap (8:00, 20:00), Frost Cotton Boll (6:00, 18:00) and 2 others. The widest gap between consecutive opening times is 10 Eorzean hours, about 29 real-world minutes.

Of the intermediates, Eikon Iron Ingot has the widest use: 140 recipes call for it, spanning seven of the eight crafting classes.
