Ironworks Cap of Gathering ★★★

Taken all the way down to base materials, one Ironworks Cap of Gathering is 3 crafting steps deep and needs 6 intermediates — Eikon Leather ×2, Luminous Fiber ×2, Crystal Glass ×1 and 3 others — which resolve to 16 distinct raw materials totalling 37 units, plus 39 crystals.

That bill outweighs 11,564 of the 13,602 recipes tracked here and 1,713 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 34 are burned by the intermediates, so the real crystal cost is 9 Earth Cluster, 9 Wind Cluster, 6 Lightning Cluster and 4 other kinds.

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

9 of the 16 raw materials come out of the ground, and 4 of them are time-gated: Crystallized Sap (8:00, 20:00), Meteorite (8:00, 20:00) and 2 others. The widest gap between consecutive opening times is 6 Eorzean hours, about 18 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.
