Ironworks Armillae of Crafting ★★★

Taken all the way down to base materials, one Ironworks Armillae of Crafting is 3 crafting steps deep and needs 5 intermediates — Celestine ×2, Eikon Leather ×1, Luminous Fiber ×1 and 2 others — which resolve to 13 distinct raw materials totalling 44 units, plus 27 crystals.

That bill outweighs 12,337 of the 13,602 recipes tracked here and 1,302 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 22 are burned by the intermediates, so the real crystal cost is 10 Wind Cluster, 4 Ice Cluster, 4 Lightning Cluster and 3 other kinds.

The chain crosses four disciplines — Carpenter to Lv 60, Alchemist to Lv 60, Leatherworker to Lv 60 and Goldsmith to Lv 54 — so no single class can finish it unaided.

5 of the 13 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, Treated Camphorwood Lumber has the widest use: 92 recipes call for it, spanning five of the eight crafting classes.
