Ironworks Slops of Gathering ★★★

Taken all the way down to base materials, one Ironworks Slops of Gathering is 3 crafting steps deep and needs 5 intermediates — Luminous Fiber ×2, Eikon Cloth ×1, Eikon Leather ×1 and 2 others — which resolve to 14 distinct raw materials totalling 29 units, plus 28 crystals.

That bill outweighs 10,170 of the 13,602 recipes tracked here and 1,376 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 23 are burned by the intermediates, so the real crystal cost is 10 Lightning Cluster, 6 Wind Cluster, 5 Earth Cluster and 2 other kinds.

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

8 of the 14 raw materials come out of the ground, and 5 of them are time-gated: Crystallized Sap (8:00, 20:00), Frost Cotton Boll (6:00, 18:00) and 3 others. The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, High Mythrite Ingot has the widest use: 150 recipes call for it, spanning seven of the eight crafting classes.
