Ironworks Gloves of Gathering ★★★

Taken all the way down to base materials, one Ironworks Gloves of Gathering is 3 crafting steps deep and needs 4 intermediates — Eikon Leather ×2, Luminous Fiber ×2, High Mythrite Ingot ×1 and 1 other — which resolve to 12 distinct raw materials totalling 30 units, plus 32 crystals.

That bill outweighs 10,368 of the 13,602 recipes tracked here and 1,521 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 27 are burned by the intermediates, so the real crystal cost is 11 Earth Cluster, 6 Lightning Cluster, 6 Water Cluster and 2 other kinds.

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

6 of the 12 raw materials come out of the ground, and 4 of them are time-gated: Crystallized Sap (8:00, 20:00), Lumythrite Ore (2:00, 14:00) and 2 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.
