Serge Turban of Gathering

Taken all the way down to base materials, one Serge Turban of Gathering is 4 crafting steps deep and needs 6 intermediates — Steppe Serge ×2, Azurite ×1, Durium Ingot ×1 and 3 others — which resolve to 9 distinct raw materials totalling 31 units, plus 41 crystals.

That bill outweighs 10,578 of the 13,602 recipes tracked here and 1,468 of the 1,968 Weaver ones, and 1 recipe nests deeper.

Only 9 of those crystals go into the final step; the other 32 are burned by the intermediates, so the real crystal cost is 18 Wind Crystal, 17 Lightning Crystal and 6 Water Shard.

The chain crosses three disciplines — Weaver to Lv 67, Goldsmith to Lv 66 and Alchemist to Lv 25 — so no single class can finish it unaided.

7 of the 9 raw materials come out of the ground, and one of them is time-gated: Raw Azurite (4:00, 16:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Durium Nugget has the widest use: 142 recipes call for it, spanning seven of the eight crafting classes.
