Arachne Robe ★★★★

Taken all the way down to base materials, one Arachne Robe is 2 crafting steps deep and needs 5 intermediates — Arachne Velveteen ×5, Iolite ×1, Platinum Nugget ×1 and 2 others — which resolve to 9 distinct raw materials totalling 22 units, plus 36 crystals.

That bill outweighs 8,402 of the 13,602 recipes tracked here and 1,106 of the 1,968 Weaver ones, and 4,464 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 32 are burned by the intermediates, so the real crystal cost is 16 Wind Cluster, 12 Lightning Cluster, 3 Lightning Crystal and 2 other kinds.

The chain crosses two disciplines — Weaver to Lv 50 and Goldsmith to Lv 50 — so no single class can finish it unaided.

6 of the 9 raw materials come out of the ground, and 4 of them are time-gated: Gold Ore (9:00), Platinum Ore (4:00) and 2 others. The widest gap between consecutive opening times is 16 Eorzean hours, about 47 real-world minutes.

Of the intermediates, Rose Gold Nugget has the widest use: 179 recipes call for it, spanning seven of the eight crafting classes.
