Arachne Shirt of Striking ★★★★

Taken all the way down to base materials, one Arachne Shirt of Striking is 2 crafting steps deep and needs 5 intermediates — Arachne Velveteen ×5, Hippogryph Leather ×1, Platinum Nugget ×1 and 2 others — which resolve to 9 distinct raw materials totalling 20 units, plus 36 crystals.

That bill outweighs 7,876 of the 13,602 recipes tracked here and 1,022 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 Earth Crystal and 2 other kinds.

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

5 of the 9 raw materials come out of the ground, and 3 of them are time-gated: Platinum Ore (4:00), Raw Topaz (3:00) and 1 other. The widest gap between consecutive opening times is 21 Eorzean hours, about 61 real-world minutes.

Of the intermediates, Silk Thread has the widest use: 175 recipes call for it, spanning six of the eight crafting classes.
