Arachne Bandana of Striking ★★★★

Taken all the way down to base materials, one Arachne Bandana of Striking is 2 crafting steps deep and needs 3 intermediates — Arachne Velveteen ×3, Emerald ×1 and Platinum Nugget ×1 — which resolve to 6 distinct raw materials totalling 12 units, plus 22 crystals.

That bill outweighs 6,221 of the 13,602 recipes tracked here and 768 of the 1,968 Weaver ones, and 4,464 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 18 are burned by the intermediates, so the real crystal cost is 12 Wind Cluster, 8 Lightning Cluster and 2 Fire Cluster.

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

2 of the 6 raw materials come out of the ground, and 2 of them are time-gated: Platinum Ore (4:00) and Raw Emerald (4:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Arachne Velveteen has the widest use: 60 recipes call for it, spanning four of the eight crafting classes.
