Thavnairian Headdress ★

Taken all the way down to base materials, one Thavnairian Headdress is 3 crafting steps deep and needs 4 intermediates — Aurum Regis Nugget ×1, Crawler Silk ×1, Larimar ×1 and 1 other — which resolve to 9 distinct raw materials totalling 19 units, plus 22 crystals.

That bill outweighs 7,589 of the 13,602 recipes tracked here and 977 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 19 are burned by the intermediates, so the real crystal cost is 9 Wind Crystal, 5 Lightning Crystal, 5 Wind Shard and 2 other kinds.

The chain crosses two disciplines — Weaver to Lv 60 and Goldsmith to Lv 58 — so no single class can finish it unaided.

6 of the 9 raw materials come out of the ground, and 2 of them are time-gated: Gold Ore (9:00) and Silkworm Cocoon (1:00). The widest gap between consecutive opening times is 16 Eorzean hours, about 47 real-world minutes.

Of the intermediates, Aurum Regis Nugget has the widest use: 185 recipes call for it, spanning seven of the eight crafting classes.
