Hamlet Cutter's Hat ★

Taken all the way down to base materials, one Hamlet Cutter's Hat is 3 crafting steps deep and needs 5 intermediates — Hippogryph Leather ×1, Silk Thread ×1, Silver Ingot ×1 and 2 others — which resolve to 6 distinct raw materials totalling 10 units, plus 18 crystals.

That bill outweighs 5,754 of the 13,602 recipes tracked here and 695 of the 1,968 Weaver ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 13 are burned by the intermediates, so the real crystal cost is 6 Lightning Crystal, 5 Lightning Shard, 3 Earth Crystal and 2 other kinds.

The chain crosses three disciplines — Weaver to Lv 50, Leatherworker to Lv 50 and Goldsmith to Lv 23 — so no single class can finish it unaided.

4 of the 6 raw materials come out of the ground, and one of them is time-gated: Silkworm Cocoon (1:00). That window comes round once per Eorzean day, every 70 real-world minutes.

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