Leatherworker's Shirt ★

Taken all the way down to base materials, one Leatherworker's Shirt is 3 crafting steps deep and needs 4 intermediates — Hippogryph Leather ×2, Silk Thread ×1, Undyed Woolen Cloth ×1 and 1 other — which resolve to 5 distinct raw materials totalling 11 units, plus 21 crystals.

That bill outweighs 5,999 of the 13,602 recipes tracked here and 724 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 16 are burned by the intermediates, so the real crystal cost is 9 Earth Crystal, 7 Lightning Shard, 3 Lightning Crystal and 1 other kind.

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

3 of the 5 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.
