Miner's Shirt ★

Taken all the way down to base materials, one Miner's Shirt is 3 crafting steps deep and needs 6 intermediates — Hippogryph Leather ×2, Undyed Felt ×2, Brass Ingot ×1 and 3 others — which resolve to 9 distinct raw materials totalling 22 units, plus 31 crystals.

That bill outweighs 8,402 of the 13,602 recipes tracked here and 1,157 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 26 are burned by the intermediates, so the real crystal cost is 12 Lightning Shard, 9 Earth Crystal, 4 Water Shard and 3 other kinds.

The chain crosses four disciplines — Leatherworker to Lv 50, Weaver to Lv 50, Alchemist to Lv 25 and Goldsmith to Lv 14 — so no single class can finish it unaided.

6 of the 9 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.
