Artisan's Sandals ★★★★

Taken all the way down to base materials, one Artisan's Sandals is 3 crafting steps deep and needs 4 intermediates — Hippogryph Leather ×2, Platinum Nugget ×1, Treated Spruce Lumber ×1 and 1 other — which resolve to 7 distinct raw materials totalling 26 units, plus 20 crystals.

That bill outweighs 9,543 of the 13,602 recipes tracked here and 976 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 16 are burned by the intermediates, so the real crystal cost is 6 Earth Crystal, 6 Wind Crystal, 5 Wind Cluster and 2 other kinds.

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

3 of the 7 raw materials come out of the ground, and 2 of them are time-gated: Platinum Ore (4:00) and Spruce Log (9:00). The widest gap between consecutive opening times is 19 Eorzean hours, about 55 real-world minutes.

Of the intermediates, Hippogryph Leather has the widest use: 131 recipes call for it, spanning seven of the eight crafting classes.
