Gemmaster's Sandals ★★

Taken all the way down to base materials, one Gemmaster's Sandals is 3 crafting steps deep and needs 5 intermediates — Griffin Leather ×3, Larimar ×2, Hardsilver Ingot ×1 and 2 others — which resolve to 12 distinct raw materials totalling 33 units, plus 35 crystals.

That bill outweighs 10,907 of the 13,602 recipes tracked here and 1,636 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 31 are burned by the intermediates, so the real crystal cost is 17 Wind Crystal, 10 Wind Shard, 4 Earth Cluster and 1 other kind.

The chain crosses two disciplines — Leatherworker to Lv 60 and Goldsmith to Lv 56 — so no single class can finish it unaided.

7 of the 12 raw materials come out of the ground, and 2 of them are time-gated: Red Alumen (10:00, 22:00) and Wattle Bark (2:00, 14:00). The widest gap between consecutive opening times is 8 Eorzean hours, about 23 real-world minutes.

Of the intermediates, Hardsilver Ingot has the widest use: 117 recipes call for it, spanning seven of the eight crafting classes.
