Hammermaster's Workboots ★★

Taken all the way down to base materials, one Hammermaster's Workboots is 3 crafting steps deep and needs 5 intermediates — Griffin Leather ×3, Adamantite Nugget ×2, Adamantite Rivets ×1 and 2 others — which resolve to 11 distinct raw materials totalling 36 units, plus 32 crystals.

That bill outweighs 11,383 of the 13,602 recipes tracked here and 1,681 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 28 are burned by the intermediates, so the real crystal cost is 15 Fire Crystal, 9 Wind Crystal, 4 Earth Cluster and 1 other kind.

The chain crosses three disciplines — Leatherworker to Lv 60, Blacksmith to Lv 58 and Goldsmith to Lv 56 — so no single class can finish it unaided.

7 of the 11 raw materials come out of the ground, and 4 of them are time-gated: Adamantite Ore (0:00, 2:00, 6:00, 10:00, 12:00, 14:00, 18:00, 22:00), Red Alumen (10:00, 22:00) and 2 others. The widest gap between consecutive opening times is 4 Eorzean hours, about 12 real-world minutes.

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