Blacksmith's Workboots ★

Taken all the way down to base materials, one Blacksmith's Workboots is 2 crafting steps deep and needs 2 intermediates — Darksteel Nugget ×1 and Hippogryph Leather ×1 — which resolve to 4 distinct raw materials totalling 6 units, plus 11 crystals.

That bill outweighs 4,542 of the 13,602 recipes tracked here and 466 of the 1,441 Armorer ones, and 4,464 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 6 are burned by the intermediates, so the real crystal cost is 5 Earth Crystal, 3 Fire Crystal and 3 Ice Crystal.

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

2 of the 4 raw materials come out of the ground, and one of them is time-gated: Darksteel Ore (1:00). That window comes round once per Eorzean day, every 70 real-world minutes.

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