Miner's Workboots ★

Taken all the way down to base materials, one Miner's Workboots is 3 crafting steps deep and needs 4 intermediates — Darksteel Nugget ×1, Hippogryph Leather ×1, Undyed Felt ×1 and 1 other — which resolve to 7 distinct raw materials totalling 10 units, plus 18 crystals.

That bill outweighs 5,754 of the 13,602 recipes tracked here and 691 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 5 of those crystals go into the final step; the other 13 are burned by the intermediates, so the real crystal cost is 6 Earth Crystal, 5 Lightning Shard, 3 Fire Crystal and 2 other kinds.

The chain crosses four disciplines — Leatherworker to Lv 50, Blacksmith to Lv 50, Weaver to Lv 43 and Alchemist to Lv 25 — so no single class can finish it unaided.

4 of the 7 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.
