Kirimu Boots of Aiming ★★★★

Taken all the way down to base materials, one Kirimu Boots of Aiming is 2 crafting steps deep and needs 4 intermediates — Kirimu Leather ×3, Platinum Nugget ×1, Saurian Leather ×1 and 1 other — which resolve to 7 distinct raw materials totalling 14 units, plus 25 crystals.

That bill outweighs 6,557 of the 13,602 recipes tracked here and 807 of the 1,844 Leatherworker ones, and 4,464 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 21 are burned by the intermediates, so the real crystal cost is 11 Wind Cluster, 10 Earth Cluster, 3 Lightning Crystal and 1 other kind.

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

4 of the 7 raw materials come out of the ground, and 3 of them are time-gated: Platinum Ore (4:00), Shroud Tea Leaves (2:00) and 1 other. The widest gap between consecutive opening times is 21 Eorzean hours, about 61 real-world minutes.

Of the intermediates, Silk Thread has the widest use: 175 recipes call for it, spanning six of the eight crafting classes.
