Slothskin Boots of Aiming ★★★

Taken all the way down to base materials, one Slothskin Boots of Aiming is 3 crafting steps deep and needs 5 intermediates — Ground Sloth Leather ×2, Grade 3 Reisui of Dexterity ×1, Silvergrace Ingot ×1 and 2 others — which resolve to 13 distinct raw materials totalling 29 units, plus 21 crystals.

That bill outweighs 10,170 of the 13,602 recipes tracked here and 1,478 of the 1,844 Leatherworker ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 17 are burned by the intermediates, so the real crystal cost is 6 Wind Cluster, 4 Earth Cluster, 3 Wind Crystal and 4 other kinds.

The chain crosses four disciplines — Leatherworker to Lv 70, Alchemist to Lv 70, Goldsmith to Lv 70 and Weaver to Lv 68 — so no single class can finish it unaided.

7 of the 13 raw materials come out of the ground, and 2 of them are time-gated: Gyr Abanian Spring Water (10:00, 22:00) and Silvergrace Ore (8:00, 20:00). The widest gap between consecutive opening times is 10 Eorzean hours, about 29 real-world minutes.

Of the intermediates, Koppranickel Nugget has the widest use: 124 recipes call for it, spanning seven of the eight crafting classes.
