Chromite Knuckles ★★

Taken all the way down to base materials, one Chromite Knuckles is 3 crafting steps deep and needs 6 intermediates — Grade 2 Reisui of Strength ×3, Chromite Ingot ×2, Palladium Ingot ×1 and 3 others — which resolve to 15 distinct raw materials totalling 48 units, plus 39 crystals.

That bill outweighs 12,691 of the 13,602 recipes tracked here and 1,712 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 35 are burned by the intermediates, so the real crystal cost is 10 Fire Crystal, 8 Fire Cluster, 6 Earth Cluster and 5 other kinds.

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

10 of the 15 raw materials come out of the ground, and 4 of them are time-gated: Chromite Ore (10:00, 22:00), Hallowed Basil (6:00, 18:00) and 2 others. The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, Palladium Nugget has the widest use: 129 recipes call for it, spanning seven of the eight crafting classes.
