Ironworks Tool Set

Taken all the way down to base materials, one Ironworks Tool Set is 2 crafting steps deep and needs 3 intermediates — Eikon Iron Ingot ×4, Manganese Ingot ×4 and High Durium Ingot ×2 — which resolve to 7 distinct raw materials totalling 68 units, plus 84 crystals.

That bill outweighs 13,264 of the 13,602 recipes tracked here and 1,862 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 16 of those crystals go into the final step; the other 68 are burned by the intermediates, so the real crystal cost is 56 Fire Crystal, 12 Wind Cluster, 8 Earth Crystal and 1 other kind.

The chain crosses two disciplines — Blacksmith to Lv 90 and Goldsmith to Lv 60 — so no single class can finish it unaided.

6 of the 7 raw materials come out of the ground, and one of them is time-gated: Smithsonite Ore (8:00, 20:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Eikon Iron Ingot has the widest use: 140 recipes call for it, spanning seven of the eight crafting classes.
