Eikon Iron Ingot ★★★

Nothing in this list is craftable in turn, so one Eikon Iron Ingot is a single step: 8 units of material drawn from 3 base items, plus 5 crystals.

That bill outweighs 5,254 of the 13,602 recipes tracked here and 742 of the 2,216 Goldsmith ones, and 9,374 recipes nest deeper.

2 of the 3 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.

Eikon Iron Ingot is itself consumed by 140 further recipes, spanning seven of the eight crafting classes.
