Platinum Ingot ★★★★

Nothing in this list is craftable in turn, so one Platinum Ingot is a single step: 11 units of material drawn from 2 base items, plus 4 crystals.

That bill outweighs 5,999 of the 13,602 recipes tracked here and 839 of the 2,216 Goldsmith ones, and 9,374 recipes nest deeper.

1 of the 2 raw materials come out of the ground, and one of them is time-gated: Platinum Ore (4:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Platinum Ingot is itself consumed by 176 further recipes, spanning seven of the eight crafting classes.
