Pewter Ingot

Nothing in this list is craftable in turn, so one Pewter Ingot is a single step: 6 units of material drawn from 2 base items, plus 8 crystals.

That bill outweighs 4,542 of the 13,602 recipes tracked here and 643 of the 2,216 Goldsmith ones, and 9,374 recipes nest deeper.

Both raw materials are gathered, and no spot for either is timed, so nothing in the tree waits on the Eorzean clock.

Pewter Ingot is itself consumed by 63 further recipes, spanning six of the eight crafting classes.
