Chondrite Ingot

Nothing in this list is craftable in turn, so one Chondrite 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 467 of the 1,932 Blacksmith 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.

Chondrite Ingot is itself consumed by 210 further recipes, spanning seven of the eight crafting classes.
