Gold Mechanical Voice Box

Taken all the way down to base materials, one Gold Mechanical Voice Box is 3 crafting steps deep and needs 4 intermediates — Phrygian Gold Ingot ×2, Chondrite Ingot ×1, Star Quartz ×1 and 1 other — which resolve to 6 distinct raw materials totalling 25 units, plus 56 crystals.

That bill outweighs 9,313 of the 13,602 recipes tracked here and 1,507 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 16 of those crystals go into the final step; the other 40 are burned by the intermediates, so the real crystal cost is 40 Wind Crystal and 16 Fire Crystal.

The chain crosses two disciplines — Goldsmith to Lv 88 and Blacksmith to Lv 88 — so no single class can finish it unaided.

All 6 raw materials are gathered, and not one of their spots is timed, so nothing in the tree waits on the Eorzean clock.

Of the intermediates, Chondrite Ingot has the widest use: 210 recipes call for it, spanning seven of the eight crafting classes.
