Koppranickel Rapier

Taken all the way down to base materials, one Koppranickel Rapier is 3 crafting steps deep and needs 4 intermediates — Koppranickel Ingot ×3, Titanium Nugget ×2, Larch Lumber ×1 and 1 other — which resolve to 7 distinct raw materials totalling 45 units, plus 36 crystals.

That bill outweighs 12,451 of the 13,602 recipes tracked here and 1,996 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 7 of those crystals go into the final step; the other 29 are burned by the intermediates, so the real crystal cost is 25 Wind Crystal and 11 Fire Crystal.

The chain crosses three disciplines — Goldsmith to Lv 63, Carpenter to Lv 62 and Blacksmith to Lv 54 — so no single class can finish it unaided.

All 7 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, Koppranickel Nugget has the widest use: 124 recipes call for it, spanning seven of the eight crafting classes.
