Claro Walnut Spinning Wheel

Taken all the way down to base materials, one Claro Walnut Spinning Wheel is 3 crafting steps deep and needs 3 intermediates — Black Star ×2, Claro Walnut Lumber ×2 and Magnesia Whetstone ×3 — which resolve to 3 distinct raw materials totalling 28 units, plus 72 crystals.

That bill outweighs 9,936 of the 13,602 recipes tracked here and 1,019 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 16 of those crystals go into the final step; the other 56 are burned by the intermediates, so the real crystal cost is 40 Wind Crystal, 24 Water Crystal and 8 Ice Crystal.

The chain crosses three disciplines — Carpenter to Lv 99, Goldsmith to Lv 98 and Alchemist to Lv 95 — so no single class can finish it unaided.

All 3 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, Black Star has the widest use: 161 recipes call for it, spanning six of the eight crafting classes.
