Sandteak Spinning Wheel

Taken all the way down to base materials, one Sandteak Spinning Wheel is 2 crafting steps deep and needs 2 intermediates — Sandteak Lumber ×3 and Titanbronze Nugget ×1 — which resolve to 3 distinct raw materials totalling 17 units, plus 42 crystals.

That bill outweighs 7,161 of the 13,602 recipes tracked here and 692 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 14 of those crystals go into the final step; the other 28 are burned by the intermediates, so the real crystal cost is 35 Wind Crystal and 7 Ice Crystal.

The chain crosses two disciplines — Carpenter to Lv 77 and Goldsmith to Lv 76 — 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, Titanbronze Nugget has the widest use: 72 recipes call for it, spanning seven of the eight crafting classes.
