Acacia Grinding Wheel

Taken all the way down to base materials, one Acacia Grinding Wheel is 2 crafting steps deep and needs 2 intermediates — Acacia Lumber ×2 and White Gold Ingot ×2 — which resolve to 3 distinct raw materials totalling 22 units, plus 48 crystals.

That bill outweighs 8,402 of the 13,602 recipes tracked here and 849 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 16 of those crystals go into the final step; the other 32 are burned by the intermediates, so the real crystal cost is 40 Wind Crystal and 8 Ice Crystal.

The chain crosses two disciplines — Carpenter to Lv 97 and Goldsmith to Lv 96 — 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, White Gold Ingot has the widest use: 121 recipes call for it, spanning seven of the eight crafting classes.
