Dark Mahogany Grinding Wheel

Taken all the way down to base materials, one Dark Mahogany Grinding Wheel is 3 crafting steps deep and needs 3 intermediates — Dark Mahogany Lumber ×3, Pink Beryl ×1 and Annite Whetstone ×1 — which resolve to 3 distinct raw materials totalling 22 units, plus 55 crystals.

That bill outweighs 8,402 of the 13,602 recipes tracked here and 849 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 15 of those crystals go into the final step; the other 40 are burned by the intermediates, so the real crystal cost is 48 Wind Crystal and 7 Ice Crystal.

The chain crosses two disciplines — Carpenter to Lv 94 and Goldsmith to Lv 94 — 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, Annite Whetstone has the widest use: 96 recipes call for it, spanning four of the eight crafting classes.
