Cloud Mica Grinding Wheel

Taken all the way down to base materials, one Cloud Mica Grinding Wheel is 2 crafting steps deep and needs 3 intermediates — Cloud Mica Whetstone ×2, Dark Chestnut Lumber ×2 and Hardsilver Nugget ×1 — which resolve to 4 distinct raw materials totalling 22 units, plus 31 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 9 of those crystals go into the final step; the other 22 are burned by the intermediates, so the real crystal cost is 27 Wind Crystal and 4 Ice Crystal.

The chain crosses two disciplines — Carpenter to Lv 56 and Goldsmith to Lv 56 — so no single class can finish it unaided.

All 4 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, Hardsilver Nugget has the widest use: 88 recipes call for it, spanning seven of the eight crafting classes.
