White Ash Grinding Wheel

Taken all the way down to base materials, one White Ash Grinding Wheel is 2 crafting steps deep and needs 3 intermediates — White Ash Lumber ×2, Bluespirit Tile ×1 and Hard Mudstone Whetstone ×1 — which resolve to 4 distinct raw materials totalling 16 units, plus 40 crystals.

That bill outweighs 6,959 of the 13,602 recipes tracked here and 675 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 13 of those crystals go into the final step; the other 27 are burned by the intermediates, so the real crystal cost is 27 Wind Crystal, 7 Fire Crystal and 6 Ice Crystal.

The chain crosses three disciplines — Carpenter to Lv 74, Blacksmith to Lv 74 and Goldsmith to Lv 71 — 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, Bluespirit Tile has the widest use: 72 recipes call for it, spanning six of the eight crafting classes.
