Red Pine Grinding Wheel

Taken all the way down to base materials, one Red Pine Grinding Wheel is 2 crafting steps deep and needs 3 intermediates — Red Pine Lumber ×2, Chloroschist Whetstone ×1 and Phrygian Gold Ingot ×1 — which resolve to 4 distinct raw materials totalling 20 units, plus 47 crystals.

That bill outweighs 7,876 of the 13,602 recipes tracked here and 791 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 15 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 7 Ice Crystal.

The chain crosses two disciplines — Carpenter to Lv 85 and Goldsmith to Lv 84 — 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, Phrygian Gold Ingot has the widest use: 82 recipes call for it, spanning seven of the eight crafting classes.
