Stiperstone Grinding Wheel

Taken all the way down to base materials, one Stiperstone Grinding Wheel is 3 crafting steps deep and needs 3 intermediates — Larch Lumber ×2, High Steel Ingot ×1 and High Steel Nugget ×1 — which resolve to 5 distinct raw materials totalling 19 units, plus 18 crystals.

That bill outweighs 7,589 of the 13,602 recipes tracked here and 777 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 12 are burned by the intermediates, so the real crystal cost is 9 Wind Crystal, 6 Fire Crystal and 3 Ice Crystal.

The chain crosses two disciplines — Carpenter to Lv 62 and Blacksmith to Lv 62 — so no single class can finish it unaided.

All 5 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, High Steel Nugget has the widest use: 133 recipes call for it, spanning seven of the eight crafting classes.
