Rarefied Lignum Vitae Grinding Wheel

Taken all the way down to base materials, one Rarefied Lignum Vitae Grinding Wheel is 2 crafting steps deep and needs 3 intermediates — Lignum Vitae Lumber ×2, Dwarven Mythril Ingot ×1 and Tuff Whetstone ×1 — which resolve to 4 distinct raw materials totalling 16 units, plus 42 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 14 of those crystals go into the final step; the other 28 are burned by the intermediates, so the real crystal cost is 28 Wind Crystal, 7 Fire Crystal and 7 Ice Crystal.

The chain crosses three disciplines — Carpenter to Lv 80, Blacksmith to Lv 78 and Goldsmith to Lv 76 — 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, Dwarven Mythril Ingot has the widest use: 168 recipes call for it, spanning seven of the eight crafting classes.
