Rarefied Zelkova Spinning Wheel

Taken all the way down to base materials, one Rarefied Zelkova Spinning Wheel is 3 crafting steps deep and needs 3 intermediates — Zelkova Lumber ×3, Tama-hagane Ingot ×1 and Oroshigane Ingot ×1 — which resolve to 4 distinct raw materials totalling 21 units, plus 35 crystals.

That bill outweighs 8,152 of the 13,602 recipes tracked here and 815 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 11 of those crystals go into the final step; the other 24 are burned by the intermediates, so the real crystal cost is 21 Wind Crystal, 9 Fire Crystal and 5 Ice Crystal.

The chain crosses two disciplines — Carpenter to Lv 70 and Blacksmith to Lv 66 — 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, Oroshigane Ingot has the widest use: 114 recipes call for it, spanning six of the eight crafting classes.
