Hingan Fence (Mokuzo)

Taken all the way down to base materials, one Hingan Fence (Mokuzo) is 3 crafting steps deep and needs 3 intermediates — High Steel Ingot ×20, Birch Lumber ×15 and High Steel Nugget ×20 — which resolve to 5 distinct raw materials totalling 275 units, plus 219 crystals.

That bill outweighs 13,586 of the 13,602 recipes tracked here and 1,929 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 24 of those crystals go into the final step; the other 195 are burned by the intermediates, so the real crystal cost is 132 Fire Crystal, 75 Wind Crystal and 12 Earth Crystal.

The chain crosses two disciplines — Blacksmith to Lv 62 and Carpenter to Lv 58 — 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.
