Hingan House Wall (Mokuzo)

Taken all the way down to base materials, one Hingan House Wall (Mokuzo) is 3 crafting steps deep and needs 5 intermediates — Clear Glass Lens ×10, Cut Stone ×10, Dark Chestnut Lumber ×10 and 2 others — which resolve to 6 distinct raw materials totalling 165 units, plus 206 crystals.

That bill outweighs 13,537 of the 13,602 recipes tracked here and 1,536 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 36 of those crystals go into the final step; the other 170 are burned by the intermediates, so the real crystal cost is 110 Wind Crystal, 50 Water Shard, 30 Wind Shard and 1 other kind.

The chain crosses three disciplines — Carpenter to Lv 66, Goldsmith to Lv 30 and Alchemist to Lv 28 — so no single class can finish it unaided.

All 6 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, Cut Stone has the widest use: 103 recipes call for it, spanning six of the eight crafting classes.
