Hingan House Wall (Kura-zukuri)

Taken all the way down to base materials, one Hingan House Wall (Kura-zukuri) is 3 crafting steps deep and needs 6 intermediates — Clear Glass Lens ×10, Felt Lining ×10, Persimmon Lumber ×10 and 3 others — which resolve to 10 distinct raw materials totalling 245 units, plus 296 crystals.

That bill outweighs 13,581 of the 13,602 recipes tracked here and 1,435 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 36 of those crystals go into the final step; the other 260 are burned by the intermediates, so the real crystal cost is 90 Fire Crystal, 70 Water Shard, 50 Lightning Shard and 3 other kinds.

The chain crosses five disciplines — Armorer to Lv 66, Carpenter to Lv 66, Blacksmith to Lv 56, Weaver to Lv 42 and Alchemist to Lv 28 — so no single class can finish it unaided.

9 of the 10 raw materials match a gathering node, none of them timed; the other 1 comes from vendors, drops or content this site does not track.

Of the intermediates, Titanium Nugget has the widest use: 112 recipes call for it, spanning six of the eight crafting classes.
