Riviera House Wall (Wood)

Taken all the way down to base materials, one Riviera House Wall (Wood) is 3 crafting steps deep and needs 4 intermediates — Oak Lumber ×10, Steel Joint Plate ×10, Steel Nails ×10 and 1 other — which resolve to 4 distinct raw materials totalling 105 units, plus 162 crystals.

That bill outweighs 13,478 of the 13,602 recipes tracked here and 1,513 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 32 of those crystals go into the final step; the other 130 are burned by the intermediates, so the real crystal cost is 70 Fire Shard, 46 Ice Shard and 46 Wind Shard.

The chain crosses three disciplines — Carpenter to Lv 38, Armorer to Lv 27 and Blacksmith to Lv 27 — 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, Steel Ingot has the widest use: 125 recipes call for it, spanning seven of the eight crafting classes.
