Riviera Cottage Wall (Composite)

Taken all the way down to base materials, one Riviera Cottage Wall (Composite) is 3 crafting steps deep and needs 4 intermediates — Iron Joint Plate ×10, Iron Nails ×10, Elm Lumber ×5 and 1 other — which resolve to 3 distinct raw materials totalling 105 units, plus 53 crystals.

That bill outweighs 13,478 of the 13,602 recipes tracked here and 2,179 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 8 of those crystals go into the final step; the other 45 are burned by the intermediates, so the real crystal cost is 34 Fire Shard, 10 Ice Shard and 9 Wind Shard.

The chain crosses four disciplines — Goldsmith to Lv 20, Blacksmith to Lv 16, Carpenter to Lv 16 and Armorer to Lv 15 — so no single class can finish it unaided.

All 3 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, Iron Ingot has the widest use: 113 recipes call for it, spanning seven of the eight crafting classes.
