Riviera House Wall (Stone)

Taken all the way down to base materials, one Riviera House Wall (Stone) is 3 crafting steps deep and needs 3 intermediates — Mortar ×30, Cut Stone ×10 and Distilled Water ×30 — which resolve to 4 distinct raw materials totalling 165 units, plus 126 crystals.

That bill outweighs 13,537 of the 13,602 recipes tracked here and 2,193 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 36 of those crystals go into the final step; the other 90 are burned by the intermediates, so the real crystal cost is 60 Water Shard, 50 Wind Shard and 16 Fire Shard.

The chain crosses two disciplines — Goldsmith to Lv 39 and Alchemist to Lv 20 — 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, Mortar has the widest use: 140 recipes call for it, spanning six of the eight crafting classes.
