Riviera Cottage Wall (Stone)

Taken all the way down to base materials, one Riviera Cottage Wall (Stone) is 3 crafting steps deep and needs 2 intermediates — Mortar ×15 and Distilled Water ×15 — which resolve to 3 distinct raw materials totalling 120 units, plus 42 crystals.

That bill outweighs 13,498 of the 13,602 recipes tracked here and 2,185 of the 2,216 Goldsmith ones, and 337 recipes nest deeper.

Only 12 of those crystals go into the final step; the other 30 are burned by the intermediates, so the real crystal cost is 30 Water Shard, 8 Wind Shard and 4 Fire Shard.

The chain crosses two disciplines — Goldsmith to Lv 22 and Alchemist to Lv 20 — 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, Mortar has the widest use: 140 recipes call for it, spanning six of the eight crafting classes.
