Riviera House Roof (Stone)

Taken all the way down to base materials, one Riviera House Roof (Stone) is 3 crafting steps deep and needs 5 intermediates — Walnut Lumber ×15, Roof Tile ×10, Steel Joint Plate ×10 and 2 others — which resolve to 5 distinct raw materials totalling 135 units, plus 176 crystals.

That bill outweighs 13,522 of the 13,602 recipes tracked here and 1,531 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 36 of those crystals go into the final step; the other 140 are burned by the intermediates, so the real crystal cost is 70 Fire Shard, 50 Wind Shard, 46 Ice Shard and 1 other kind.

The chain crosses four disciplines — Carpenter to Lv 41, Armorer to Lv 27, Blacksmith to Lv 27 and Alchemist to Lv 11 — so no single class can finish it unaided.

All 5 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, Walnut Lumber has the widest use: 128 recipes call for it, spanning eight of the eight crafting classes.
