Riviera Mansion Roof (Composite) ★

Taken all the way down to base materials, one Riviera Mansion Roof (Composite) is 3 crafting steps deep and needs 7 intermediates — Cobalt Joint Plate ×10, Cobalt Nails ×10, Oak Lumber ×10 and 4 others — which resolve to 7 distinct raw materials totalling 170 units, plus 390 crystals.

That bill outweighs 13,542 of the 13,602 recipes tracked here and 1,538 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 20 of those crystals go into the final step; the other 370 are burned by the intermediates, so the real crystal cost is 150 Fire Shard, 90 Wind Shard, 80 Water Shard and 3 other kinds.

The chain crosses four disciplines — Carpenter to Lv 50, Armorer to Lv 44, Blacksmith to Lv 44 and Alchemist to Lv 41 — so no single class can finish it unaided.

6 of the 7 raw materials match a gathering node, none of them timed; the other 1 comes from vendors, drops or content this site does not track.

Of the intermediates, Cobalt Ingot has the widest use: 145 recipes call for it, spanning seven of the eight crafting classes.
