Riviera Bookshelf

Taken all the way down to base materials, one Riviera Bookshelf is 3 crafting steps deep and needs 5 intermediates — Mahogany Lumber ×3, Cobalt Plate ×2, Varnish ×2 and 2 others — which resolve to 6 distinct raw materials totalling 40 units, plus 88 crystals.

That bill outweighs 11,825 of the 13,602 recipes tracked here and 1,258 of the 1,441 Armorer ones, and 337 recipes nest deeper.

Only 12 of those crystals go into the final step; the other 76 are burned by the intermediates, so the real crystal cost is 35 Fire Shard, 16 Ice Shard, 16 Water Shard and 2 other kinds.

The chain crosses four disciplines — Armorer to Lv 48, Blacksmith to Lv 42, Alchemist to Lv 41 and Carpenter to Lv 39 — so no single class can finish it unaided.

5 of the 6 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.
