Royal Leather Sofa

Taken all the way down to base materials, one Royal Leather Sofa is 2 crafting steps deep and needs 3 intermediates — Gomphotherium Leather ×5, Dark Mahogany Lumber ×2 and Lar Ingot ×2 — which resolve to 6 distinct raw materials totalling 50 units, plus 88 crystals.

That bill outweighs 12,777 of the 13,602 recipes tracked here and 1,823 of the 1,844 Leatherworker ones, and 4,464 recipes nest deeper.

Only 16 of those crystals go into the final step; the other 72 are burned by the intermediates, so the real crystal cost is 48 Earth Crystal and 40 Wind Crystal.

The chain crosses three disciplines — Leatherworker to Lv 96, Carpenter to Lv 94 and Goldsmith to Lv 91 — so no single class can finish it unaided.

4 of the 6 raw materials match a gathering node, none of them timed; the other 2 come from vendors, drops or content this site does not track.

Of the intermediates, Lar Ingot has the widest use: 101 recipes call for it, spanning six of the eight crafting classes.
