Carbuncle Desk ★★★

Taken all the way down to base materials, one Carbuncle Desk is 3 crafting steps deep and needs 5 intermediates — Undyed Woolen Cloth ×6, Mahogany Lumber ×4, Spruce Lumber ×4 and 2 others — which resolve to 5 distinct raw materials totalling 38 units, plus 68 crystals.

That bill outweighs 11,698 of the 13,602 recipes tracked here and 1,218 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 3 of those crystals go into the final step; the other 65 are burned by the intermediates, so the real crystal cost is 30 Lightning Shard, 20 Wind Shard, 12 Wind Crystal and 3 other kinds.

The chain crosses three disciplines — Carpenter to Lv 50, Goldsmith to Lv 50 and Weaver to Lv 39 — so no single class can finish it unaided.

3 of the 5 raw materials come out of the ground, and 2 of them are time-gated: Raw Ruby (18:00) and Spruce Log (9:00). The widest gap between consecutive opening times is 15 Eorzean hours, about 44 real-world minutes.

Of the intermediates, Undyed Woolen Cloth has the widest use: 154 recipes call for it, spanning seven of the eight crafting classes.
