Dark Mahogany Cane

Taken all the way down to base materials, one Dark Mahogany Cane is 3 crafting steps deep and needs 5 intermediates — Cobalt Tungsten Ingot ×2, Dark Mahogany Lumber ×2, Ihuykanite ×1 and 2 others — which resolve to 6 distinct raw materials totalling 36 units, plus 79 crystals.

That bill outweighs 11,383 of the 13,602 recipes tracked here and 1,184 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 15 of those crystals go into the final step; the other 64 are burned by the intermediates, so the real crystal cost is 56 Wind Crystal, 16 Fire Crystal and 7 Ice Crystal.

The chain crosses three disciplines — Carpenter to Lv 94, Blacksmith to Lv 94 and Goldsmith to Lv 92 — so no single class can finish it unaided.

All 6 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, Star Quartz has the widest use: 157 recipes call for it, spanning seven of the eight crafting classes.
