Adamant Cane ★★

Taken all the way down to base materials, one Adamant Cane is 2 crafting steps deep and needs 3 intermediates — Prismatic Ingot ×3, Alumina Whetstone ×2 and Lignum Vitae Lumber ×1 — which resolve to 8 distinct raw materials totalling 41 units, plus 31 crystals.

That bill outweighs 11,923 of the 13,602 recipes tracked here and 1,918 of the 2,216 Goldsmith ones, and 4,464 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 27 are burned by the intermediates, so the real crystal cost is 12 Fire Cluster, 12 Wind Cluster and 7 Wind Crystal.

The chain crosses two disciplines — Goldsmith to Lv 80 and Carpenter to Lv 78 — so no single class can finish it unaided.

3 of the 8 raw materials come out of the ground, and 2 of them are time-gated: Beryllium Ore (4:00, 16:00) and Prismstone (4:00, 16:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Lignum Vitae Lumber has the widest use: 134 recipes call for it, spanning seven of the eight crafting classes.
