Black Willow Cane ★★★

Taken all the way down to base materials, one Black Willow Cane is 3 crafting steps deep and needs 7 intermediates — Black Willow Lumber ×3, Grade 3 Reisui of Mind ×3, Imperial Jade ×2 and 4 others — which resolve to 16 distinct raw materials totalling 48 units, plus 42 crystals.

That bill outweighs 12,691 of the 13,602 recipes tracked here and 1,342 of the 1,552 Carpenter ones, and 337 recipes nest deeper.

Only 4 of those crystals go into the final step; the other 38 are burned by the intermediates, so the real crystal cost is 22 Wind Crystal, 8 Wind Cluster, 6 Ice Cluster and 3 other kinds.

The chain crosses three disciplines — Carpenter to Lv 70, Alchemist to Lv 70 and Goldsmith to Lv 70 — so no single class can finish it unaided.

11 of the 16 raw materials come out of the ground, and 4 of them are time-gated: Black Willow Log (4:00, 16:00), Gyr Abanian Spring Water (10:00, 22:00) and 2 others. The widest gap between consecutive opening times is 6 Eorzean hours, about 18 real-world minutes.

Of the intermediates, Durium Nugget has the widest use: 142 recipes call for it, spanning seven of the eight crafting classes.
