Black Willow Spear ★★★

Taken all the way down to base materials, one Black Willow Spear is 4 crafting steps deep and needs 6 intermediates — Black Willow Lumber ×3, Grade 3 Reisui of Strength ×3, Azurite ×2 and 3 others — which resolve to 14 distinct raw materials totalling 43 units, plus 36 crystals.

That bill outweighs 12,178 of the 13,602 recipes tracked here and 1,293 of the 1,552 Carpenter ones, and 1 recipe nests deeper.

Only 4 of those crystals go into the final step; the other 32 are burned by the intermediates, so the real crystal cost is 10 Wind Crystal, 6 Fire Crystal, 6 Ice Cluster and 5 other kinds.

The chain crosses four disciplines — Carpenter to Lv 70, Alchemist to Lv 70, Blacksmith to Lv 70 and Goldsmith to Lv 66 — so no single class can finish it unaided.

9 of the 14 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, High Steel Nugget has the widest use: 133 recipes call for it, spanning seven of the eight crafting classes.
