Black Willow Fishing Rod ★★★

Taken all the way down to base materials, one Black Willow Fishing Rod is 4 crafting steps deep and needs 6 intermediates — Black Willow Lumber ×6, Hawk's Eye Sand ×3, Nightsteel Ingot ×2 and 3 others — which resolve to 14 distinct raw materials totalling 56 units, plus 41 crystals.

That bill outweighs 12,997 of the 13,602 recipes tracked here and 1,392 of the 1,552 Carpenter ones, and 1 recipe nests deeper.

Only 4 of those crystals go into the final step; the other 37 are burned by the intermediates, so the real crystal cost is 10 Wind Cluster, 8 Ice Cluster, 6 Fire Crystal and 4 other kinds.

The chain crosses four disciplines — Carpenter to Lv 70, Alchemist to Lv 70, Blacksmith to Lv 70 and Goldsmith to Lv 50 — so no single class can finish it unaided.

8 of the 14 raw materials come out of the ground, and 5 of them are time-gated: Black Willow Log (4:00, 16:00), Hawk's Eye (6:00, 18:00) and 3 others. The widest gap between consecutive opening times is 10 Eorzean hours, about 29 real-world minutes.

Of the intermediates, Gold Ingot has the widest use: 184 recipes call for it, spanning seven of the eight crafting classes.
