Acacia Fishing Rod

Taken all the way down to base materials, one Acacia Fishing Rod is 2 crafting steps deep and needs 3 intermediates — Acacia Lumber ×2, Cobalt Tungsten Ingot ×1 and Dark Mahogany Lumber ×1 — which resolve to 4 distinct raw materials totalling 21 units, plus 48 crystals.

That bill outweighs 8,152 of the 13,602 recipes tracked here and 815 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 16 of those crystals go into the final step; the other 32 are burned by the intermediates, so the real crystal cost is 32 Wind Crystal, 8 Fire Crystal and 8 Ice Crystal.

The chain crosses two disciplines — Carpenter to Lv 97 and Blacksmith to Lv 94 — so no single class can finish it unaided.

All 4 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, Cobalt Tungsten Ingot has the widest use: 105 recipes call for it, spanning six of the eight crafting classes.
