Claro Walnut Fishing Rod

Taken all the way down to base materials, one Claro Walnut Fishing Rod is 2 crafting steps deep and needs 3 intermediates — Claro Walnut Lumber ×2, Ra'Kaznar Ingot ×2 and Acacia Lumber ×1 — which resolve to 4 distinct raw materials totalling 27 units, plus 56 crystals.

That bill outweighs 9,763 of the 13,602 recipes tracked here and 1,005 of the 1,552 Carpenter ones, and 4,464 recipes nest deeper.

Only 16 of those crystals go into the final step; the other 40 are burned by the intermediates, so the real crystal cost is 32 Wind Crystal, 16 Fire Crystal and 8 Ice Crystal.

The chain crosses two disciplines — Carpenter to Lv 100 and Blacksmith to Lv 98 — 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, Ra'Kaznar Ingot has the widest use: 166 recipes call for it, spanning seven of the eight crafting classes.
