Deepgold Saw

Taken all the way down to base materials, one Deepgold Saw is 2 crafting steps deep and needs 2 intermediates — Deepgold Nugget ×3 and White Oak Lumber ×1 — which resolve to 3 distinct raw materials totalling 19 units, plus 35 crystals.

That bill outweighs 7,589 of the 13,602 recipes tracked here and 804 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 11 of those crystals go into the final step; the other 24 are burned by the intermediates, so the real crystal cost is 24 Fire Crystal, 6 Wind Crystal and 5 Earth Crystal.

The chain crosses two disciplines — Blacksmith to Lv 71 and Carpenter to Lv 71 — so no single class can finish it unaided.

All 3 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, Deepgold Nugget has the widest use: 55 recipes call for it, spanning six of the eight crafting classes.
