Deepgold Lapidary Hammer

Taken all the way down to base materials, one Deepgold Lapidary Hammer is 2 crafting steps deep and needs 3 intermediates — Stonegold Nugget ×2, Deepgold Nugget ×1 and White Oak Lumber ×1 — which resolve to 4 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 18 Wind Crystal, 12 Fire Crystal and 5 Earth Crystal.

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

All 4 raw materials are gathered, and one of them is time-gated: Gold Ore (9:00). That window comes round once per Eorzean day, every 70 real-world minutes.

Of the intermediates, Stonegold Nugget has the widest use: 90 recipes call for it, spanning six of the eight crafting classes.
