Hardsilver Lapidary Hammer

Taken all the way down to base materials, one Hardsilver Lapidary Hammer is 3 crafting steps deep and needs 8 intermediates — Hardsilver Ingot ×2, Agate ×1, Electrum Ingot ×1 and 5 others — which resolve to 9 distinct raw materials totalling 37 units, plus 54 crystals.

That bill outweighs 11,564 of the 13,602 recipes tracked here and 1,403 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 9 of those crystals go into the final step; the other 45 are burned by the intermediates, so the real crystal cost is 30 Wind Crystal, 10 Wind Shard, 5 Fire Crystal and 2 other kinds.

The chain crosses four disciplines — Blacksmith to Lv 57, Alchemist to Lv 56, Carpenter to Lv 56 and Goldsmith to Lv 56 — so no single class can finish it unaided.

All 9 raw materials are gathered, and one of them is time-gated: Abalathian Mistletoe (6:00, 18:00). The widest gap between consecutive opening times is 12 Eorzean hours, about 35 real-world minutes.

Of the intermediates, Electrum Ingot has the widest use: 234 recipes call for it, spanning seven of the eight crafting classes.
