Pactmaker's Lapidary Hammer ★★

Taken all the way down to base materials, one Pactmaker's Lapidary Hammer is 2 crafting steps deep and needs 3 intermediates — Eblan Danburite ×3, Lunar Adamantite Ingot ×3 and Chondrite Ingot ×1 — which resolve to 8 distinct raw materials totalling 45 units, plus 50 crystals.

That bill outweighs 12,451 of the 13,602 recipes tracked here and 1,645 of the 1,932 Blacksmith ones, and 4,464 recipes nest deeper.

Only 6 of those crystals go into the final step; the other 44 are burned by the intermediates, so the real crystal cost is 21 Fire Cluster, 12 Earth Cluster, 9 Wind Cluster and 1 other kind.

The chain crosses two disciplines — Blacksmith to Lv 90 and Goldsmith to Lv 90 — so no single class can finish it unaided.

4 of the 8 raw materials come out of the ground, and 2 of them are time-gated: Lunar Adamantite Ore (2:00, 14:00) and Raw Eblan Danburite (0:00, 12:00). The widest gap between consecutive opening times is 10 Eorzean hours, about 29 real-world minutes.

Of the intermediates, Chondrite Ingot has the widest use: 210 recipes call for it, spanning seven of the eight crafting classes.
