Adamantite Revolver

Taken all the way down to base materials, one Adamantite Revolver is 3 crafting steps deep and needs 7 intermediates — Adamantite Nugget ×2, Birch Lumber ×1, Black Firesand ×1 and 4 others — which resolve to 14 distinct raw materials totalling 48 units, plus 43 crystals.

That bill outweighs 12,691 of the 13,602 recipes tracked here and 1,712 of the 1,932 Blacksmith ones, and 337 recipes nest deeper.

Only 10 of those crystals go into the final step; the other 33 are burned by the intermediates, so the real crystal cost is 30 Fire Crystal, 5 Earth Crystal, 5 Wind Crystal and 1 other kind.

The chain crosses three disciplines — Blacksmith to Lv 58, Carpenter to Lv 58 and Alchemist to Lv 32 — so no single class can finish it unaided.

All 14 raw materials are gathered, and 2 of them are time-gated: Adamantite Ore (0:00, 2:00, 6:00, 10:00, 12:00, 14:00, 18:00, 22:00) and Darksteel Ore (1:00). The widest gap between consecutive opening times is 4 Eorzean hours, about 12 real-world minutes.

Of the intermediates, Titanium Nugget has the widest use: 112 recipes call for it, spanning six of the eight crafting classes.
